Question: 1
Refer to the exhibit.

Which two initial cluster configuration tasks were missed during the deployment process?
(Choose two.)

A. Host password changes

B. Password policy changes
C. BIOS password changes
D. CVM password changes

Answer: A, D
Explanation:
According to the image description, the exhibit shows a screenshot of a computer screen with a
table of data. The table has 6 columns and 4 rows. The columns are labeled “Date”, “Time”,
“Status”, “Details”, “Configuration”, and “Duration”. The rows contain information about
different configurations and their statuses. The background is a light blue color. There is a pop-
up message on the bottom right corner of the screen that reads “This question has been
answered. Click here to enable the edit button.”
Based on the table data, it seems that the screenshot is taken from the Prism Central web
console, showing the results of a cluster health check report. The report shows that there are
four failed checks: Host Password Policy, CVM Password Policy, NTP Configuration, and Cluster
Time Skew2. These checks indicate that some initial cluster configuration tasks were missed
during the deployment process.
The Host Password Policy check verifies that the host passwords are not set to default values
and are compliant with the password policy defined in Prism Central3. The CVM Password Policy
check verifies that the CVM passwords are not set to default values and are compliant with the
password policy defined in Prism Central4. These checks are important for ensuring the security

and compliance of the cluster. Therefore, changing the host and CVM passwords from their
default values and following the password policy guidelines are two initial cluster configuration
tasks that were missed.

Question: 2
An administrator needs to configure a new subnet on an AHV cluster and want to ensure that
VMs will automatically be assigned an IP address at creation time.
Which type of network does the administrator need to create?

A. Dynamic Network
B. Unmanaged Network
C. Managed Network
D. DHCP Network

Answer: C
Explanation:
A managed network is a type of network that can be created on an AHV cluster and allows VMs
to automatically be assigned an IP address at creation time. A managed network uses the
Nutanix IP Address Management (IPAM) service, which provides DHCP and DNS functionality for
the VMs on the network. A managed network can be configured with a subnet range, a default
gateway, and DNS servers. The IPAM service will allocate IP addresses from the subnet range to
the VMs and register their hostnames in the DNS servers. The IPAM service will also release the
IP addresses when the VMs are deleted or moved to another network1.
To create a managed network on an AHV cluster, the administrator can use Prism Element or
Prism Central. The steps are as follows2:
In Prism Element, go to the Network Configuration page and click Create Network.
In Prism Central, go to the Networks page and click Create.
Enter a name and description for the network.
Select Managed as the network type.
Enter the subnet range, default gateway, and DNS servers for the network.
Optionally, enable VLAN tagging and enter a VLAN ID for the network.
Click Save.

Question: 3
An administrator was reviewing various AOS logs when a it was noticed that the time of the logs
were off by several hours.
Which initial step was missed during the post process cluster configuration?

A. Setting the cluster time zone via PC GUI

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
B. Setting the cluster time zone via CVM NCLI
C. Setting the cluster time zone via PE GUI
D. Setting the cluster time zone via CVM ACLI

Answer: B
Explanation:
The cluster time zone is a setting that determines the time zone used by all CVMs in the cluster.
The cluster time zone affects the timestamps of Nutanix logs, events, alerts, and reports. The
cluster time zone also affects the scheduling of tasks such as snapshots, replication, and
upgrades. By default, the cluster time zone is set to UTC (Coordinated Universal Time) when the
cluster is created3.
To change the cluster time zone, the administrator needs to use the ncli (Nutanix command-line
interface) on any CVM in the cluster. The steps are as follows4:
Log in to any CVM using SSH.
Run ncli cluster get-timezone to check the current cluster time zone.
Run ncli cluster set-timezone timezone=<timezone> to change the cluster time zone,
where <timezone> is a valid time zone identifier (for example, America/New_York).
Run ncli cluster get-timezone again to verify that the cluster time zone has been changed.
Note that changing the cluster time zone does not affect the time zone of Prism Element or
Prism Central VMs. To change their time zone, the administrator needs to use Prism Element UI
or Prism Central UI respectively5.

Question: 4
Which AOS process determine if an I/O from a user will be written to OpLog or to an Extent
Store?

A. Stargate
B. Curtor
C. Cassandara
D. Zeus

Answer: A
Explanation:
Stargate is the AOS process that handles all I/O operations for the cluster. It is responsible for
determining whether an I/O from a user will be written to the OpLog or to the Extent Store,
based on the type and size of the I/O. Stargate also performs data tiering, compression,
deduplication, and erasure coding1. Stargate runs on every CVM and communicates with other
Stargates to ensure data locality and redundancy2.

 Question: 5
A recently configured cluster is leveraging NearSync with a recovery schedule of 15 minutes. It is
noticed that the cluster is consistently transitioning in an Out of NearSyne.
What action should be taken to potentially address this issue?

A. Increase network bandwidth

B. Change the NearSync schedule to 30 minutes.
C. Add a vCPUs to the user VMs.
D. Configure a secondary schedule in the same Protection Domain.

Answer: A
Explanation:
One of the possible reasons for a cluster to transition out of NearSync is insufficient network
bandwidth between the source and target clusters. NearSync requires a minimum network
bandwidth of 10 Mbps per VM for replication3. If the network bandwidth is lower than the
required amount, the replication of recovery points may take longer than the configured RPO,
resulting in an Out of NearSync condition. To address this issue, you can increase the network
bandwidth between the clusters or reduce the number of VMs protected by NearSync4.

Question: 6
Which scenario would benefit most from Erasure Coding being enabled on a container?

A. Long term storage of data which is written once and read infrequently
B. High performance database where all is relatively hot.
C. VDI use cases where a single VM is cloned 100’s of times
D. WEB and API Servers

Answer: A
Explanation:
The correct answer is A. Long term storage of data which is written once and read infrequently.
Erasure Coding is a feature that increases the usable capacity on a Nutanix cluster by reducing
the amount of data replication. Instead of replicating data, Erasure Coding uses parity
information to rebuild data in the event of a disk failure. The capacity savings of Erasure Coding
is in addition to deduplication and compression savings1.
Erasure Coding is most beneficial for scenarios where the data is written once and read
infrequently, such as long term storage of archival data, backup data, or cold data. This is
because Erasure Coding has some trade-offs and limitations that may affect the performance
and availability of the cluster. Some of these trade-offs and limitations are2:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Erasure Coding requires more CPU and memory resources than replication, as it involves more
complex calculations for encoding and decoding data.
Erasure Coding increases the network bandwidth consumption, as it involves more data
transfers between nodes for encoding and decoding data.
Erasure Coding reduces the resiliency of the cluster, as it can tolerate fewer node failures than
replication. For example, a cluster with redundancy factor 2 can tolerate one node failure with
replication, but only two disk failures with Erasure Coding.
Erasure Coding is not effective for workloads that have many overwrites or random writes, as it
involves more overhead for updating the parity information.
Erasure Coding is not supported for some features, such as volume groups, file server VMs, or
Metro Availability.
Therefore, if an administrator needs to configure a container on a Nutanix cluster, they should
enable Erasure Coding only if the container will store data that is written once and read
infrequently. This way, they can maximize the capacity savings of Erasure Coding without
compromising the performance and availability of the cluster.

Question: 7
An administrator logs into the Nutanix Support Portal and notices there is a new version of the
LCM Framework available. In an effort ensure LCM is providing the latest features, the
administrator would like to upgrade LCM.
How can the LCM Framework be upgraded?

A. Perform an LCM inventory

B. Upload the latest LCM Framework as an image in the image Configuration in Prism
C. Upload the latest LCM Framework bundle via Upgrade Software in Prism
D. Upgrade AOS

Answer: A
Explanation:
LCM (Life Cycle Manager) is a feature that allows Nutanix administrators to perform one-click
firmware and software upgrades for Nutanix clusters and components. LCM fetches inventory
and update information from a pre-configured URL that contains the latest versions of firmware
and software packages. However, upgrading Nutanix AOS does not automatically update the
fetch URL. To update the fetch URL, the administrator needs to update the LCM framework. The
LCM framework is the core component of LCM that provides the logic and functionality for
inventory, download, and upgrade operations1.
To upgrade the LCM framework, the administrator needs to perform an LCM inventory. An LCM
inventory is a process that scans the cluster and its components for their current firmware and
software versions and compares them with the available versions from the fetch URL. If there is
a newer version of the LCM framework available, it will be shown as an update option under
Cluster Software Component in the Available Updates page. The administrator can then select
and apply the LCM framework update to upgrade it to the latest version2.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
The administrator can perform an LCM inventory using Prism Element or Prism Central. The
steps are as follows3:
In Prism Element, go to the Network Configuration page and click Life Cycle Management.
In Prism Central, go to the Services page and click Life Cycle Management.
Click Inventory in the toolbar and select Perform Inventory from the drop-down menu.
Wait for the inventory process to complete and check for any available updates.

Question: 8
An administrator has been asked to enable block awareness and increase the fault tolerance to
FT2 on a Nutanix AHV cluster with the following configuration:
Four blocks
One node per block
Will the administrator be able to accomplish these tasks?

A. No-Fault tolerance changes are not supported.

B. Yes-FT2 requires a minimum of three nodes.
C. Yes-Block awareness requires a minimum of three blocks.
D. No-FT2 requires a minimum of five nodes.

Answer: D
Explanation:
Fault tolerance (FT) is the ability of a cluster to withstand node failures and maintain data
availability. FT is determined by the replication factor (RF) of the data, which is the number of
copies of each data block stored on different nodes. FT = RF - 1, meaning that the cluster can
tolerate as many node failures as one less than the RF. Block awareness is a feature that
enhances fault tolerance by ensuring that data copies are distributed across different blocks,
which are groups of nodes that share a power source and network switch. Block awareness
requires a minimum of three blocks and a minimum of six nodes in the cluster.
In this scenario, the administrator has been asked to enable block awareness and increase the
fault tolerance to FT2 on a Nutanix AHV cluster with the following configuration: Four blocks,
One node per block. The administrator will not be able to accomplish these tasks because:
To enable block awareness, the cluster needs at least six nodes, but it only has four nodes.
To increase the fault tolerance to FT2, the cluster needs at least five nodes per RF3 or seven
nodes per RF4, but it only has four nodes.
Therefore, the administrator will need to add more nodes to the cluster before enabling block
awareness and increasing the fault tolerance to FT2.

Question: 9
What Nutanix feature provides effective caching optimization In VDI environments?

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A. Remote Protection Group
B. Local Protection Group
C. Snap Clones
D. Shadow Clones

Answer: D
Explanation:
Shadow Clones is a Nutanix feature that provides effective caching optimization in VDI
environments. VDI stands for Virtual Desktop Infrastructure, which is a technology that allows
users to access virtual desktops hosted on a centralized server. VDI environments typically have
a high degree of similarity among desktop images, which means that many VMs access the same
data blocks from the storage layer. Shadow Clones leverages this similarity by creating read-only
copies of frequently accessed data blocks on each node’s SSD tier, reducing network traffic and
improving performance. Shadow Clones works automatically and transparently without any
configuration or intervention from the administrator.

Question: 10
Which capability refers to the storage of VM data on the node where the VM is running and
ensure that the read I/O does not have to traverse the network?

A. Intelligent Locally
B. Data Locality
C. Intelligent Tiering
D. Data Tiering

Answer: B
Explanation:
Data locality is the capability of storing VM data on the node where the VM is running and
ensuring that the read I/O does not have to traverse the network. Data locality is a unique
feature of Nutanix that provides high performance and low latency for VMs by minimizing
network traffic and crosstalk. Data locality works by writing one copy of the data local to the VM
and the other copy (or copies) on other nodes. When a VM migrates to another node, Nutanix
also moves its data to the new node and serves all I/O requests locally. Data locality also adapts
to changing workloads and access patterns by dynamically moving data to where it is needed
most1.

An administrator has received reports of users being disconnected from remote desktop
sessions to a specific VM.
Which VM metric is most useful isolating the cause of the issue?

A. Storage Controller Bandwidth

B. Swap-Out Rate
C. Hypervisor CPU Ready time (%)
D. Virtual NIC receive packet dropped

Answer: D
Explanation:
Virtual NIC receive packet dropped is the most useful VM metric for isolating the cause of users
being disconnected from remote desktop sessions to a specific VM. This metric shows the
number of packets that are dropped by the virtual NIC of the VM due to insufficient buffer space
or other reasons. Packet drops can indicate network congestion, misconfiguration, or
performance issues that can affect the quality and availability of remote desktop
sessions. Packet drops can also cause retransmissions, delays, and errors in TCP-based protocols
such as RDP2. To view this metric in Prism, go to Entities > Compute & Storage > VMs >
Summary View and select a VM. Then, in the Details View, go to Metrics > Performance and
select Virtual NIC receive packet dropped from the drop-down menu3.

Question: 12
What does Nutanix recommend when setting up the node networkring?

A. Include NIC models from different vendors in the same bond

B. Include at least two physically interfaces in every bond.
C. Combine NIC models from different vendors in the same bond.
D. Combine NIC models from different vendors in the same bond.

Answer: B
Explanation:
A bond is a logical interface that combines two or more physical interfaces on an AHV host. A
bond provides high availability and load balancing for the network traffic of the host and its
VMs. A bond can have different modes that determine how the traffic is distributed and how
the bond handles failures of the physical interfaces. The most common bond modes are active-
backup, active-active, and LACP1.
Nutanix recommends including at least two physical interfaces in every bond to ensure high
availability and redundancy. If one of the physical interfaces fails or is disconnected, the other
interface can take over the traffic without affecting the connectivity of the host or its
VMs. Having at least two physical interfaces in a bond also allows for maintenance operations
such as firmware upgrades or cable replacements without downtime2.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Nutanix does not recommend including NIC models from different vendors in the same bond, as
this may cause compatibility issues or performance degradation. Nutanix also does not
recommend using only one physical interface in a bond, as this provides no redundancy or load
balancing benefits3.

Question: 13
An administrator is not able to log into Prism Central by using a new Active Directory user
account. After Logging with the local user, the administrator verified that Directory Services and
Role Mapping setting are valid.
What is the most likely cause of this issue?

A. Change password at next logon attribute is set.

B. User does not belong to the Administrators group.
C. Active Directory functional level of wrong.
D. Prism Element authentication is not configured.

Answer: A
Explanation:
The change password at next logon attribute is a setting that forces a user to change their
password when they log on to a domain for the first time or after their password has
expired. This attribute is enabled by default for new Active Directory user accounts or when an
administrator resets a user’s password4.
However, Prism Central does not support this attribute for Active Directory authentication.
Users with this attribute enabled will not be able to log on to Prism Central using their Active
Directory credentials. They will receive an error message saying “Invalid credentials” or
“Authentication failed” when they try to log on5.
Therefore, if an administrator is not able to log on to Prism Central using a new Active Directory
user account, the most likely cause of this issue is that the change password at next logon
attribute is set for that user account. To resolve this issue, the administrator should disable this
attribute for the user account or log on to a domain workstation first and change their password
before accessing Prism Central6.

