NEW QUESTION 1
- (Topic 3)
A company plans to migrate to the AWS Cloud. The company is gathering information about its on-premises infrastructure and requires information such as the
hostname, IP address, and MAC address.
Which AWS service will meet these requirements?
A. AWS DataSync
B. AWS Application Migration Service
C. AWS Application Discovery Service
D. AWS Database Migration Service (AWS DMS)
Answer: C
Explanation:
AWS Application Discovery Service is a service that helps you plan your migration to the AWS Cloud by collecting usage and configuration data about your on-
premises servers and databases. This data includes information such as the hostname, IP address, and MAC address of each server, as well as the performance
metrics, network connections, and processes running on them. You can use AWS Application Discovery Service to discover your on-premises inventory, map the
dependencies between servers and applications, and estimate the cost and effort of migrating to AWS. You can also export the data to other AWS services, such
as AWS Migration Hub and AWS Database Migration Service, to support your migration tasks. AWS Application Discovery Service offers two ways of performing
discovery: agentless discovery and agent-based discovery. Agentless discovery uses a virtual appliance that you deploy on your VMware vCenter to collect data
from your virtual machines and hosts. Agent-based discovery uses an agent that you install on each of your physical or virtual servers to collect data. You can
choose the method that best suits your environment and needs. AWS DataSync is a service that helps you transfer data between your on-premises storage and
AWS storage services, such as Amazon S3, Amazon EFS, and Amazon FSx for Windows File Server. AWS DataSync does not collect information about your on-
premises infrastructure, but rather focuses on optimizing the data transfer speed, security, and reliability. AWS Application Migration Service is a service that helps
you migrate your applications from your on-premises or cloud environment to AWS without making any changes to the applications, their architecture, or the
migrated servers. AWS Application Migration Service does not collect information about your on- premises infrastructure, but rather uses a lightweight agent to
replicate your servers as Amazon Machine Images (AMIs) and launch them as EC2 instances on AWS. AWS Database Migration Service is a service that helps
you migrate your databases from your on-premises or cloud environment to AWS, either as a one-time migration or as a continuous replication. AWS Database
Migration Service does not collect information about your on-premises infrastructure, but rather uses a source and a target endpoint to connect to your databases
and transfer the data. References: AWS Application Discovery Service, AWS DataSync, AWS Application Migration Service, [AWS Database Migration Service]

- (Topic 3)
A company wants to make an upfront commitment for continued use of its production Amazon EC2 instances in exchange for a reduced overall cost.
Which pricing options meet these requirements with the LOWEST cost? (Select TWO.)
A. Spot Instances
B. On-Demand Instances
C. Reserved Instances
D. Savings Plans
E. Dedicated Hosts
Answer: CD
Explanation:
Reserved Instances (RIs) are a pricing model that allows you to reserve EC2 instances for a specified period of time (one or three years) and receive a significant
discount compared to On-Demand pricing. RIs are suitable for workloads that have predictable usage patterns and require a long-term commitment. You can
choose between three payment options: All Upfront, Partial Upfront, or No Upfront. The more you pay upfront, the greater the discount1.
Savings Plans are a flexible pricing model that can help you reduce your EC2 costs by up to 72% compared to On-Demand pricing, in exchange for a commitment
to a consistent amount of usage (measured in $/hour) for a one or three year term. Savings Plans apply to usage across EC2, AWS Lambda, and AWS Fargate.
You can choose between two types of Savings Plans: Compute Savings Plans and EC2 Instance Savings Plans. Compute Savings Plans offer the most flexibility
and apply to any instance family, size, OS, tenancy, or region. EC2 Instance Savings Plans offer the highest discount and apply to a specific instance family within
a region2.
Spot Instances are a pricing model that allows you to bid for unused EC2 capacity in the AWS cloud and are available at a discount of up to 90% compared to On-
Demand pricing. Spot Instances are suitable for fault-tolerant or stateless workloads that can run on heterogeneous hardware and have flexible start and end
times. However, Spot Instances are not guaranteed and can be interrupted by AWS at any time if the demand for capacity increases or your bid price is lower than
the current Spot price3.
On-Demand Instances are a pricing model that allows you to pay for compute capacity by the hour or second with no long-term commitments. On-Demand
Instances are suitable for short-term, spiky, or unpredictable workloads that cannot be interrupted, or for applications that are being developed or tested on EC2 for
the first time. However, On-Demand Instances are the most expensive option among the four pricing models4.
Dedicated Hosts are physical EC2 servers fully dedicated for your use. Dedicated Hosts can help you reduce costs by allowing you to use your existing server-
bound software licenses, such as Windows Server, SQL Server, and SUSE Linux Enterprise Server. Dedicated Hosts can be purchased On-Demand or as part of
Savings Plans. Dedicated Hosts are suitable for workloads that need to run on dedicated physical servers or have strict licensing requirements. However,
Dedicated Hosts are not the lowest cost option among the four pricing models.