Question: 14
Administrator is creating a Windows 10 VM that will be used for a virtual desktop template.
After creating the VM and booting to the ISO, the administrator is unable to install Windows and
receives the following error.

What steps does the administrator need to take to install the OS?

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A. Load the Nutanix VirtIO Serial Bus Driver.
B. Load the VirtIO Network Ethernet Adaper.
C. Load the Nutanix Virtual Balloon Driver.
D. Load the Virtual SCSI pass-through controller.

Answer: D
Explanation:
The error message shown in the image indicates that Windows 10 setup cannot find any drives
to install the OS. This is because the Nutanix AHV hypervisor uses a virtual SCSI pass-through
controller to present disks to the VMs, and Windows 10 does not have a built-in driver for this
device. Therefore, the administrator needs to load the Nutanix VirtIO driver for the virtual SCSI
pass-through controller during the OS installation process. The Nutanix VirtIO driver package
contains various drivers that are specifically used by Windows VMs hosted in the Nutanix
environment to enhance their stability and performance1. The administrator can download the
latest Nutanix VirtIO driver package from the VirtIO downloads page of the Nutanix support
portal. The administrator can then follow these steps to load the driver and install the OS2:
On the Windows 10 setup screen, click Load driver.
Insert a USB drive or mount an ISO image that contains the Nutanix VirtIO driver package.
Browse to the location of the driver package and select the folder that matches the OS
architecture (32-bit or 64-bit).
Select the vioscsi.inf file and click Next.
Wait for the driver to load and then click Refresh.
Select the disk where you want to install Windows 10 and click Next.

Question: 15
Refer to Exhibit:

administrator notices that even though the level parameter is set to EMERGENCY, that all
monitor logs are being sent.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
What is the likely cause of this issue?

A. A second rsyslog server is configured to send all monitor logs.

B. Having the Module Name set to STARGATE sends all monitor logs regardless of the level.
C. A Log Level of EMERGENCY includes all monitor logs.
D. The true setting for Include Monitor Logs sends all monitor logs regardless of the level.

Answer: C
Explanation:

Question: 16
While installing Windows 2019 on a new VM on an AHV cluster, an administrator notices there
aren’t any drives listed for the install.
What might the problem be?

A. VirtIO drivers have not yet been installed and the disks are IDE disks.
B. VirtIO drivers have not yet been installed and the disks are SCSI disks.
C. VirtIO drivers must be installed on AHV for installations of Windows.
D. VirtIO drivers aren’t supported on this version of Windows 2019.

Answer: B
Explanation:
VirtIO drivers are device drivers that are specifically designed for virtualized environments. They
allow the guest operating system to communicate directly with the underlying hardware,
bypassing the emulation layer. This improves the performance and efficiency of the virtual
machines. VirtIO drivers are supported by various hypervisors, including Nutanix AHV1.
Nutanix AHV uses SCSI disks for VMs by default. However, Windows does not have native
support for SCSI disks and requires VirtIO drivers to recognize them. Therefore, if an
administrator is installing Windows 2019 on a new VM on an AHV cluster, they need to install
the VirtIO drivers before selecting the destination disk for the installation. Otherwise, they will
not see any drives listed for the install2.
To install the VirtIO drivers during Windows installation, the administrator can use one of the
following methods3:
Use a VirtIO ISO image that contains the driver files. The administrator can download the VirtIO
ISO image from the Nutanix support portal and upload it to the AHV image service. Then, they
can attach the VirtIO ISO image to the VM as a CD-ROM device and load the driver from it during
Windows installation.
Use a Nutanix Guest Tools (NGT) ISO image that contains the driver files and other tools. The
administrator can download the NGT ISO image from Prism Element or Prism Central and attach
it to the VM as a CD-ROM device. Then, they can load the driver from it during Windows
installation.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Use a floppy disk image that contains only the driver files. The administrator can create a floppy
disk image using tools such as WinImage or WinRAR and upload it to the AHV image service.
Then, they can attach the floppy disk image to the VM as a floppy device and load the driver
from it during Windows installation.

Question: 17
Which baseline is used to identify a Zombie VM?

A. VM is powered off for the past 21 days.

C. VM has no logins for the past 21 days
D. Fewer than 30 1/Os and less than 1000 bytes per day of network traffic for the past 21 days

Answer: D
Explanation:
The correct answer is D. Fewer than 30 I/Os and less than 1000 bytes per day of network traffic
for the past 21 days.
A zombie VM is a type of inactive VM that is powered on but does very little activity. A zombie
VM wastes host resources such as CPU, memory, disk, and network that could be used by other
VMs. A zombie VM can be identified by using the VM Profile feature in Prism Central. The VM
Profile feature analyzes the resource utilization of each VM and assigns it a profile based on its
efficiency and impact on other VMs. The profiles are as follows1:
Efficient: The VM is well-provisioned and has optimal resource utilization.
Over-provisioned: The VM has more resources than it needs and has low resource utilization.
Constrained: The VM has less resources than it needs and has high resource utilization.
Inactive: The VM has no resource utilization and is idle or powered off.
Bully: The VM has high resource utilization and causes contention for other VMs.
A zombie VM is a subtype of an inactive VM that meets the following criteria2:
The VM is powered on for the past 21 days.
The VM does fewer than 30 read or write I/Os (total) per day for the past 21 days.
The VM receives or transfers fewer than 1000 bytes per day of network traffic for the past 21
days.
To identify a zombie VM, the administrator can use Prism Central to view the VM Profile
dashboard and filter by profile type. The dashboard shows the number of VMs in each profile
type, as well as their resource consumption and efficiency score. The administrator can also drill
down into each VM to see its detailed metrics and recommendations for optimization.

Question: 18
An administrator manages a cluster and notices several failed components shown in the exhibit.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
What two options does the administrator have to run all NCC checks manually? (Choose two.)

A. Using the Actions drop-down menu in the Health dashboard of Prism Element.
B. Running ncc health_checks run-alll on the CVM
C. Using the action action drop-down menu in the Health dashboard of Prism Central
D. Running noc health_checks run_all on the PC VM

Answer: A, B
Explanation:
Prism Element and NCC are two ways to run all NCC checks manually on a Nutanix cluster. Prism
Element is the web console that provides management and monitoring capabilities for a single
Nutanix cluster. Prism Element has a Health dashboard that shows the status of various
components and services in the cluster, such as disks, nodes, CVMs, NCC, and alerts. The Health
dashboard also allows the administrator to run NCC checks manually by using the Actions drop-
down menu on the right side of the screen. The administrator can choose to run all NCC checks
or specific checks based on the category or severity. The NCC checks will run in the background
and generate a report that can be viewed or downloaded from the Summary tab. This method is
easier and faster than running NCC from the command line on the CVM.
NCC stands for Nutanix Cluster Check, which is a framework of scripts that performs system
checks and validations on Nutanix clusters. NCC can detect issues related to hardware, software,
configuration, hypervisor, networking, and more. NCC can be run from the command line
interface (CLI) of any CVM in the cluster by using the ncc command. To run all NCC checks
manually, the administrator can use the command ncc health_checks run_all, which will execute
all available checks and display the results on the screen. This method is more comprehensive
and detailed than running NCC from Prism Element.

Question: 19
A newly-hired Nutanix administrator was tasked by the CIO to create a single VM on a test
network. The network administrator stated that a native VLAN was used on the Cisco TOR
switches with the following parameters:
IP address:172,16.1.2
Network Mask: 255.255.255.0

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Default gateway: 172.16.1.1
VLAN:1
The same parameters were used to create a network profile on Nutanix, but the when the VM
was on …
What should the Nutanix administrator do to fix this issue?

A. Nutanix removed support for native VLAN.

B. Change VLAN field from vlan. 1 to vlan.0.
C. Enable IPv6 on the VM.
D. Use DHCP as opposed to static IP

Answer: B
Explanation:
A native VLAN is a VLAN that is assigned to untagged traffic on a trunk port of a switch. A trunk
port can carry traffic from multiple VLANs, but it needs to have a native VLAN to handle traffic
that does not have a VLAN tag. The native VLAN is usually VLAN 1 by default on most switches,
but it can be changed to any other VLAN number2. When creating a network profile on Nutanix,
the administrator needs to specify the VLAN ID that matches the VLAN configuration on the
physical switch. However, if the network profile uses the same VLAN ID as the native VLAN on
the switch, it will cause network connectivity issues for the VMs connected to that network
profile. This is because Nutanix AHV uses 802.1Q tagging for all network traffic, including traffic
in the native VLAN. The switch will expect untagged traffic in the native VLAN and will drop any
tagged traffic in that VLAN3. To fix this issue, the administrator needs to change the VLAN field
from vlan. 1 to vlan. 0 in the network profile on Nutanix. This will tell Nutanix AHV to send
untagged traffic for that network profile and match the native VLAN configuration on the
switch4.

Question: 20
An administrator needs to provide access for a user to view real-time performance metric for all
VMs on all clusters across the datacenter.
Which method accomplishes this with the least effort and ongoing maintenance?

A. Configure IDP authentication and assign the user to the Cluster Admin role in Prism Central.
B. Configure AD authentication and assign the user to the Viewer role in Prism Element.
C. Configure AD authentication create a custom role, assign the user to the role, and apply the
role to all clusters and VMs

Answer: C
Explanation:
The best method to provide access for a user to view real-time performance metrics for all VMs
on all clusters across the datacenter is to configure AD authentication create a custom role,

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
assign the user to the role, and apply the role to all clusters and VMs. This method accomplishes
this with the least effort and ongoing maintenance because:
AD authentication allows Nutanix Prism Central to integrate with an existing Active Directory
(AD) domain and use AD users and groups for authentication and authorization5. This simplifies
user management and avoids creating local users on Prism Central.
Creating a custom role allows Nutanix Prism Central to define granular permissions for different
actions and entities based on specific needs6. This ensures that users only have access to what
they need and nothing more.
Assigning the user to the custom role allows Nutanix Prism Central to grant access rights for that
user based on the role definition7. This avoids assigning permissions individually for each user.
Applying the role to all clusters and VMs allows Nutanix Prism Central to propagate the access
rights for that role across all entities in scope8. This ensures that users can view real-time
performance metrics for all VMs on all clusters without having to configure each entity
separately.

Question: 21
When a configuring a syslog server in Prism Central, what two pieces information are required?
(Choose two.)

A. HTTPS URL
B. Encryption secret
C. Transport protocol
D. IP address/port

Answer: C, D
Explanation:
According to the Nutanix Prism Central Guide, to configure a syslog server in Prism Central, you
need to specify the transport protocol (TCP or UDP) and the IP address/port of the syslog server.

Question: 22

Question: 23
An administrator is tasked with configuring network on an AHV cluster and wants to maximize
throughput for the host with many small VMs while minimizing network switch configuration.
Which bond mode should the administrator select?

A. Active-active
B. Active-Active with Mac Pinning
C. Active-Backup
D. No-Uplink Bond

Answer: A
Explanation:
According to the Nutanix AHV Networking Guide, active-active bond mode provides load
balancing and fault tolerance for network traffic by distributing packets across multiple
interfaces using a hashing algorithm based on source and destination MAC addresses, IP
addresses, and TCP/UDP ports. This mode does not require any special configuration on the
network switch and can improve throughput for hosts with many small VMs.

Question: 24
Which component is supported by Prism Central storage policies?

A. Virtual Machines
B. Volume Groups
C. VM Templates
D. Storage Containers

Answer: A
Explanation:
According to the Nutanix Prism Central Guide, Prism Central allows you to apply storage policies
on a per VM basis using Category, so that the VM uses the storage configuration defined in the
storage policy. Using a storage policy, you can manage parameters of VMs, such as encryption,
type of or lack of data compression, and IOPS or Throughput throttling values to be applied to
the entities.

 Question: 25
An administrator would like to leverage the Reliable Event Logging Protocol (RELP) with their
Remote Syslog Server. After completing the configuration, it is observed that RELP logging is not
working as expected.
What is the likely cause of this issue?

A. The cluster does not have RELP installed.

B. The GENESIS was the only one chosen to forward log information.
C. The Remote Syslog Server was configure using TCP as the protocol.
D. The remote server does not have rsyslog-relp installed.

Answer: D
Explanation:
According to the Red Hat Customer Portal, to use RELP with Rsyslog, you need to install the
rsyslog-relp package on both the server and the client. If the remote server does not have
rsyslog-relp installed, RELP logging will not work as expected.

Question: 26
Which two predefined views can be added to a report to identify inefficient VMs?

A. Underprovisioned VMs List

B. Zombie VMs List
C. Constrained VMs List
D. Overprovisioned VMs List

Answer: B, D
Explanation:
Zombie VMs and overprovisioned VMs are two types of inefficient VMs that can waste
resources and increase costs in a Nutanix environment. Zombie VMs are VMs that are powered
on but have no activity or utilization for a long period of time. Overprovisioned VMs are VMs
that have more resources allocated than they actually need or use. Both types of VMs can be
identified by adding predefined views to a report in Prism Central.
A predefined view is a template that defines what data is displayed and how that data is
represented in a report. Prism Central provides several predefined views for different purposes,
such as capacity planning, performance analysis, anomaly detection, and efficiency
optimization. To add a predefined view to a report, go to Operations > Reports > New Report
and select the desired view from the list1.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
The Zombie VMs List view shows the list of zombie VMs in the environment based on the CPU
usage, memory usage, disk IOPS, and network throughput metrics. The view also shows the
amount of resources wasted by these VMs and the potential savings that can be achieved by
deleting or resizing them2.
The Overprovisioned VMs List view shows the list of overprovisioned VMs in the environment
based on the CPU usage, memory usage, disk IOPS, and network throughput metrics. The view
also shows the amount of resources wasted by these VMs and the potential savings that can be
achieved by resizing them3.
By adding these two views to a report, an administrator can identify inefficient VMs and take
appropriate actions to optimize resource utilization and reduce costs.

Question: 27
When a VM is connected to a Nutanix managed network, when is the IP addressed assigned?

A. When the vNIC is created on the VM.

B. When the VM is powered on.
C. When the guest OS sends a DHCP request.
D. When the guest OS receives a DHCP acknowledge.

Answer: B
Explanation:
When a VM is connected to a Nutanix managed network, the IP address is assigned when the
VM is powered on. A Nutanix managed network is a network that is created and managed by
Prism Central using IP address management (IPAM). IPAM allows Prism Central to automatically
assign IP addresses to VMs from a pool of available addresses in a subnet. IPAM also tracks the
IP address usage and availability across clusters and networks4.
When a VM is connected to a Nutanix managed network, the administrator can choose one of
the following assignment types for the IP address:
Assign Static IP: This option allows the administrator to manually specify a static IP address for
the VM from the subnet range. The IP address will not change unless the administrator changes
it.
Assign with DHCP: This option allows Prism Central to dynamically assign an IP address for the
VM from the subnet range using DHCP. The IP address may change depending on the DHCP
lease time and availability.
No Private IP: This option allows the administrator to skip assigning an IP address for the
VM. This option is useful for scenarios where the administrator wants to use an external IPAM
solution or assign an IP address later5.
Regardless of the assignment type, the IP address is assigned when the VM is powered on. This
is because Prism Central needs to communicate with the hypervisor (AHV or ESXi) to configure
the virtual NIC (vNIC) of the VM with the IP address information. This communication can only
happen when the VM is in a powered on state6.