Which option is a customer responsibility under the AWS shared responsibility model?
Answer: B
Explanation:
The option that is a customer responsibility under the AWS shared responsibility model is B. Application data security.
According to the AWS shared responsibility model, AWS is responsible for the security of the cloud, while the customer is responsible for the security in the cloud.
This means that AWS manages the security of the underlying infrastructure, such as the hardware, software, networking, and facilities that run the AWS services,
while the customer manages the security of their applications, data, and resources that they use on top of AWS12. Application data security is one of the customer
responsibilities under the AWS shared responsibility model. This means that the customer is responsible for protecting their application data from unauthorized
access, modification, deletion, or leakage. The customer can use various AWS services and features to help with application data security, such as encryption, key
management, access control, logging, and auditing12. Maintenance of underlying hardware of Amazon EC2 instances is not a customer responsibility under the
AWS shared responsibility model. This is part of the AWS responsibility to secure the cloud. AWS manages the physical servers that host the Amazon EC2
instances and ensures that they are updated, patched, and replaced as needed13.
Physical security of data centers is not a customer responsibility under the AWS shared responsibility model. This is also part of the AWS responsibility to secure
the cloud. AWS operates and controls the facilities where the AWS services are hosted and ensures that they are protected from unauthorized access,
environmental hazards, fire, and theft14. Maintenance of VPC components is not a customer responsibility under the AWS shared responsibility model. This is a
shared responsibility between AWS and the customer. AWS provides the VPC service and ensures that it is secure and reliable, while the customer configures and
manages their own VPCs and related components, such as subnets, route tables, security groups, network ACLs, gateways, and endpoints15.