 Question: 28
Which two capabilities does IPAM provide in a Nutanix networking configuration? (Choose two.)

A. Allows proxy server settings to be set up for a defined network

B. Allows AHV to assign IP addresses automatically to VMs using DHCP
C. Configures a VLAN with an IP subnet and assigns a group of IP addresses
D. Configures firewall rules to prevent or allow certain TCP/IP traffic

Answer: B, C
Explanation:
According to the Nutanix Support & Insights, IPAM enables AHV to assign IP addresses
automatically to VMs using DHCP. You can configure each virtual network and associated VLAN
with a specific IP subnet, associated domain settings, and group of IP address pools available for
assignment.

Question: 29
Which method can be used to migrate a VM configured for UEFI-boot from a Nutanix Hyper-V
cluster to AHV?

A. Live Migration
B. Storage vMotion
C. Nutanix Move
D. Cloud Connect

Answer: C
Explanation:
Nutanix Move is a tool that allows you to migrate VMs from different sources to Nutanix AHV
with minimal downtime and complexity. Nutanix Move supports migration from Hyper-V to
AHV, including VMs configured for UEFI-boot. UEFI stands for Unified Extensible Firmware
Interface, which is a standard for the software interface between the operating system and the
firmware. UEFI-boot is a mode of booting that uses UEFI instead of BIOS (Basic Input/Output
System) to load the operating system. UEFI-boot offers some advantages over BIOS-boot, such
as faster boot time, larger disk support, and better security features1.
To migrate a VM configured for UEFI-boot from a Nutanix Hyper-V cluster to AHV, you need to
use Nutanix Move and follow these steps2:
Download and deploy the Nutanix Move appliance on the AHV cluster.
Log in to the Nutanix Move web console and add the source Hyper-V environment and the
target AHV environment.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Create a migration plan and select the VMs that you want to migrate. You can choose either
automatic or manual preparation mode for the migration.
Start the migration plan and monitor the progress. The migration plan will perform data
seeding, which is the process of copying the VM data from the source to the target in the
background.
When the data seeding is complete, perform a cutover, which is the process of shutting down
the source VMs and powering on the target VMs. The cutover will also configure the boot device
for the UEFI-boot VMs on AHV.
Verify that the migrated VMs are working as expected on AHV.

Question: 30
An administrator needs to report on any alerts generated by a Nutanix cluster that affected the

In Files, how many FSVMs are deployed by default?

A. 1
B. 2
C. 3
D. 5

Answer: C
Explanation:
According to the Nutanix Files Guide, Nutanix Files instances are composed of a set of VMs
(called FSVMs). Files requires at least three FSVMs running on three nodes to satisfy a quorum
for high availability. By default, Files deploys three FSVMs when you create a file server instance.

Question: 33
A two-node ROBO cluster is configured with a witness VM.

What happens when Node A goes down?

A. The- cluster becomes unavailable and goes into read-only mode.

B. All operations and services on the Node B are shut down and go into a waiting state.
C. The cluster is unaffected and no administrator intervention is required.
D. Node B sends a leadership request to the Witness VM and goes into single-node mode.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: D
Explanation:
According to the Nutanix Support & Insights, in a two-node ROBO cluster with a witness VM, if
one node goes down, the other node sends a leadership request to the witness VM and goes
into single-node mode. The cluster remains available and can tolerate another failure of either
the witness VM or the network link.

Question: 34
How will an HDD failure affect VMs with data on the failed device?

A. The VMs will crash, and will be restarted once the failed HDD has been replaced and the data
has been restored.
B. A live migration will be initiated, moving the affected VMs to a host that contains the replica
data.
C. The VMs will remain operational on that host and continue to function normally with no
noticeable impact
D. An HA event will occur, causing the affected VMs to restart on a node that contains the
replica data.

Answer: D
Explanation:
According to the Troubleshooting hosted disk I/O performance problems (1008885), when using
VMware hosted products, consider that both the virtual machines and host operating system
often share the same disk resources and hardware. If a hard disk fails, the virtual machines that
have data on the failed device will experience an HA event, causing them to restart on a node
that contains the replica data.

Which three cluster operations require an administrator to reclaim licenses?(Choose three)

A. Destroy a cluster.
B. Upgrade a cluster
C. Migrate a cluster
D. Remove a Node from a cluster
E. Move Nodes between clusters.

Answer: A, D, E
Explanation:
https://portal.nutanix.com/page/documents/details/?targetId=Web_Console_Guide-
Prism_v4_7:lic_licensing_managing_c.html
Reclaiming Licenses (Including License Renewal)
You can reclaim and optionally re-apply licenses for nodes in your clusters:
You must reclaim licenses when you plan to destroy a cluster. First reclaim the licenses, then
destroy the cluster. You do not need to reclaim Starter licenses. These licenses are automatically
applied whenever you create a cluster, including after you have destroyed a cluster.
Return licenses to your inventory when you remove one or more nodes from a cluster. Also, if
you move nodes from one cluster to another, first reclaim the licenses, move the nodes, then
re-apply the licenses.
You can reclaim licenses for nodes in your clusters in cases where you want to make
modifications or downgrade licenses. For example, applying an Ultimate license to all nodes in a
cluster where some nodes are currently licensed as Pro and some nodes are licensed as
Ultimate. You might also want to transition nodes from Ultimate to Pro licensing.
You must reclaim licenses when you renew licenses. First reclaim the expired licenses, then
apply new licenses.

A node with Erasure Coding fails.
What is the impact?

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A. The node stops utilizing Erasure Coding.
B. Potentially increased amount of data stored in the SSD tier.
C. Increased Controller VM CPU Load.
D. AQS unable to do deduplication during the Erasure Coding failure.

Answer: B
Explanation:
When a node with Erasure Coding fails, the cluster will automatically rebuild the missing data
using replication factor (RF) 2 or 3, depending on the cluster configuration. This means that the
data that was previously stored using Erasure Coding will now be stored using full copies, which
may increase the amount of data stored in the SSD tier1.

Question: 44
A customer wants to isolate a group of VMs within their Nutanix environment for security
reasons. The customer creates a VM with two NICs to act as a firewall and installs the
appropriate software and certificates.
However, no one from the outside can access the application.
What is the likely cause of this problem?

A. A shared volume group must be used by all isolated VMs

B. More than one NIC cannot be added to a VM
C. One of the NICs needs to be configured on the internal VLAN
D. Wireshark is installed on the NAT VM

Answer: C
Explanation:
One of the NICs needs to be configured on the internal VLAN. This is because the VMs that are
isolated need to communicate with the firewall VM through a private network, and the firewall
VM needs to communicate with the external network through a public network. The internal
VLAN is a logical network that can be created and managed by AHV1. If the firewall VM does not
have a NIC on the internal VLAN, it will not be able to route traffic between the isolated VMs
and the outside world.

Question: 45
Which two methods are available when migrating a VM from a legacy 3-tier solution using
VMware ESXi to AHV? (Choose two.)

A. Deploy the Move appliance.

B. Use Cross-Hypervisor DR.
C. Import the .vmdk into the Image Service.
D. Use shared nothing live migration.

Answer: A, C
Explanation:
Deploy the Move appliance and Import the .vmdk into the Image Service. These are two
methods that can be used to migrate a VM from VMware ESXi to AHV2. The Move appliance is a
tool that automates the migration process by converting the VM disks and configuration to AHV
format and transferring them to the Nutanix cluster3. The Image Service is a feature that allows
users to upload and manage disk images that can be used to create or clone VMs on AHV4. By

VM from that image.

Question: 46
A customer has a 24-node cluster with all containers configured with RF3. Two different nodes
have incurred a simultaneous HDD failure.
What is the result?

A. The cluster runs in a degraded state until the failed drives are replaced and the data has been
restored to three replicas.
B. Sixty minutes after the failures a rebuild of the lost data can remaining HDDs begins to restore
to three replicas.
C. The VMs with data on those drives crash, and an HA event occurs, restarting them on a
remaining healthy node.
D. The Nutanix cluster recognizes the failures and immediately begins to rebuild lost data to
three replicas.

Answer: D
Explanation:
This is because Nutanix uses a distributed storage fabric (DSF) that replicates data across
multiple nodes and drives to ensure data resiliency. When a drive fails, the cluster detects the
failure and initiates a data rebuild process to restore the replication factor (RF) of the affected
containers. The data rebuild process does not affect the availability or performance of the VMs,
as they can still access their data from other replicas on other nodes or drives. Therefore, there
is no need to wait for 60 minutes, use a shared volume group, or trigger an HA event.

In which two scenarios is an automated live migration likely to occur? (Choose two)

A. Cluster resource hotspot

B. AOS upgrade
C. Network upgrade
D. Hypervisor upgrade

Answer: A, B
Explanation:
Automated live migration is a feature of Nutanix that allows the cluster to automatically move
VMs from one host to another without any downtime, in order to optimize the performance and
availability of the cluster. According to the Nutanix documentation1, automated live migration
can occur in the following scenarios:
Cluster resource hotspot: When a host or a group of hosts experience high resource utilization,
such as CPU, memory, or network, the cluster can automatically migrate some VMs to other
hosts with lower utilization, in order to balance the load and avoid performance degradation.
AOS upgrade: When upgrading the Nutanix software (AOS), the cluster can automatically
migrate the VMs from the host that is being upgraded to another host in the same availability
zone, in order to maintain the VM availability and minimize the impact of the upgrade process.
AHV host maintenance mode: When putting an AHV host into maintenance mode, the cluster
can automatically migrate all the VMs from that host to another host in the same availability
zone, in order to prepare the host for maintenance operations such as hardware replacement or
firmware update.

An administrator is reviewing performance of a core banking system that routinely has 20,000
concurrent users. During, business hours, the CPU on the applications servers runs at close to
100%. The administrator needs to determine if there is a performance issue specific to the app
servers, the database servers, or all servers on the cluster.

Which metrics should the administrator review in Prism Analysis Graphs?

A. Cluster IO, Network, Database and App Server CPU

B. Cluster CPU and Memory Only
C. Cluster IO, CPU, Memory and Database and App Server CPU
D. Cluster IO, CPU, Memory, Network, App Server CPU

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: D
Explanation:
In this case, the administrator wants to investigate the performance of a core banking system
that consists of application servers and database servers. The application servers have high CPU
utilization during business hours, which may indicate a bottleneck or a resource contention
issue. The administrator needs to review multiple metrics in Prism Analysis Graphs to identify
the root cause and determine if there is a problem with the app servers only, or with other
components as well.
The metrics that are relevant for this analysis are:
Cluster IO: This metric shows the input/output operations per second (IOPS) and throughput
(MBps) of the cluster. It can help to understand if there is a high demand for disk IO from the
VMs or if there is any latency or congestion in the storage layer.
Cluster CPU: This metric shows the CPU utilization (%) and load average of the cluster. It can
help to understand if there is enough CPU capacity in the cluster to handle the workload or if
there is any imbalance or contention among hosts.
Cluster Memory: This metric shows the memory utilization (%) and available memory (GB) of the
cluster. It can help to understand if there is enough memory capacity in the cluster to support
the VMs or if there is any pressure or swapping in the memory layer.
Network: This metric shows the network throughput (MBps) and packets per second (pps) of the
cluster. It can help to understand if there is enough network bandwidth in the cluster to transfer
data between hosts and VMs or if there is any congestion or packet loss in the network layer.
App Server CPU: This metric shows the CPU utilization (%) and load average of each application
server VM. It can help to understand if there is any variation or anomaly in the performance of
each app server or if there is any correlation with other metrics.
Database Server CPU: This metric shows the CPU utilization (%) and load average of each
database server VM. It can help to understand if there is any variation or anomaly in the
performance of each database server or if there is any correlation with other metrics.

Question: 58
A VM in a 12-node Nutanix cluster is hosting an application that has specific Physical GPU
requirements. Only three nodes in the cluster meet this requirement.
The administrator wants to allow a general workload to be distributed across all nodes in the
cluster and must make sure that the node hosting the VM meets its requirements.
How should the administrator perform this task?

A. Create a sperate three-node cluster using the nodes that meet the requirement.
B. Configure VM-Host affinity for the nodes that meet the application's GPU requirement.
C. Over-Provision the application VM with additional virtual GPUs.
D. Configure anti-affinity rules between the application VM and the other VMs running on the
cluster.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: B
Explanation:
Configure VM-Host affinity for the nodes that meet the application’s GPU requirement. This is
because VM-Host affinity allows the administrator to specify which nodes a VM can run on or
must not run on1. By creating a VM-Host affinity rule that binds the application VM to the three
nodes that have the physical GPU, the administrator can ensure that the VM will always run on a
node that meets its requirement, regardless of any HA or migration events. This also allows the
other nodes in the cluster to host other VMs without any restrictions.

Question: 59
Where should an administrator unregister Prism Element from Prism Central?

A. From a Host SSH session

B. From the Prism Central web console
C. From the Prism Element web console
D. From a CVM SSH session

Answer: A
Explanation:
This is because there is no GUI method to unregister a cluster from Prism Central, so the process
requires SSH access to the PC VM as well as to a CVM of the cluster2. The unregistration process
involves getting the UUID of the cluster from the CVM and then using that to trigger de-
registration from PC command line2. The unregistration process also involves cleaning up any
associated metadata and configuration on both PC and PE2. Therefore, the administrator needs
to use a Host SSH session to perform this task.

What is the expected operation during node addition when the new node has a different AOS
version?

A. The entire cluster is upgraded to the latest one-click release.

B. The node is added and a separate upgrade operation must be performed.
C. The addition fails and forces the administrator to image using standalone Foundation.
D. The node is automatically re-imaged using the software currently running in the cluster.

Answer: D
Explanation:
The node is automatically re-imaged using the software currently running in the cluster. This is
because Nutanix supports a feature called Auto Re-Image that allows adding nodes with
different AOS versions to an existing cluster without manual intervention. The Auto Re-Image
feature detects the AOS version mismatch and automatically downloads and installs the same

Question: 69
A Nutanix cluster is equipped with four nodes. Four VMs on this cluster have been configured
with a VM-VM anti-affinity policy and are each being hosted by a different node.
What occurs to the cluster and these VMs during an AHV upgrade?

A. One node hosts two VMs while the node being upgraded is in maintenance mode.
B. One VM out of the four powers down when the node hosting it reboots.
C. The AHV pre-upgrade checks fail until the administrator disables the anti-affinity policy.
D. The AHV pre-upgrade checks fail until the four VMs are powered off.

Answer: A
Explanation:
One node hosts two VMs while the node being upgraded is in maintenance mode. This is
because Nutanix supports a feature called Rolling Upgrade that allows upgrading AHV on a
cluster without any downtime or impact to the VMs. The Rolling Upgrade feature performs the
upgrade one node at a time, by putting the node in maintenance mode, evacuating the VMs to
other nodes, upgrading AHV, and then bringing the node back online. The VM-VM anti-affinity
policy ensures that the four VMs are not placed on the same node during the evacuation
process, so one node will host two VMs temporarily while the other node is being upgraded.

Question: 70
How many SSL certificates are used by Prism Element on a Nutanix cluster?

A. 1
B. 5
C. 256
D. 2048

Answer: A
Explanation:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
According to the Nutanix Prism Element Guide, Prism Element uses a single SSL certificate on a
Nutanix cluster. The certificate is used to secure the communication between the web browser
and the Prism web console. The certificate is also used to authenticate the cluster to external
services, such as Active Directory, SMTP, and SNMP. The certificate can be either self-signed or
signed by a trusted certificate authority (CA). The certificate can be replaced or renewed
through the Prism web console or the ncli command-line interface.

Question: 71
Which algorithm do snapshots and clones leverage to maximize efficiency and effectiveness?

A. Continuous Data Protection

B. Copy-on-Write
C. Split-mirror
D. Redirect-On-Write

Answer: B
Explanation:
According to the Dell Unity: Data Reduction Technical White Paper1, snapshots and clones on
Dell Unity use the Copy-on-Write (CoW) algorithm to maximize efficiency and effectiveness.
CoW is a technique that defers the copying of data until it is modified. This means that
snapshots and clones only consume space when changes are made to the source or the clone,
respectively. CoW also preserves the original data in case of a rollback or recovery operation.

What are two minimum prerequisites for live migration to succeed? (Choose two.)

A. All AHV hosts have IP addresses in the same subnet

B. All AHV hosts must be configured on the same VLAN
C. All VMs have an IP address in the same subnet
D. All VMs are configured for the same VLAN

Answer: A, D
Explanation:
According to section 5 of the exam blueprint guide1, one of the topics covered is live migration.
Live migration is the process of moving a running VM from one host to another without any
downtime or interruption of service. To perform live migration, there are some prerequisites
that must be met, such as:
All AHV hosts have IP addresses in the same subnet
All VMs are configured for the same VLAN
The source and destination hosts have enough resources to accommodate the VM
The VM does not have any PCI devices attached

Question: 74
When creating a VM on an AHV cluster, how is the initial placement of the VM determined?

A. AHV uses a round robin algorithm, placing new VMs onto hosts based on the numerical order
of their UUID
B. The administrator right clicks on the desired host and selects Power on VM from the
dropdown menu
C. The Acropolis Dynamic Scheduler selects a host which provides adequate resources for the
VMs configuration
D. Placement is determined by the host that holds the new_VM token at the time of VM
creation

Answer: C
Explanation:
According to section 6 of the exam blueprint guide1, one of the topics covered is VM placement
options. When creating a new VM on an AHV cluster, there are two ways to determine its initial
placement:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Automatic placement: The Acropolis Dynamic Scheduler (ADS) selects a host that provides
adequate resources for the VM’s configuration, such as CPU, memory, disk space, and network
bandwidth. ADS also considers factors such as host load, power state, availability domains, and
affinity rules.
Manual placement: The administrator can specify a host or a host group where they want to
place the VM.

Question: 75
Which command should an administrator run from the CLI to view the uplink state of all AHV
nodes in the
cluster?

A. allssh show_uplinks
B. manage_ovs show_uplinks
C. allssh manage_ovs show_uplinks
D. manage ovs show uplinks

Answer: C
Explanation:
According to section 4 of the exam blueprint guide1, one of the topics covered is AHV
networking components and configuration settings. One of these components is Open vSwitch
(OVS), which is a software switch that provides network connectivity between VMs and physical
networks. OVS has two types of ports:
Uplink ports: These are physical ports that connect to external networks or switches.
Internal ports: These are virtual ports that connect to VMs or other internal networks.
To view the uplink state of all AHV nodes in the cluster, an administrator can use the
manage_ovs command with the show_uplinks option. This command displays information such
as port name, link state, speed, duplex mode, MTU size, bond mode, and bond status. However,
this command only works on a single node. To run the command on all nodes in the cluster, an
administrator can use the allssh command, which executes a command on all CVMs in parallel.
Therefore, the correct command is:
allssh manage_ovs show_uplinks

A. Multi-cluster network configuration

B. Container creation
C. Multi-cluster Single Sign On

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
D. Data reduction configuration

Answer: C
Explanation:
According to the web search results, Prism Central is a multi-cluster manager that provides a
single, centralized management interface for Nutanix environments12. One of the features of
Prism Central is multi-cluster Single Sign On (SSO), which allows users to log in once and access
multiple clusters without re-entering credentials3.

Question: 77
Which component ensures uniform distribution of data throughout the cluster to eliminate hot
spots and speed up rebuilds?

A. Cassandra
B. Distributed Storage Fabric
C. High Availability
D. Acropolis App Mobility Fabric

Answer: B
Explanation:
According to the web search results, Distributed Storage Fabric (DSF) is the scale-out storage
technology that makes HCI and cloud possible45. DSF pools the storage devices that are directly
attached to a cluster of servers and presents them to applications across a variety of storage
protocols4. DSF also manages and protects data by a fine-grained, distributed metadata system
that ensures uniform distribution of data throughout the cluster to eliminate hot spots and
speed up rebuilds

Question: 78
An administrator is configuring data protection and DR for a multi-tier application. All VMs must
be protected at the same time.
What must the administrator do to meet this requirement?

A. Create a consistency group for each VM with identical schedules

B. Create a consistency group for the application and place all VMs in it
C. Create a protection domain for the application and select auto-protect related entities
D. Create a protection domain for each VM with identical schedules

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: B
Explanation:
According to the web search results, a consistency group is a group of related applications or
services that must be recovered together in order to work properly, and this means more than
being recovered at the same time67. They also typically need to be recovered to the same point
in time6. Therefore, to meet the requirement of protecting all VMs of a multi-tier application at
the same time, the administrator must create a consistency group for the application and place
all VMs in it8. This way, the administrator can apply data protection policies and schedules to
the entire consistency group as a single unit8.

Question: 79
An administrator logs in to Prism Element goes to the Network view, and sees the output shown
in the exhibit.

Which three steps must the administrator take to increase throughput to the host? (Choose
three.)

A. Connect the 10Gb interfaces to the physical switch.

B. Change the bond mode to balance-slb or balance—tcp.
C. Remove any 1Gb interfaces still connected from the default bond.
D. Add a new switch to the network and connect 1Gb interfaces to it.
E. Change the VLAN ID to a higher priority ID.

Answer: A, B, C
Explanation:
These are the three steps that the administrator must take to increase throughput to the host.
According to the network diagram, the host has two 10Gb interfaces and two 1Gb interfaces in
the default bond, but only one of the 10Gb interfaces is connected to a switch. The other 10Gb
interface is disconnected and has a red “X” on it. The two 1Gb interfaces are also disconnected
and have dotted lines. This means that the host is using only one 10Gb interface for all its
network traffic, which limits its maximum bandwidth to 10 Gbps.
To increase the throughput, the administrator should connect both 10Gb interfaces to the
physical switch, preferably to different switches for redundancy and high availability. This will

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
allow the host to use both 10Gb interfaces for network traffic, which can increase its maximum
bandwidth to 20 Gbps. However, this also requires changing the bond mode from active-backup
to balance-slb or balance-tcp, which are load balancing modes that distribute network traffic
across multiple interfaces based on source MAC address or TCP session1. The default bond
mode of active-backup only uses one interface at a time and switches to another interface only
when the active one fails2.
Finally, the administrator should remove any 1Gb interfaces still connected from the default
bond, as they are not needed and may cause performance issues or conflicts with the load
balancing modes. The 1Gb interfaces can be used for other purposes, such as management or
backup networks, by creating separate bonds or bridges for them3. Alternatively, they can be
left disconnected if they are not required.

Question: 80
AHV IPAM assigns an IP address from the address pool when creating a managed VM NIC.
At which two instances does the address release back to the pool? (Choose two)

A. The IP address lease expires

B. The VM NIC is deleted.
C. The IP address is changed to static.
D. The VM is deleted.

Answer: B, D
Explanation:

Administrators can use Acropolis with IPAM to deliver a complete virtualization deployment,
including network management, from the unified Prism interface. This capability radically
simplifies the traditionally complex network management associated with provisioning VMs and
assigning network addresses. To avoid address overlap, be sure to work with your network team
to reserve a range of addresses for VMs before enabling the IPAM feature.
The Acropolis master assigns an IP address from the address pool when creating a managed VM
NIC; the address releases back to the pool when the VM NIC or VM is deleted.

The Linux Admin role has been created to manage only Linux VMs in the environment. However,
the Admin1 user does not have access to all Linux VMs.
What step should be taken to grant the proper access?

A. Add the hosts to the entities KM for the role.

B. Grant the admin1 user the viewer role (or the cluster.
C. Add the role to the Linux images.
D. Add the proper category to each Linux VM.

Answer: D
Explanation:
According to the Nutanix Prism Central Guide, role-based access control (RBAC) in Prism Central
allows you to create custom roles and assign them to users or groups based on the categories of
the entities they need to manage1. Categories are key-value pairs that you can assign to entities
such as VMs, hosts, clusters, images, etc. to group them logically2. For example, you can create
a category key called “OS” and assign values such as “Linux” or “Windows” to different VMs
based on their operating system.
In the exhibit, the Linux Admin role has been created with the following settings:
The role has the “VM Admin” permission, which allows the user to perform all actions on VMs3.
The role has been assigned to the admin1 user.
The role has been scoped to the entities that have the category key “OS” and the value “Linux”.
However, the admin1 user does not have access to all Linux VMs in the environment. This
means that some of the Linux VMs do not have the proper category assigned to them. To grant
the proper access, the administrator should add the category key “OS” and the value “Linux” to
each Linux VM that needs to be managed by the Linux Admin role. This can be done either
individually or in bulk through Prism Central4. Once the categories are added, the admin1 user
will be able to see and manage all Linux VMs in the environment.

Question: 82
When installing Nutanix Guest Tools (NGT) on an ESXi-hosted VM, which port should be enabled
on the VM to allow communication with the NGT-Controller VM service?

A. 2000
B. 2074
C. 8080
D. 9943

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: D
Explanation:
NGT is a software package that enables advanced VM management features provided by
Nutanix, such as file-level restore, VM mobility, and application-consistent snapshots12. To use
NGT, you need to enable the NGT feature for a VM in the Prism Element web console, mount
the NGT installer (ISO disk file) in the VM, and install NGT in the VM1. However, before installing
NGT, you need to ensure that the VM can communicate with the NGT-Controller VM service,
which runs on the Controller VM (CVM) of each Nutanix node3. The NGT-Controller VM service
listens on port 9943 for incoming requests from the guest VMs3. Therefore, you need to enable
port 9943 on the ESXi-hosted VM to allow communication with the NGT-Controller VM service.

An administrator increases the cluster RF to 3. The containers are not modified.
What will the new values in the data resiliency dashboard be for FAILURES TOLERABLE for the
Zookeeper and Extent Groups components?

A. Zookeeper = 1 and Extent Groups = 1

B. Zookeeper = 2 and Extent Groups = 2
C. Zookeeper = 2 and Extent Groups = 1
D. Zookeeper = 1 and Extent Groups = 2

Answer: C
Explanation:
According to the web search results, the cluster redundancy factor (RF) determines how many
copies of the cluster metadata and configuration data are stored on different nodes. By default,

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
the cluster RF is 2, which means that there are three copies of the Zookeeper and Cassandra
data on the cluster. If the cluster RF is increased to 3, then there will be five copies of the
Zookeeper and Cassandra data on the cluster12. This means that the Zookeeper component can
tolerate two failures, as it can still operate with a quorum of three nodes out of five3.
However, the container replication factor (RF) determines how many copies of the VM data and
oplog are stored on different nodes. The container RF can be set independently for each
container, and it can be different from the cluster RF. For example, a container can have RF 2
even if the cluster has RF 34. In this case, the container will only have two copies of the VM data
and oplog on the cluster, regardless of the cluster RF. This means that the Extent Groups
component can only tolerate one failure, as it needs at least one copy of the VM data and oplog
to be available5.
Therefore, if the administrator increases the cluster RF to 3, but does not modify the containers,
then the new values in the data resiliency dashboard will be Zookeeper = 2 and Extent Groups =
1.

Question: 85
Which three configuration scenarios are valid for the deployment of Prism Central? (Choose
three.)

A. Environments use Network Address Translation.

B. Prism Elements and Prism Central art in different subnets.
C. Environments do not have Internet access.
D. Prism Elements and Prism Central have proxy configured.
E. Environments use the 192.168.5.0/24 CVM management network.

Answer: A, B, C
Explanation:
Prism Central is a multi-cluster manager that provides a single, centralized management
interface for Nutanix environments1. Prism Central can be deployed in different configuration
scenarios, depending on the network and security requirements of the environment. Some of
the valid scenarios are:
Environments use Network Address Translation (NAT): NAT is a method of mapping one IP
address space to another by modifying network address information in IP datagram packet
headers while they are in transit across a traffic routing device2. NAT can be used to enable
communication between Prism Central and Prism Elements that are in different networks or
subnets3. For example, Prism Central can be deployed in a public cloud and use NAT to access
Prism Elements that are in a private data center3.
Prism Elements and Prism Central are in different subnets: A subnet is a logical subdivision of an
IP network that allows multiple networks to share a single physical network4. Prism Elements
and Prism Central can be in different subnets as long as they can communicate with each other
through routing or NAT3. For example, Prism Central can be deployed in a management subnet
and access Prism Elements that are in different application subnets3.

Environments do not have Internet access: Internet access is not required for the deployment of
Prism Central, as long as the environment meets the prerequisites and considerations for
installing or upgrading Prism Central. For example, Prism Central can be deployed in a dark site,
which is an environment that does not have Internet access or has restricted Internet access. In
this case, the administrator needs to manually enable microservices infrastructure and
download the required software packages from another source.

What is the expected behavior of the VMs residing on that host when a controller VM becomes
unavailable?

A. A Live Migration will be performed on the affected VMs.

B. The host will automatically redirect I/O and VMs will continue running.
C. The impacted host and VMs will automatically shut down.
D. VM High Availability will restart the impacted VMs on another host

Answer: B
Explanation:
According to the Nutanix Support & Insights web search result1, if the owner Controller VM
becomes unavailable, the address moves to another Controller VM, ensuring that it is always
available. This IP address is also used as a cluster-wide address by clients configured as part of
Nutanix Files and other products. Therefore, the host will automatically redirect I/O and VMs
will continue running without any interruption.

Question: 89
An administrator wants to have a VM on an AHV cluster with access to multiple VLANs. What is
the most efficient way to achieve this?