A company needs to migrate a PostgreSQL database from on-premises to Amazon RDS. Which AWS service or tool should the company use to meet this
requirement?
Answer: C
Explanation:
AWS Database Migration Service (AWS DMS) is a managed and automated service that helps you migrate your databases from your on-premises or cloud
environment to AWS, either as a one-time migration or as a continuous replication. AWS DMS supports migration between 20-plus database and analytics
engines, such as PostgreSQL, Oracle, MySQL, SQL Server, MongoDB, Amazon Aurora, Amazon RDS, Amazon Redshift, and Amazon S3. AWS DMS also
provides schema conversion and validation tools, as well as monitoring and security features. AWS DMS is a cost-effective and reliable solution for database
migration, as you only pay for the compute resources and additional log storage used during the migration process, and you can minimize the downtime and data
loss with
Multi-AZ and ongoing replication12
To migrate a PostgreSQL database from on-premises to Amazon RDS using AWS DMS, you need to perform the following steps:
? Create an AWS DMS replication instance in the same AWS Region as your target Amazon RDS PostgreSQL DB instance. The replication instance is a server
that runs the AWS DMS replication software and connects to your source and target endpoints. You can choose the instance type, storage, and network settings
based on your migration requirements3
? Create a source endpoint that points to your on-premises PostgreSQL database.
You need to provide the connection details, such as the server name, port, database name, user name, and password. You also need to specify the engine name
as postgres and the SSL mode as required4
? Create a target endpoint that points to your Amazon RDS PostgreSQL DB instance. You need to provide the connection details, such as the server name, port,
database name, user name, and password. You also need to specify the engine name as postgres and the SSL mode as verify-full.
? Create a migration task that defines the migration settings and options, such as the replication instance, the source and target endpoints, the migration type (full
load, full load and change data capture, or change data capture only), the table mappings, the task settings, and the task monitoring role. You can also use the
AWS Schema Conversion Tool (AWS SCT) to convert your source schema to the target schema and apply it to the target endpoint before or after creating the
migration task.
? Start the migration task and monitor its progress and status using the AWS DMS console, the AWS CLI, or the AWS DMS API. You can also use AWS
CloudFormation to automate the creation and execution of the migration task.
The other options are not suitable for migrating a PostgreSQL database from on-premises to Amazon RDS. Cloud Adoption Readiness Tool is a tool that helps you
assess your readiness for cloud adoption based on six dimensions: business, people, process, platform, operations, and security. It does not perform any
database migration tasks. AWS Migration Hub is a service that helps you track and manage the progress of your application migrations across multiple AWS and
partner services, such as AWS DMS, AWS Application Migration Service, AWS Server Migration Service, and CloudEndure Migration. It does not perform any
database migration tasks itself, but rather integrates with other migration services. AWS Application Migration Service is a service that helps you migrate your
applications from your on-premises or cloud environment to AWS without making any changes to the applications, their architecture, or the migrated servers. It
does not support database migration, but rather replicates your servers as Amazon Machine Images (AMIs) and launches them as EC2 instances on AWS.

A company wants to minimize network latency between its Amazon EC2 instances. The EC2 instances do not need to be highly available.
Which solution meets these requirements?
Answer: A
Explanation:
Using EC2 instances in a single Availability Zone is a solution that meets the requirements of minimizing network latency between the EC2 instances and not
needing high availability. An Availability Zone is a physically isolated location within an AWS Region that has its own power, cooling, and network connectivity. EC2
instances within the same Availability Zone can communicate with each other using low-latency private IP addresses. However, EC2 instances in a single
Availability Zone are not highly available, because they are vulnerable to failures or disruptions that affect the Availability Zone

A company needs to run a workload for several batch image rendering applications. It is acceptable for the workload to experience downtime.
Which Amazon EC2 pricing model would be MOST cost-effective in this situation?
A. On-Demand Instances
B. Reserved Instances
C. Dedicated Instances
D. Spot Instances
Answer: D
Explanation:
Amazon EC2 Spot Instances are instances that use spare EC2 capacity that is available at up to a 90% discount compared to On-Demand prices. You can use
Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, high-performance computing (HPC), and test
& development workloads. Spot Instances are ideal for workloads that can be interrupted, such as batch image rendering applications1. On-Demand Instances are
instances that let you pay for compute capacity by the hour or second (minimum of 60 seconds) with no long-term commitments. This frees you from the costs and
complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs2. Reserved
Instances are instances that provide you with a significant discount (up to 75%) compared to On-Demand Instance pricing. In exchange, you select a term and
make an upfront payment to reserve a certain amount of compute capacity for that term3. Dedicated Instances are instances that run in a VPC on hardware that’s
dedicated to a single customer. Your Dedicated Instances are physically isolated at the host hardware level from instances that belong to other AWS accounts4.