A. Update a vNIC on the VM to operate in trunked mode for all desired VLANs.
B. Create a network in AHV associated with all those VLANs on all hosts.
C. Use SFPs that allow the needed VLANs.
D. Use one vNIC per VLAN for the VM.

Answer: A
Explanation:
According to the Nutanix Support & Insights web search result2, VM NICs on AHV can operate in
two modes: Access and Trunked. Access NICs are the default, and allow one VLAN on the NIC.
Trunked NICs allow multiple VLANs on a single NIC for VMs that are VLAN aware. If you must use
trunked NICs, follow the steps described in the web search result2. Therefore, the most efficient
way to have a VM on an AHV cluster with access to multiple VLANs is to update a vNIC on the
VM to operate in trunked mode for all desired VLANs.

 Question: 90
Which two access protocols are supported by Files? (Choose two.)

A. ISCSI
B. SMB
C. FCOE
D. NFS

Answer: B, D
Explanation:
According to the Network File System web search result3, NFS (Network File System) is a
distributed file system protocol that allows a user on a client computer to access files over a
network in a manner similar to how local storage is accessed. NFS is one of the access protocols
supported by Files. According to the [MS-WPO]: File Access Services Protocols web search
result4, SMB (Server Message Block) is a Windows file sharing protocol that enables applications
to discover, access, and share files that are hosted on or made available by a file server, using a
network between them, in a secure and managed environment. SMB is another access protocol
supported by Files. Therefore, SMB and NFS are two access protocols supported by Files.

An administrator is adding a node with a higher AOS release to an existing cluster.
What is the most efficient action an administrator should take to ensure it is in a supported
state?

A. Destroy cluster and foundation with the new node in place

B. Add the node to the cluster and leave the existing AOS version in place
C. Perform standalone reimage of the new node and then add to cluster
D. Add the node to the cluster and reboot all running VMs to use new release

Answer: C
Explanation:
According to the web search results, the most efficient action an administrator should take to
ensure a supported state when adding a node with a higher AOS release to an existing cluster is
to perform a standalone reimage of the new node and then add it to the cluster1. This way, the
new node will have the same AOS version as the existing nodes, and there will be no
compatibility issues or downtime. Therefore, option C is correct, while options A, B, and D are
not.

An administrator is configuring cross-hypervisor DR from an ESXi cluster to a new AHV cluster.
When the administrator migrates a protection domain to the AHV cluster, the VMs fail to boot.
What should the administrator do to correct this problem?

A. Increase the snapshot frequency to more than 6 hours.

B. Uninstall VMware Tools from the VMs.
C. Install Nutanix Guest Tools in the protected VMs.
D. Add all VMs into a single consistency group.

Answer: C
Explanation:
According to the web search results, one of the requirements for cross-hypervisor disaster
recovery (CHDR) is to install and configure Nutanix Guest Tools (NGT) on all the VMs2. NGT
configures the VM with all the required drivers for VM portability. Without NGT, the VMs may
fail to boot after being migrated to a different hypervisor type.

Question: 93
A customer has a newly-deployed AHV cluster with nodes that have 2.x 10 GBE and 2.x
interface. The customer wants to use all available network interfaces to provide connectivity to
the VMs.
Which option should the administrator use to achieve this while remaining consistent with
Nutanix recommendations?

A. Create separate VLANs that map 10GbE and 1GbE interfaces.

B. Createbond1 on virbr0 and add the 1GbE interfaces to it for VM use.
C. Create a second bond on br0 on each host and assign the 1 GbE interfaces to it.
D. Create a second bridge on each host and assign the 1GbE interfaces to it.

Answer: D
Explanation:
According to the web search results, one of the best practices for Nutanix AHV networking is to
create a second bridge on each host and assign the 1GbE interfaces to it3. This way, the
customer can use both 10GbE and 1GbE interfaces for VM traffic, and also benefit from network
isolation and redundancy.

C. Erasure coding
D. Deduplication

Answer: C
Explanation:
According to the Nutanix Support & Insights web search result1, erasure coding is a data savings
technique that utilizes stripes and parity calculation in a Nutanix cluster. Erasure coding
increases the usable capacity on a cluster by reducing the replication factor of data blocks.
Instead of replicating data, erasure coding uses parity information to rebuild data in the event of
a disk or node failure. Erasure coding can save up to 50% of storage space compared to
replication factor 2, and up to 75% compared to replication factor 32.

Question: 97
The administrator wants a container to be displayed and limited to 1TB in the hypervisor.
What advanced container setting must the administrator set?

A. Advertised Capacity
B. Reserved Capacity
C. Advertised Quota
D. Reserved Quota

Answer: A
Explanation:
According to the Nutanix Support & Insights web search result3, advertised capacity is an
advanced container setting that allows the administrator to reserve an advertised storage space
for a storage container. An advertised capacity setting gives the hypervisor a maximum storage
size that the storage container can use. This setting can be any arbitrary value greater than or
equal to the resiliency required. The hypervisor ensures that the storage container storage
doesn’t go beyond the advertised capacity. If the administrator wants a container to be
displayed and limited to 1TB in the hypervisor, they should set the advertised capacity to 1TB.

The customer is seeing high memory utilization on a mission critical VM. Users report that the
application is unavailable. The guest OS does not support hot add components.
How should the administrator fix this issue?

A. Access the CVM on the host that is running the VM:

B. From the Prism web console:
C. Go to Control Panel in the VM:
D. During the next maintenance window:

Answer: B
Explanation:
The best way to fix this issue is to increase the amount of memory assigned to the VM from the
Prism web console. This option allows the administrator to modify the VM configuration without
accessing the CVM or shutting down the VM. The Prism web console provides a simple and
intuitive interface for managing Nutanix clusters and VMs1. To change the memory allocation
for a VM, the administrator can follow these steps2:
Go to the VM dashboard
Select the VM from the VMs list
Choose Update
Adjust the amount of memory assigned to the VM
Click Save

A. One per availability zone

B. One per customer environment
C. One per physical site
D. One per AHV cluster

Answer: B

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Explanation:
The number of Prism Central instances required to deploy Leap is one per customer
environment. Prism Central is a multi-cluster manager that provides a single, centralized
management interface for Nutanix environments3. Leap is a native cloud extension that
provides disaster recovery as a service (DRaaS) for Nutanix environments4. To use Leap,
customers need to have one Prism Central instance deployed in their primary site, and register it
with their Xi Cloud Services account5. This Prism Central instance can manage multiple Nutanix
clusters across different physical sites or availability zones6.

Question: 102
What requires iSCSI initiator configuration in the guest OS to use Volumes?

A. SQL Server Always On Availability Group

B. Microsoft Windows Failover Cluster
C. Oracle RAC
D. Exchange DAG

Answer: B
Explanation:
The only option that requires iSCSI initiator configuration in the guest OS to use Volumes is
Microsoft Windows Failover Cluster. Volumes is an enterprise-class, software-defined block
storage solution that exposes storage resources directly to virtualized guest operating systems
or physical hosts using the iSCSI protocol7. To use Volumes, customers need to configure iSCSI
initiators on their hosts or guest OSes. However, some applications or services can use native
storage adapters instead of iSCSI initiators when running on AHV VMs. These include:
SQL Server Always On Availability Group: This is a high availability and disaster recovery solution
for SQL Server databases that uses Windows Server Failover Clustering (WSFC) and Availability
Groups (AGs) as its core components. When running on AHV VMs, SQL Server Always On
Availability Group can use native storage adapters instead of iSCSI initiators.
Oracle RAC: This is a clustered database system that provides high availability and scalability for
Oracle databases. When running on AHV VMs, Oracle RAC can use native storage adapters
instead of iSCSI initiators.
Exchange DAG: This is a group of up to 16 mailbox servers that hosts a set of databases and
provides automatic database-level recovery from failures that affect individual servers or
databases. When running on AHV VMs, Exchange DAG can use native storage adapters instead
of iSCSI initiators.

Question: 103
What is the name of the internal bridge used by AHV nodes and CVMs?

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A. vnet0
B. br1
C. br0
D. virbr0

Answer: C
Explanation:
According to the Nutanix Support & Insights web search result1, the name of the internal bridge
used by AHV nodes and CVMs is br0. The internal bridge is an Open vSwitch (OVS) bridge that
connects the AHV host management interface, the CVM interface, and the VM vNICs. The
internal bridge also acts as a gateway for the CVM and VM traffic to reach the external network
through the host physical NICs.

Question: 104
An administrator adds a node with older generation processors to an existing AHV cluster with
newer generation processors. What is the effect on live migration?

A. Live migration continues to function as expected and VMs can move to any AHV host.
B. Live migration is prevented until the administrator enables the legacy migration option.
C. Live migration is prevented until the administrator manually changes the newer processor
level.
D. Live migration of VMs is prevented between newer and older processors.

Answer: D
Explanation:
According to the Migration to a different processor web search result2, live migration of VMs
depends on the source and destination hosts having the same CPU functions (CPU flags). Live
migration requires the source and destination hosts to have CPUs from the same manufacturer,
and only CPU functions which both hosts support are provided (same CPU generation, or by
using VMware Enhanced vMotion Compatibility (EVC)). If the administrator adds a node with
older generation processors to an existing AHV cluster with newer generation processors, then
live migration of VMs is prevented between newer and older processors, unless EVC is enabled.

Question: 105
An administrator needs to bring down a host in a Nutanix Cluster for maintenance reasons. The
administrator puts the host in maintenance mode.
What should the administrator do to perform an orderly shutdown of the CVM?

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A. Execute the cvm_shutdown -P new command from the CVM.
B. Enter Fever off Server - immediate from the IPMI console.
C. Enter Fewer off Server-orderly Shutdown from the IPMI console.
D. Execute the cvm_shutdown -P now command from the host.

Answer: A
Explanation:
According to the How to use the cvm_shutdown script web search result3, the cvm_shutdown
script signals HA when shutting down the CVM (Controller VM) to forward the storage traffic to
another healthy CVM. Instead of using sudo shutdown or sudo reboot commands, this script
should be used to minimize I/O hits in user VMs running on the present hypervisor host. The
cvm_shutdown -P now command will initiate the shutdown process on the CVM immediately.
Therefore, if the administrator needs to perform an orderly shutdown of the CVM, they should
execute this command from the CVM.

Question: 106
The Stargate service becomes unavailable on a single CVM on an AHV node. What is used to
maintain I/O operations in the cluster?

A. Route injection
B. iSCSl redirector
C. Hypervisor HA
D. ha.py

Answer: A
Explanation:
According to the Nutanix Support & Insights web search result1, route injection is used to
maintain I/O operations in the cluster when the Stargate service becomes unavailable on a
single CVM on an AHV node. Route injection is a mechanism that allows the CVMs to
communicate with each other and redirect the I/O requests to another healthy CVM in the
cluster. Route injection uses the Linux kernel routing table to add or delete routes dynamically,
based on the availability of the Stargate service on each CVM.

Question: 107
An administrator notices that most of the VMs in the cluster are on one host. Users report that
an application seems to respond slowly. The application server VM has significantly more
memory assigned to it than other VMs.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
How should the administrator fix this issue?

A. Reduce the amount of memory assigned to the VM.

B. Migrate the VM to a different host.
C. Add more memory to the VM.
D. Increase the memory on the CVM.

Answer: A
Explanation:
According to the Troubleshoot high memory issues on Azure virtual machines web search
result2, one of the common factors in a low memory situation is over-provisioning memory for a
VM. Over-provisioning memory can cause memory pressure, which leads to swapping and
degraded performance. Therefore, to fix this issue, the administrator should reduce the amount
of memory assigned to the VM, based on the average hardware requirements for that operating
system and application load.

Question: 108
A vDisk is read by multiple VMs. The cluster creates immutable copies of the vDisk. What are
these vDisk copies called?

A. Disk Clones
B. Golden Images
C. Volume Groups
D. Shadow Clones

Answer: D
Explanation:
According to the Nutanix Support & Insights web search result3, shadow clones are vDisk copies
that are created by the cluster when a vDisk is read by multiple VMs. Shadow clones are
immutable copies of a vDisk that are stored in different nodes in the cluster, and are used to
improve read performance and reduce network traffic. Shadow clones are automatically created
and deleted by the cluster, based on the demand and availability of resources.

Question: 109
Which node type does not deploy a Nutanix Controller VM?

A. Storage Only
B. Hyper Converged

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
C. Compute Only
D. All Flash

Answer: C
Explanation:
A Compute Only node is a node that does not have any local storage devices and only provides
compute resources to the cluster2. A Compute Only node does not run a CVM, but instead relies
on the CVMs of other nodes to access the distributed storage fabric2

Question: 110
Refer to the exhibit.

System Non-Root Partition Usage shows a warning or critical alert The administrator needs to
change the frequency of checks and alerts to respond more quickly.
Where in Prism Element should the administrator change the frequency of checks and alerts?

A. Health Dashboard > Manage Crocks > Frequency

B. Alerts Dashboard > Manage Checks > Schedule
C. Health Dashboard > Manage Checks > Schedule
D. Alerts Dashboard > Manage Checks > Frequency

Answer: C
Explanation:
According to the Nutanix Support & Insights web search result1, the administrator can change
the frequency of checks and alerts for the System Non-Root Partition Usage in Prism Element by
going to the Health Dashboard > Manage Checks > Schedule. The administrator can select the
check name, such as disk_usage_check, and click on Edit Schedule. The administrator can then
choose the desired frequency, such as every 15 minutes, every hour, or every day, and click on
Save. This will change how often the check runs and alerts are generated.

 Question: 111
An administrator migrates a VM onto a new Nutanix cluster- After the migration, the
administrator observes the following conditions:
• Cluster memory utilization: 64%
• Cluster CPU utilization: 19%
• Cluster storage utilization. 32%
• Average VM CPU utilization: 25%
• Average VM CPU ready%: 24%
• Average VM memory utilization: 60%
Which two changes should the administrator make to improve VM performance? (Choose two.)

A. Reduce the number of vCPUs assigned to VMs.

B. Add more memory to the VMs.
C. Reduce the number of VMs on the hosts.
D. Replace high core count CPUs with high clock rate CPUs.

Answer: A, C
Explanation:
According to the CPU (%) - VMware Docs web search result2, one of the possible causes of high
CPU ready % is over-provisioning vCPUs for a VM or having too many VMs on a host. CPU ready
% indicates the percentage of time that the VM was ready, but could not get scheduled to run
on the physical CPU. High CPU ready % can lead to VM performance problems, such as slow
response time or application latency. To improve VM performance, the administrator should
reduce the number of vCPUs assigned to VMs or reduce the number of VMs on the hosts, so
that there is less contention for CPU resources.

Question: 112
An administrator needs to deploy an application with a large amount of data connected via
Nutanix volumes.
Which two actions should the administrator take when designing the Volume Group? (Choose
two.)

A. Distribute workload across multiple virtual disks

B. Enable RSS (Receive Side Scaling)
C. Use multiple subnets for iSCSI traffic
D. Enable thick provisioning on the Volume Group(s)

Answer: A, B
Explanation:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
According to the Nutanix Volumes - Recommendations And Best Practices web search result3,
two actions that the administrator should take when designing the Volume Group are:
Distribute workload across multiple virtual disks: Use multiple disks rather than a single large
disk for an application. Consider using a minimum of one disk per Nutanix node to distribute the
workload across all nodes in a cluster. Multiple disks per Nutanix node may also improve an
application’s performance. For performance-intensive environments, we recommend using
between four and eight disks per CVM for a given workload.
Enable RSS (Receive Side Scaling): Receive-side scaling (RSS) allows the system to use multiple
CPUs for network activity. With RSS enabled, multiple CPU cores process network traffic,
preventing a single CPU core from becoming a bottleneck. Enabling RSS within hosts can be
beneficial for heavy iSCSI workloads. For VMs running in ESXi environments, RSS requires
VMXNET3 VNICs. For Hyper-V environments, enable VMQ to take full advantage of Virtual RSS.

Question: 113
Microsegmentation was recently enabled in a Nutanix environment. The administrator wants to
leverage Prism Central to create a policy that will block all traffic regardless of direction,
between two groups of VMs identified by their category.
Which policy should be used to meet this requirement?

A. An Application Security Policy

B. A Quarantine Policy
C. A Whitelist-Based Policy
D. An Isolation Environment Policy

Answer: D
Explanation:
According to the web search results, the policy that should be used to meet this requirement is
an Isolation Environment Policy. An Isolation Environment Policy is a type of security policy that
can be created in Prism Central using Flow Network Security, which is a feature that provides
microsegmentation and network security for Nutanix environments1. An Isolation Environment
Policy allows the administrator to isolate a group of VMs from another group of VMs based on
their categories, and block all traffic between them regardless of direction2. This policy can be
useful for creating isolated environments for testing, development, or compliance purposes2.

Question: 114
A system administrator needs to add more VMs to their Nutanix cluster.
Which two actions should the administrator perform to determine if the current cluster can
accommodate the new VMs? (Choose two)

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A. Enable Deduplication and Ensure Coding
B. Utilize Optimize Resources for VM efficiency
C. Determine utilization with Cluster Runway
D. Perform an inventory with Life Cycle Management

Answer: B, C
Explanation:
According to the web search results, the two actions that the administrator should perform to
determine if the current cluster can accommodate the new VMs are:
Utilize Optimize Resources for VM efficiency: Optimize Resources is a feature in Prism Central
that helps the administrator improve the efficiency and performance of their VMs by identifying
and resolving issues such as overprovisioning, inactivity, constraints, or bullying3. By using
Optimize Resources, the administrator can reclaim unused resources and optimize the resource
allocation for their VMs3.
Determine utilization with Cluster Runway: Cluster Runway is a feature in Prism Central that
helps the administrator estimate how long their cluster can continue to run normally based on
the current consumption rate of CPU, memory, and storage resources4. By using Cluster
Runway, the administrator can see how adding more VMs will affect the resource utilization and
capacity of their cluster4.

Question: 115
An administrator responsible for a VDl environment needs to investigate reports of slow logins.
The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login
times. Production workloads are consuming 75% of the host CPU on the cluster. The
administrator increases the vCPU count on all of the VDl VMs.
What are two impacts on the cluster? (Choose two)

A. Increasing CPU counts will decrease memory utilization

B. Increase memory utilization%
C. Increase CPU utilization%
D. Increase CPU ready%

Answer: C, D
Explanation:
According to the web search results, the two impacts on the cluster that will result from
increasing the vCPU count on all of the VDI VMs are:
Increase CPU utilization%: CPU utilization is the percentage of time that a CPU is busy executing
instructions5. By increasing the vCPU count on all of the VDI VMs, the administrator will
increase the demand for CPU resources on the cluster, which will increase the CPU utilization
percentage6.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Increase CPU ready%: CPU ready is the percentage of time that a vCPU is ready to run but is
waiting for a physical CPU to become available5. By increasing the vCPU count on all of the VDI
VMs, the administrator will increase the contention for physical CPU resources on the cluster,
which will increase the CPU ready percentage6. A high CPU ready percentage can indicate
performance issues such as latency or slowdowns5.

Question: 116
An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance
window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)

A. Reconfigure IPMI for the new datacenter

B. Shut down all user VMs in the cluster
C. Relocate the linked LDAP server
D. Stop all Nutanix Files clusters

Answer: B, D
Explanation:
According to the web search results, two steps that should be taken to prepare for relocating an
AHV cluster to a new datacenter during a maintenance window are:
Shut down all user VMs in the cluster: This step is necessary to ensure that there is no data loss
or corruption during the relocation process. The user VMs can be shut down either individually
or in bulk by using the Prism Element web console or the acli command-line interface1.
Stop all Nutanix Files clusters: If the AHV cluster hosts any Nutanix Files clusters, they should be
stopped before relocating the cluster. Nutanix Files clusters are composed of one or more
virtual machines that provide file services to clients. Stopping a Nutanix Files cluster will stop all
the file server VMs and release the resources they consume2. The Nutanix Files clusters can be
stopped by using the Prism Element web console or the ncli command-line interface3.

Question: 117
An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been
deployed and are running, the administrator finds that VMs on the same host are able to
communicate, but are unable to communicate between hosts.
What must be changed to enable full inter-VM communications?

A. Change the spanning-tree port type on the switch.

B. Change the network the VMs are connected to
C. Update the switch to specifically allow VLAN 15
D. The VMs need to have static IP addresses.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: C
Explanation:
According to the web search results, one possible cause of inter-VM communication failure
between hosts is that the switch is not configured to allow VLAN 15 traffic. VLAN 15 is the
default VLAN ID used by AHV for internal communication between CVMs and hosts. If the switch
blocks or drops VLAN 15 packets, it will prevent inter-VM communication across hosts4. To
enable full inter-VM communication, the administrator should update the switch to specifically
allow VLAN 15 traffic on the ports connected to the AHV hosts.

Question: 118
An administrator has a Custom backup application that requires a 2TB disk and runs m
Windows. Throughput is considerably lower than expected.
The application was installed on a VM with the following configuration:
• FOU vCPUs with one core/vCPU
• 4GB of Memory
• One 50GB vDisk for the Windows installation
• One 2TB vDisk for the application
What is the recommended configuration change to improve throughput?

A. Add 4GB of memory to the VM

B. Increase the vCPUs assigned to the VM
C. Span the 2TB disk across four vDisks
D. Increase the number of cores per vCPU

Answer: C
Explanation:
According to the web search results, one recommended configuration change to improve
throughput for a custom backup application that requires a 2TB disk and runs on Windows is to
span the 2TB disk across four vDisks. Spanning is a technique that allows you to create a single
logical disk from multiple physical disks. Spanning can improve throughput by distributing I/O
requests across multiple disks and reducing contention5. To span a disk across four vDisks, the
administrator should create four vDisks of equal size (500 GB each) and attach them to the
VM. Then, in Windows Disk Management, create a spanned volume from the four vDisks and
format it as NTFS6.

An administrator is implementing a VDI solution. The workload will be a series of persistent
desktops in a dedicated storage container within a four-node cluster Storage optimizations
should be set on the dedicated storage container to give optimal performance including during a
node failure event
Which storage optimizations should the administrator set to meet the requirements?

A. Compression only
B. Deduplication and Erasure Coding
C. Compressoion and Deduplication
D. Compression Deduplication and Erasure Coding

Answer: D
Explanation:
According to the web search results, three storage optimizations that should be set on a
dedicated storage container for a VDI solution with persistent desktops are compression,
deduplication and erasure coding. Compression is a technique that reduces the size of data by
removing redundant information. Deduplication is a technique that eliminates duplicate copies
of data blocks and stores only unique blocks. Erasure coding is a technique that increases usable
capacity by reducing the replication factor of data blocks and using parity information
instead7. These three optimizations can improve performance and save storage space for VDI
workloads, especially during a node failure event when data needs to be rebuilt from parity
information8. The administrator can enable these optimizations by using Prism Element web
console or ncli command-line interface9.

Question: 120
HOTSPOT
An administrator has created several custom alert policies, which are applied to the same
entities. Prism Central displays a message that a similar policy exists.

Explanation:

Question: 121
After the initial configuration and upgrade of NCC, the administrator notices these critical alerts:
. IPMI 10.7.133.33 is using default password
. Host 10.7.133.25 is using default password

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
. CVM 10.7.133.31 is using default password
Which two initial cluster configuration tasks were missed during the deployment process?
(Choose two.)

A. CVM password changes

B. BIOS password changes
C. Host password changes
D. Password policy changes

Answer: A, C
Explanation:
The critical alerts listed are indicating that the default passwords are still in use for IPMI, the
host, and the Controller Virtual Machine (CVM). This suggests that the passwords for these
components were not changed from the default during the initial cluster configuration and
deployment process, which is a critical security practice.
A) CVM password changes: The alert for the CVM using the default password indicates that the
CVM password has not been changed. It is a standard security measure to change default
passwords to prevent unauthorized access.
C) Host password changes: Similarly, the alert for the host using the default password indicates
that the default password for the host has not been updated. This applies to the passwords used
to access the hypervisor host directly.
Changing default passwords is a critical step in securing the Nutanix environment. This is
highlighted in Nutanix's best practices and security guidelines, which recommend changing
default passwords as part of the initial configuration to ensure that the environment is not left
vulnerable to unauthorized access due to known default credentials. This process is typically
part of the initial setup procedures outlined in the Nutanix documentation for cluster
deployment and security configuration.
The IPMI alert also points to the need for changing default passwords, but since IPMI (Intelligent
Platform Management Interface) is not specifically mentioned in the provided options, it falls
under the broader category of host-level password changes, which would be covered by option
C.
BIOS password changes (Option B) and Password policy changes (Option D) are also important
but were not directly flagged by the alerts mentioned. BIOS password changes are usually a
separate task and not indicated by the alerts given, while password policy changes are related to
the policies governing password complexity and rotation rather than the initial password setup.

Question: 122
Refer to the Exhibit:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
An administrator is adding a new node to a cluster. The node has been imaged to the same
versions of AHV and AOS that the cluster is
running, configured with appropriate IP addresses, and br0-up has been configured in the same
manner as the existing uplink bonds.
When attempting to add the node to the cluster with the Expand Cluster function in Prism, the
cluster is unable to find the new node.
Based on the above output from the new node, what is most likely the cause of this issue?

A. There is a firewall blocking the discovery traffic from the cluster.

B. The ports on the upstream switch are not configured for LACP.
C. The existing cluster and the expansion node are on different VLANs.
D. LACP configuration must be completed after cluster expansion.

Answer: B
Explanation:
The output in the exhibit indicates that the node's network interfaces (eth0-eth3) are bonded
together using LACP (Link Aggregation Control Protocol) with 'balance-tcp' as the bonding mode
and LACP speed set to 'fast'. For LACP to function correctly, the switch ports to which the node
is connected must also be configured to support LACP. If the ports on the upstream switch are
not configured for LACP, the bond will not be able to establish properly, and the node will not
communicate effectively on the network, making it undiscoverable when attempting to expand
the cluster.
The absence of an operational LACP configuration could prevent the new node from joining the
existing cluster as the node's network interfaces would not be able to pass traffic correctly. This
can be verified by checking the switch configuration to ensure that the ports are set to
participate in an LACP bond.
The other options, such as a firewall blocking discovery traffic (Option A) or the node being on
different VLANs (Option C), are possible causes for a node not being discovered, but given the
specific command output provided, the most likely cause is related to the switch port
configuration for LACP. Option D, regarding completing LACP configuration after cluster
expansion, is not correct because LACP needs to be operational for the node to communicate
with the cluster during the expansion process.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Proper LACP configuration is critical for network communication in a Nutanix AHV cluster, and
this is covered in detail in the Nutanix AHV and Networking documentation. It outlines the steps
for configuring network bonds and LACP on both the AHV hosts and the connecting network
infrastructure.

Question: 123
Refer to Exhibit:

Which statement is true?

A. A critical alert will be triggered if I/O working set size goes over 6000 MB.
B. A critical alert will be triggered when there is an anomaly above 4000 MB.
C. A warning alert will be triggered after 3 anomalies have been catch.
D. A warning alert will be triggered if I/O working set size goes over the blue band.

Answer: B
Explanation:
A) This statement is incorrect because there is no static threshold set to trigger a critical alert at
6000 MB. The graph shows a peak that goes above 6000 MB, but the alert configuration below
does not specify a static threshold at this value.
B) This is the correct statement. The configuration under "Behavioral Anomaly" is set to alert
every time there is an anomaly, with a critical level alert set to trigger when the I/O working set
size is between 0 MB and 4000 MB. The graph illustrates that the anomalies (highlighted in pink)
occur when the working set size exceeds the normal range (blue band). Therefore, any anomaly
detected above 4000 MB would trigger a critical alert.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
C) This statement is incorrect because there is no indication that a warning alert is configured to
trigger after 3 anomalies. The exhibit does not show any configuration that specifies an alert
based on the number of anomalies.
D) This statement is incorrect as there's no indication that a warning alert will be triggered
based on the I/O working set size exceeding the blue band. The alert settings are configured to
ignore anomalies below 4000 MB and to trigger a critical alert for anomalies above this
threshold.
The settings displayed in the exhibit are typically part of Nutanix's Prism infrastructure
management platform, which can set various thresholds for performance metrics and trigger
alerts based on those thresholds. The behavior is defined in the Prism documentation where the
alert configuration is outlined.

Question: 124
An administrator is setting up a Nutanix cluster and needs to configure the default VLAN.

"An administrator has been tasked with increasing security on Nutanix cluster by disabling
password authentication when accessing the CVM and AHV hosts and instead moving to key-
based SSH, What is the easiest way for the administrator to meet these needs? Enable Cluster
Lockdown and provide an RSA key."
Cluster Lockdown mode disables password authentication when accessing the CVM and AHV
hosts and instead requires key-based SSH. To enable Cluster Lockdown mode, you need to
provide an RSA key.
Therefore, by enabling Cluster Lockdown mode and providing an RSA key, you can increase
security on Nutanix cluster by disabling password authentication when accessing the CVM and
AHV hosts and instead moving to key-based SSH with minimal effort.

Prism Element is a graphical user interface that allows you to manage Nutanix clusters1. You can
use Prism Element charts to understand Nutanix cluster workloads and troubleshoot
performance related issues2.
memory optimized virtual machine sizes offer the best performance for SQL Server workloads
on Azure VMs. Adding more RAM to the user VM can help reduce paging and improve query
execution times.
SQL Server performance can be affected by disk latency and throughput. By creating separate
virtual disks for data and logs, you can spread activity across multiple spindles and reduce disk
contention.

Question: 127
Refer to exhibit:

Why has an anomaly been triggered?

A. Controller reached 2500 IOPS.

B. Observed IOPS exceed normal values.
C. Normal Controller behavior has increased.
D. Observed values do not match predicted values.

Answer: B
Explanation:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Question: 128
Refer to Exhibit:

Why has an anomaly been triggered?

A. Because the CPU usage crossed the blue band.

B. Because the blue band range increased over the last 2 days
C. Because the CPU usage dropped belon' 20%
D. Because the CPU usage reached 100%

Answer: A
Explanation:
Nutanix leverages a method for determining the bands called ‘Generalized Extreme Studentized
Deviate Test’. A simple way to think about this is similar to a confidence interval where the
values are between the lower and upper limits established by the algorithm.
Another web source3 shows an example of how anomaly detection works in Nutanix Prism
Central. In the video, you can see that when the observed value of a metric deviates significantly
from the predicted value based on historical data, an anomaly event is triggered and displayed
on a chart.
Therefore, by comparing the observed values with the predicted values based on historical data,
Nutanix anomaly detection can identify abnormal behavior and alert you accordingly.

An administrator needs to enable inline deduplication for a pre-existing storage container.
When trying to enable deduplication on the storage container. this feature is grayed-out.
What is the reason for this behavior?

A. Replication Factor 1 is configured on the storage container.

B. The cluster has less than 5 nodes which is the minimum node-count to enable deduplication.
C. Capacity reservation is not enabled on the storage container.
D. The cluster has hybrid storage and deduplication is supported only on all-flash clusters.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: D
Explanation:
Nutanix supports two types of deduplication: post-process and inline. Post-process
deduplication runs periodically on a schedule and can be enabled on any cluster. Inline
deduplication runs in real time before data is written to disk and can be enabled only on all-flash
clusters.
Therefore, by checking the type of storage and the type of deduplication, you can determine if
you can enable inline deduplication on a storage container or not.
Nutanix inline deduplication is a feature that reduces the stored size and avoids duplicate data
on a storage container1. It is recommended only on some specific scenarios, such as when using
Nutanix Files or virtual desktop infrastructure (VDI) workloads12.

Question: 130
Refer to Exhibit:

An administrator is trying to create a custom alert policy for all VMs.

Why is the Alert warning if field greyed cut?

A. The Alert critical if threshold is set.

B. The Behavioral Anomaly threshold is set.
C. The Enable Policy option checked.
D. The Auto resolve alerts option is checked.

Answer: B

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Explanation:
when you create a custom alert policy, you can choose between two types of thresholds: Static
Threshold and Behavioral Anomaly. Static Threshold allows you to set a fixed value for the
metric that triggers the alert. Behavioral Anomaly allows you to use machine learning to detect
abnormal behavior based on historical data.
If you select Behavioral Anomaly as the threshold type, you cannot set a warning level for the
alert. You can only set a critical level that indicates how much deviation from normal behavior is
considered an anomaly3. Therefore, the Alert warning if field is greyed out when you select
Behavioral Anomaly.

Question: 131
Refer to Exhibit:

An administrator is attempting to create an additional virtual switch on a newly deployed AHV

cluster, using the two currently disconnected interfaces. The administrator is unable to select
the disconnected interfaces when creating the virtual switch.
What is the likely cause of this issue?

A. Only one interface is available on the selected hosts.

B. Interfaces must be connected to the network before they can be assigned.
C. The disconnected interfaces are currently assigned to virtual switch 0,
D. Interfaces must be assigned to virtual switches via the cli

Answer: B
Explanation:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
In Nutanix AHV, when creating a virtual switch and trying to add network interfaces (NICs) to it,
the NICs must be connected to the network before they can be selected and assigned to the
switch. If the interfaces are showing as disconnected, the system will not allow them to be
added to a virtual switch because it cannot verify their operational status or the presence of a
live network connection.
It is a standard requirement for the interfaces to have physical connectivity (i.e., network cables
plugged in and connected to a live switch port) so that the AHV host can detect the link status as
up. Once the interfaces are connected and recognized by the host, they can then be added to a
virtual switch in the Nutanix AHV.
It's important to note that while the command-line interface (CLI) is indeed a powerful tool for
managing network configurations on AHV hosts, and some configurations do indeed require CLI,
the inability to select disconnected interfaces is not specifically a limitation that requires the use
of CLI to overcome. The focus should be on ensuring that the physical connectivity is established
for the interfaces in question.
This behavior is consistent with networking best practices and Nutanix's network configuration
guidelines, as detailed in the Nutanix AHV Networking Guide. This guide explains the
requirements and procedures for configuring virtual switches and managing NICs in a Nutanix
AHV environment.

Question: 132
After configuring Active Directory as the desired authentication service, an administrator is not
able to login into Prism Central using privileged account.
Which configuration must be checked first?

A. Account lock status

B. Role Mapping
C. Local user account
D. Cluster Lockdown

Answer: B
Explanation:
According to the Nutanix Community1, users can authenticate using their Active Directory
credentials when Active Directory support is enabled for Prism Central. To enable Active
Directory support, you need to configure Role Mapping12, which defines how Active Directory

An administrator is trying to put a node into maintenance mode but receives the message
shown in the exhibit.
What is a potential reason for this dialog?

A. LinuxVM1 uses a vDisks stored in a RF1 Datastore

B. LinuxVM1 uses a Volume Group
C. LinuxVM1 uses a virtual GPU.
D. LinuxVM1 uses e vDisks stored in a RF3 Datastore

Answer: A
Explanation:
According to the Nutanix Community1, host maintenance mode is used to safely migrate all the
user virtual machines (VMs) in the host and make sure no VMs are running on the node. If a VM
can’t be migrated to another host, you need to shut down the VM for the host to enter into
maintenance mode.
According to The Virtualist2, a storage container is a logical segmentation of a storage pool that
can be mounted as an NFS datastore on ESXi hosts. You can choose a replication factor (RF) for
each storage container, which determines how many copies of data are stored across different
nodes.

D. Chronos

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: A
Explanation:
Prism is the central service control used by Nutanix to manage the clusters. It provides a unified
view of the entire system, and it is used to control the HTML5 UI, the nCLI, and the REST API.
Prism is used to manage the resources of the system, such as the nodes, storage, and networks,
as well as to monitor the performance of the system and the applications running on it.
https://www.nutanixbible.com/2f-book-of-basics-cluster-components.html
Prism
Key Role: UI and API
· Prism is the management gateway for components and administrators to configure and
monitor the Nutanix cluster. This includes Ncli, the HTML5 UI, and REST API.
· Prism runs on every node in the cluster and uses an elected leader like all components in the
cluster. All requests are forwarded to the leader using Linux Iptables. This allows access to
PRISM using any CVM Ip address.
· Prism communicates with Zeus for cluster configuration data and Cassandra for statistics to
present to the user. It also communicates with the ESXi hosts for VM status and related
information
These are only some of the essential services that make up the CVM functionality. For more
information on all the services and various Nutanix Cluster components, refer to the portal
documentation.

How should the administrator configure the VM to assure optimal performance?

A. With an affinity policy

B. With memory overcommit
C. With 2 vNUMA nodes
D. With Flash Mode enabled

Answer: C
Explanation:
The best way to configure the VM for optimal performance is to set it up with 2 vNUMA nodes.
This will ensure that the VM is configured to take advantage of the CPU and memory resources
available in each node, and it will also ensure that all of the cores are utilized for the best
performance. Additionally, the administrator should ensure that the VM has an affinity policy
set up so that the vCPUs are evenly distributed across the four nodes. Finally, Flash Mode should
be enabled in order to take advantage of the high-performance SSDs that are available in the
cluster

Question: 146

An administrator is troubleshooting vDisk performance issues in a Nutanix cluster with hybrid
disks. The VMs all have Flash Mode enabled.
But users are reporting disk latency.
What could cause the performance issues?

A. Flash mode is disabled when a node fails.

B. Compression is disabled on the vDisk storage container.
C. The VMs vDisks are in multiple containers.
D. Data size for flash mode exceeds 25% of the SSD capacity.

Answer: D
Explanation:
data size for flash mode exceeds 25% of the SSD capacity could cause the performance
issues. Flash mode is a feature that allows vDisks to be pinned to SSDs for faster access, but it
has a limit of 25% of the SSD capacity per node. If this limit is exceeded, some vDisks may be
evicted from flash mode and cause disk latency2.

An administrator is adding a new node to a cluster. The node has been imaged to the same
versions of AHV and AOS that the cluster running, configured with appropriate IP addresses, and
br0-up has been configured the same the existing uplink bonds
When attempting to add the node to the cluster with the Expand Cluster function in Prism , the
cluster is unable to find the new node.
Based on the above output from the new node, what is most likely the cause of this issue?

A. The ports on the upstream switch are not configured for LACP.
B. The existing and the expansion node are on different VLANs.
C. There is a firewall blocking the discovery traffic from the tlu
D. LACP configuration must be completed after cluster expansion

Answer: B
Explanation:
The correct answer is B. The existing and the expansion node are on different VLANs.
The output shows that the new node has a br0-up bond with four interfaces: eth0, eth1, eth2,
and eth3. The bond is configured with LACP active and LACP fallback set to false. This means
that the bond will only work if the upstream switch supports LACP and is configured to form an
LACP group with the four interfaces. However, the output also shows that the bond has no IP
address assigned to it, which indicates that the bond is not operational. One possible reason for
this is that the existing and the expansion node are on different VLANs, and the upstream switch
is not configured to allow the VLAN traffic on the LACP group. This would prevent the new node
from communicating with the cluster and being discovered by the Expand Cluster function in
Prism.
To verify this, the administrator can check the VLAN configuration on the upstream switch and
compare it with the existing nodes. Alternatively, the administrator can use the “manage_ovs
show_uplinks” command on an existing node and compare the output with the new node. If
there is a VLAN mismatch, the administrator can either change the VLAN configuration on the
switch or on the new node to match the existing nodes.

 Question: 156
Refer to the exhibit.

An administrator is trying to implement the solution that is shown in the exhibit, but has been
unsuccessful.
Based on the diagram, what is causing the issue?

A. A remote Witness VM
B. Active containers in both sites
C. Network latency
D. Unsupported hypervisor

Answer: C
Explanation:
The correct answer is C. Network latency.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
The diagram shows a solution that uses synchronous replication between two remote
protection domains, cluster site A and cluster site B. Synchronous replication is a feature that
allows near-zero RPO (recovery point objective) by replicating data to the remote site before
acknowledging writes to the local site. However, synchronous replication has some
requirements and limitations that must be met for it to work properly. One of these
requirements is that the network latency between the two sites must be less than or equal to 5
ms1. If the network latency is higher than 5 ms, the synchronous replication will fail and the
protection policy will be suspended2.
Therefore, based on the diagram, the most likely cause of the issue is that the network latency
between cluster site A and cluster site B is higher than 5 ms, which prevents the synchronous
replication from working. To verify this, the administrator can use the “ncli cluster ping”
command to measure the network latency between the two sites3. If the network latency is
indeed higher than 5 ms, the administrator can either improve the network performance or
switch to a different replication mode, such as near-synchronous or asynchronous.

D. Create Affinity Project

Answer: A
Explanation:
A VM-VM anti-Affinity policy is a rule that ensures that two or more VMs don’t run on the same
AHV host. It’s useful when an application provides HA and an AHV host can’t be an application’s
single point of failure1. In this case, the SQL cluster VMs should have a VM-VM anti-Affinity
policy configured to prevent them from running on the same host and causing an outage if that
host fails. A VM-VM anti-Affinity policy can be created using the aCLI commands2. The other
options are not relevant for this scenario.

Question: 159
An administrator needs to increase bandwidth available to the AHV host and to the CVM.
How should the administrator complete this task?

A. In Prism, update vs0 to change the configuration to Active-Active.

B. Use manage-ovs commands to update br0 change the configuration to Active-Active.
C. In Prism, create a vsl interface and add any remaining uplinks.
D. Use manage-ovs commands to create br1 and add any remaining uplinks

Answer: B
Explanation:
The default network configuration for AHV hosts and CVMs is a bond named br0-up with two or
more uplinks in active-backup mode. This means that only one uplink is active at a time, while
the others are in standby mode. This provides high availability, but not load balancing or
increased bandwidth. To increase the bandwidth available to the AHV host and the CVM, the
administrator can change the bond mode to Active-Active, which allows all uplinks to be used
simultaneously. This can be done using the manage-ovs commands on each AHV host. The steps
are as follows1:
Log in to the AHV host using SSH.
Enter maintenance mode on the CVM by running allssh 'cluster status | grep -i cvm | grep -i
down'.
Change the bond mode to Active-Active by running manage_ovs --bond_mode active-active
update_uplinks br0-up <uplink_list>, where <uplink_list> is a comma-separated list of uplink
interfaces (for example, eth0,eth1).
Verify the bond mode by running manage_ovs show_uplinks.
Exit maintenance mode on the CVM by running allssh 'cluster start'.

 Question: 160
Which inefficient VM Profile can be used to identify a VM that consumes too many resources
and causes other VMs to starve?

A. Over-provisioned VM
B. Inactive VM
C. Bully VM
D. Constrained VM

Answer: C
Explanation:
A bully VM is a VM that consumes too many resources and causes other VMs to starve. A bully
VM can affect the performance and availability of other VMs on the same host or cluster by
hogging CPU, memory, disk, or network resources. A bully VM can be identified by using the VM
Profile feature in Prism Central2. The VM Profile feature analyzes the resource utilization of
each VM and assigns it a profile based on its efficiency and impact on other VMs. The profiles
are as follows3:
Efficient: The VM is well-provisioned and has optimal resource utilization.
Over-provisioned: The VM has more resources than it needs and has low resource utilization.
Constrained: The VM has less resources than it needs and has high resource utilization.
Inactive: The VM has no resource utilization and is idle or powered off.
Bully: The VM has high resource utilization and causes contention for other VMs.
To identify a bully VM, the administrator can use Prism Central to view the VM Profile
dashboard and filter by profile type. The dashboard shows the number of VMs in each profile
type, as well as their resource consumption and efficiency score. The administrator can also drill
down into each VM to see its detailed metrics and recommendations for optimization.

Question: 161
What is he recommended approach for a constrained VM?

A. Reboot the VM
B. Delete the VM.
C. Increase the VM resources.
D. Decrease the VM resources

Answer: C
Explanation:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
A constrained VM is one that does not have enough resources for the demand and can lead to
performance bottlenecks. A VM is considered constrained when it exhibits one or more of the
following baseline values, based on the past 21 days: CPU usage > 90% (moderate), 95% (severe)
CPU ready time > 5%, 10% Memory usage > 90%, 95% Memory swap rate > 0 Kbps1. To provide
adequate host resources, resize (increase) the constrained VMs1.

Question: 162
An administrator wants to expand the Failure Domain level of a cluster.
What two options are available? (Choose two.)

A. Node
B. Data Center
C. Block
D. Rack

Answer: C, D
Explanation:
Nutanix clusters are resilient to a drive, node, block, and rack failures because they use
redundancy factor 2 by default, allowing Nutanix clusters to self-heal2. Failure scenarios can be
thought of in terms of fault domains, which are the physical or logical parts of a computing
environment or location that are adversely affected when a device or service experiences an
issue or outage3. There are four fault domains in a Nutanix cluster: Disk, Node, Block, and
Rack4. Block and Rack are two options that are available for expanding the failure domain level
of a cluster. Block fault tolerance is enabled by default and ensures that data is replicated across
different blocks in a cluster5. Rack fault tolerance has to be configured manually and ensures
that data is replicated across different racks in a cluster4.

Question: 163
What is a requirement to enable Flow Networking?

A. A dedicated virtual switch has been created for Flow Networking.

B. Flow Micro segmentation must be enabled.
C. Microservices infrastructure must be enabled.
D. Prims Central is using a three-node scale-out deployment

Answer: C
Explanation:

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Flow Networking is a feature that enables software-defined networking for AHV clusters. It
allows users to create and manage virtual private clouds (VPCs), subnets, and network services
such as NAT, DHCP, routing, and VPN. Flow Networking also supports service insertion and
chaining, which enables integration with third-party network functions such as firewalls and
load balancers. Flow Networking is built on top of the microservices infrastructure (MSP) in
Prism Central, which provides the platform for running various Nutanix services such as Calm,
Karbon, and Objects. Therefore, to enable Flow Networking, the MSP must be enabled first on
Prism Central1. The MSP can be enabled from the Prism Central settings page or from the
command line interface (CLI) of the Prism Central VM2. Enabling the MSP will also enable Flow
Microsegmentation, which is another feature that provides network security and visibility for
AHV clusters.

Question: 164
A user running a Computer Aided Design (CAD) application is complaining about slow response
time within the VM, particular when moving windows or rendering images.
Which VM metric will guide the administrator toward diagnosing the problem?

A. Storage Controller Latency

B. GPU Usage
C. Swap in Rate
D. Hypervisor Memory Usage (%)

Answer: B
Explanation:
A GPU (graphics processing unit) is a specialized hardware device that can accelerate graphics
rendering and computation for applications that use APIs such as DirectX, OpenGL, CUDA, and
OpenCL. A GPU can also offload the CPU from encoding and decoding tasks for remote display
protocols such as Frame Remote Desktop Protocol (FRP). A VM can use a GPU either by directly
accessing a physical GPU (pGPU) on the host or by using a virtual GPU (vGPU) that shares a
pGPU with other VMs. A user running a computer aided design (CAD) application may benefit
from using a GPU or a vGPU to improve the performance and responsiveness of the application,
especially when moving windows or rendering images. However, if the GPU or vGPU is not
properly configured or provisioned, the user may experience slow response time within the VM.
Therefore, to diagnose the problem, the administrator should monitor the GPU Usage metric for
the VM. The GPU Usage metric shows the percentage of GPU resources that are consumed by
the VM over time3. The administrator can use Prism Central to view the GPU Usage metric for
each VM in a chart or a widget4. The administrator can also use Prism Central to view other
metrics related to GPU performance, such as GPU Memory Usage, GPU Encoder Usage, and GPU
Decoder Usage3. By analyzing these metrics, the administrator can determine if the VM is using
the GPU efficiently and optimally, or if it needs more or less GPU resources.

 Question: 165
An administrator needs to ensure logs, alerts and information is consistent across clusters that
are located in different countries.
Which service needs to be configured?

A. SMTP
B. DNS
C. SNMP
D. NTP

Answer: D
Explanation:
NTP service needs to be configured to ensure logs, alerts and information is consistent across
clusters that are located in different countries. NTP stands for Network Time Protocol and it is
used to synchronize the clocks of all the nodes in a cluster1. This helps to maintain accurate
timestamps for logs, alerts and other information that are generated by Nutanix clusters1.

Question: 166
An administrator manages an AHV cluster that is dedicated to a dev/test environment. The
administrator receiving complaints from users that they are unable to create new VMs on the
cluster.
After the reviewing the cluster, the administrator finds that the memory resources are almost
fully utilized, with many VMs over-provisioned on memory.
What option is the most efficient resolution to enable additional VMs to be created?

A. Enable Memory Overcommit on the over-provisioned VMs.

B. Enable Memory HA on the over-provisioned VMs.
C. Upgrade the nodes with additional memory DlMMs.
D. Disable HA Reservation on the cluster.

Answer: A
Explanation:
Enable Memory Overcommit on the over-provisioned VMs is the most efficient resolution to
enable additional VMs to be created. Memory overcommit allows VMs to use more memory
than physically available on a host by compressing and swapping memory pages to
storage1. This can improve memory utilization and increase VM density on a cluster1. However,
memory overcommit is not supported when HA is configured to use reserved hosts, so you may
need to disable HA reservation on the cluster before enabling memory overcommit1.

Question: 168
During an AHV upgrade, an administrator finds that a critical VM was powered off rather than
migration to another host.
Which scenario explains this behavior?

A. NO AHV hosts were able to be scheduled.

B. The VM OS hung during migration.
C. The VM was on the same host as the acropolis leader.
D. The VM was marked as an agent VM.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
 Answer: D
Explanation:
An agent VM is a special type of VM that is used for running services or applications that are not
affected by high availability (HA) events or host maintenance. An agent VM is never migrated to
any other host in the cluster. If an HA event occurs or the host is put in maintenance mode,
agent VMs are powered off and are powered on on the same host once that host returns to a
normal state. This behavior is different from regular VMs, which are migrated to another host in
the cluster if possible, or restarted on the same host if not possible1.
Therefore, during an AHV upgrade, an administrator may find that a critical VM was powered off
rather than migrated to another host if the VM was marked as an agent VM. This can be done
either from the Prism web console by selecting the Use this VM as an agent VM option in the
Update VM dialog box, or from the aCLI by using the vm.create or vm.update commands with
the agent_vm=true parameter2. To avoid this situation, the administrator should ensure that
any critical VMs are not marked as agent VMs before starting the AHV upgrade.

Question: 169
Which two types of granular RBAC does Nutanix provide for AHV hosts? (Choose two.)

A. Category based
B. Project based
C. Disk based
D. Cluster based

Answer: A, D
Explanation:
Nutanix provides two types of granular RBAC for AHV hosts: category based and cluster based3.
Category based RBAC allows administrators to assign roles to users or groups based on
categories, which are key-value pairs that can be applied to various entities in Prism Central,
such as clusters, hosts, VMs, images, and networks. Categories can be used to group entities by
different criteria, such as department, project, environment, or location. For example, an
administrator can create a category key named Department and assign different values to it,
such as Finance, Marketing, or Engineering. Then, the administrator can apply this category to
different clusters or hosts and assign roles to users or groups based on this category. This way,
users or groups can have different levels of access to different clusters or hosts depending on
their department4.
Cluster based RBAC allows administrators to assign roles to users or groups based on specific
clusters registered in Prism Central. For example, an administrator can create a role named
Cluster Admin and assign it to a user or group for a particular cluster. This way, the user or
group can have full access to that cluster and its hosts and VMs, but not to other clusters5.

 Question: 170
An administrator is tasked with configuring networking on an AHV cluster and needs to optimize
for maximum single VM throughput.
Which bond mode should the administrator select?

A. Active-Active with Mac pinning

B. Active-Active
C. Active-Backup
D. No Uplink Bond

Answer: B
Explanation:
Active-Active is a bond mode that allows all uplinks in the bond to be used simultaneously for
traffic transmission and reception. This bond mode provides load balancing and increased
bandwidth for the AHV host and its VMs. Active-Active bond mode uses a hashing algorithm
based on source MAC addresses to distribute traffic across different uplinks in the bond. Each
individual VM NIC uses only a single bond member interface at a time, but multiple VM NICs are
spread across different bond member interfaces. As a result, it is possible for a Nutanix AHV
node with two 10 Gb interfaces to use up to 20 Gbps of network throughput, while individual
VMs have a maximum throughput of 10 Gbps6.
Therefore, if an administrator needs to optimize for maximum single VM throughput, they
should select Active-Active bond mode for their AHV cluster. This bond mode can be configured
using Prism Element UI or manage-ovs commands on each AHV host7. No additional
configuration is required on the upstream switch side, as long as the switches are
interconnected physically or virtually and both uplinks trunk the same VLANs8.

Question: 171
Refer to Exhibit:

An administrator wants to replace and old node with a node of newer generation in a 3-node
cluster. The administrator has already chosen the appropriate node. But unable to remove it
from the cluster.
Why is the Remove Host option not shown in the exhibit?

A. The host needs to be placed into maintenance Mode before.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
B. It is only possible to remove a host from a cluster using CLI.
C. It is not possible to remove a node from a the cluster using Prism Central
D. It is not possible to remove a host from a 3-node cluster.

Answer: D
Explanation:
A Nutanix cluster requires a minimum of three nodes to maintain quorum and data availability.
Removing a node from a 3-node cluster would violate the redundancy factor and cause data
loss. Therefore, it is not possible to remove a host from a 3-node cluster using Prism or CLI. The
only way to replace a node in a 3-node cluster is to use the Foundation tool, which will erase the
existing cluster configuration and create a new cluster with the new node1.

Question: 172
An administrator needs to create a new Linux image and will to do the following as part of the
VM deployment:
* Set the OS hostname
* Add custom users
* Add keys
* Run custom scripts
What package needs to be installed in the Linux image to facilitate this automation?

A. CloudInit
B. Sysprep
C. Kickstart
D. NGT

Answer: A
Explanation:
CloudInit is a package that contains utilities for early initialization of cloud instances. It allows
you to customize virtual machines provided by a cloud vendor by modifying the generic OS
configuration on boot. You can use CloudInit to set the OS hostname, add custom users, add
keys, run custom scripts, and more2. CloudInit is supported by most major Linux and FreeBSD
operating systems and works across different cloud platforms3. Sysprep is a tool for Windows
operating systems that prepares an installation for cloning, auditing, and customer delivery4.

Question: 173
An administrator has created a Nutanix managed it a VLAN ID of 512.

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Several VMs have been created, and the administrator notices that the can successfully
communicate with other VMs on that VLAN.
Provided they are on the host, but cannot communicate with VMs that reside on different hosts
in the cluster.
What is most likely thee cause of this issue?

A. There is a firewall rule blockingVLAN512 traffic.

B. VLANS12 is a reserved VLAN ID, and not usable for guest VMs.
C. The VLAN was not created on the upstream switches.
D. The administrator did not create the VLAN on all hosts

Answer: C
Explanation:
The correct answer is C. The VLAN was not created on the upstream switches.
A VLAN (virtual local area network) is a logical segmentation of a physical network that allows
devices on the same VLAN to communicate with each other, regardless of their physical
location. A VLAN also isolates the devices on different VLANs from each other, unless there is a
router or a layer 3 switch that can route traffic between VLANs. To create a VLAN, the
administrator needs to configure the network devices that are involved in the VLAN, such as
switches, routers, and hosts. The administrator also needs to assign a unique VLAN ID to each
VLAN, which is a number between 1 and 4094 that identifies the VLAN1.
In Nutanix AHV, the administrator can create a Nutanix managed network with a specific VLAN
ID for guest VMs. This network can be assigned to VM NICs using Prism Element or Prism
Central. However, creating a Nutanix managed network does not automatically create the VLAN
on the upstream switches that connect the AHV hosts. The administrator needs to manually
configure the upstream switches to allow the VLAN traffic on the ports that connect to the AHV
hosts. The administrator also needs to ensure that the upstream switches are interconnected
physically or virtually and can forward traffic between different VLANs if needed2.
Therefore, if an administrator has created a Nutanix managed network with a VLAN ID of 512
and notices that the VMs on that network can only communicate with other VMs on the same
host, but not with VMs on different hosts in the cluster, the most likely cause of this issue is that
the VLAN was not created on the upstream switches. This means that the switches are dropping
or blocking the traffic with VLAN ID 512 and preventing it from reaching other hosts or VMs. To
resolve this issue, the administrator should create the VLAN on the upstream switches and allow
it on the ports that connect to the AHV hosts3.

Question: 174
An administrator is concerned about the amount of data that a VM reading and writing to the
storage fabric.
Which metric will provide that data?

A. Host Hypervisor IO Bandwidth

B. Host Disk IOPS

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
C. VM Storage Controller IOPS
D. VM Storage Controller Bandwidth

Answer: D
Explanation:
The correct answer is D. VM Storage Controller Bandwidth.
VM Storage Controller Bandwidth is a metric that measures the amount of data that a VM is
reading and writing to the storage fabric. The storage fabric is the network of storage controllers
(CVMs) that provide distributed and fault-tolerant storage services to the VMs on the Nutanix
cluster. The VM Storage Controller Bandwidth metric shows the read and write bandwidth in
megabytes per second (MBps) for each VM. The higher the bandwidth, the more data the VM is
transferring to and from the storage fabric1.
The administrator can use Prism Central to view the VM Storage Controller Bandwidth metric
for each VM in a chart or a widget. The administrator can also use Prism Central to view other
metrics related to the VM’s storage performance, such as VM Storage Controller IOPS, VM
Storage Controller Latency, and VM Disk Usage2.

Question: 175
Refer to the Exhibit:

An administrator receives complaints of poor performance in a particular VM.

Based on the VM performance metric, what is the most likely cause of this behavior?

A. Oplog is full cannot serve IO request from this VM.

B. The host’s CPU is severely overloaded.
C. SSD tier is not big enough to serve workloads’ IOPS demand.
D. The VM needs more vCPUs

Answer: B

Visit us athttps://www.examsboost.com/test/ncp-mci-6-5/
Explanation:
Based on the VM performance metrics shown in the exhibit, the most likely cause of the poor
performance in the particular VM is that the host’s CPU is severely overloaded. This is indicated
by the high percentage of Hypervisor CPU Ready Time, which is shown as 96% in the CPU ready
chart. CPU Ready Time is a metric that shows the amount of time a VM is ready to run but is
unable to run because the host CPU resources are not available. In a healthy environment, this
value is typically low. A high percentage indicates that the VMs are waiting for available CPU
cycles, which means the CPU is not able to schedule the VM effectively, often due to
overcommitment or heavy CPU load.
When the CPU ready time is consistently high, it is a clear indicator that the VM is frequently
waiting for CPU resources, which can lead to performance issues such as sluggishness or delays
in processing. It is not related to the storage subsystem (Oplog fullness or SSD tier size), nor
directly to the number of vCPUs assigned to the VM. While adding more vCPUs might seem like
a solution, it could actually exacerbate the issue if the host is already CPU constrained.
To resolve this issue, an administrator should consider balancing the load across the hosts more
effectively, possibly by using Nutanix's built-in automation and balancing features, or by scaling
out the cluster to add more CPU resources. It is also advisable to check for any VMs with
unusually high CPU demand and to adjust resource allocation as needed. Nutanix provides
extensive documentation and guidelines in their Resource Management Guide to help
administrators identify and resolve such performance issues.