- (Topic 3)
Which Amazon EC2 instance pricing model can provide discounts of up to 90%?
A. Reserved Instances
B. On-Demand
C. Dedicated Hosts
D. Spot Instances
Answer: D
Explanation:
Spot Instances are Amazon EC2 instances that are available at a discounted price compared to On-Demand pricing. Spot Instances use spare EC2 capacity that
is not being used by other customers, and the price fluctuates based on supply and demand. Customers can request Spot Instances for their applications and
specify the maximum price they are willing to pay per hour. If the Spot price is lower than the customer’s bid, the Spot Instance is launched and the customer pays
the current Spot price. However, if the Spot price rises above the customer’s bid, the Spot Instance is terminated by AWS and the customer is charged for the
partial hour of usage. Therefore, Spot Instances can provide discounts of up to 90% or more, but they are not suitable for applications that require continuous or
predictable availability. Spot Instances are recommended for applications that are flexible, fault-tolerant, or have low priority, such as batch processing, data
analysis, or testing and development.

A company wants to migrate its high-performance computing (HPC) application to Amazon EC2 instances. The application has multiple components. The
application must have fault tolerance and must have the ability to fail over automatically.
Which AWS infrastructure solution will meet these requirements with the LEAST latency between components?
Answer: C
Explanation:
Using EC2 instances in multiple Availability Zones is an AWS infrastructure solution that meets the requirements of migrating a high performance computing
(HPC) application to AWS with fault tolerance and failover capabilities, and with the least latency between components. An Availability Zone is a physically isolated
location within an AWS Region that has its own power, cooling, and network connectivity. EC2 instances within the same Region can communicate with each other
using low-latency private IP addresses. By using EC2 instances in multiple Availability Zones, the company can achieve fault tolerance and failover for their HPC
application, because they can distribute the workload and data across different locations that are independent of each other. If one Availability Zone becomes
unavailable or impaired, the company can redirect the traffic and data to another Availability Zone without affecting the performance and availability of the
application5

What is the purpose of having an internet gateway within a VPC?
Answer: B
Explanation:
An internet gateway is a service that allows for internet traffic to enter into a VPC. Otherwise, a VPC is completely segmented off and then the only way to get to it
is potentially through a VPN connection rather than through internet connection. An internet gateway is a logical connection between an AWS VPC and the
internet. It supports IPv4 and IPv6 traffic. It does not cause availability risks or bandwidth constraints on your network traffic1. An internet gateway enables
resources in your public subnets (such as EC2 instances) to connect to the internet if the resource has a public IPv4 address or an IPv6 address. Similarly,
resources on the internet can initiate a connection to resources in your subnet using the public IPv4 address or IPv6 address2. An internet gateway also provides a
target in your VPC route tables for internet-routable traffic. For communication using IPv4, the internet gateway also performs network address translation (NAT).
For communication using IPv6, NAT is not needed because IPv6 addresses are public2. To enable access to or from the internet for instances in a subnet in a
VPC using an internet gateway, you must create an internet gateway and attach it to your VPC, add a route to your subnet’s route table that directs internet-bound
traffic to the internet gateway, ensure that instances in your subnet have a public IPv4 address or an IPv6 address, and ensure that your network access control
lists and security group rules allow the desired internet traffic to flow to and from your instance2. References: Connect to the internet using an internet gateway,

for authenticated users, but not for applications4.
Answer: B
Explanation:
Amazon EC2 instance store provides temporary block-level storage for your EC2 instance. This storage is located on disks that are physically attached to the host
computer. Instance store is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content.
It can also be used to store temporary data that you replicate across a fleet of instances, such as a load-balanced pool of web servers. An instance store consists
of one or more instance store volumes exposed as block devices. The size of an instance store as well as the number of devices available varies by instance type
and instance size. The virtual devices for instance store volumes are ephemeral[0-23]. Instance types that support one instance store volume have ephemeral0.
Instance types that support two or more instance store volumes have ephemeral0, ephemeral1, and so on. Instance store pricing Instance store volumes are
included as part of the instance’s usage cost. The data on an instance store volume persists even if the instance is rebooted. However, the data does not persist if
the instance is stopped, hibernated, or terminated. When the instance is stopped, hibernated, or terminated, every block of the instance store volume is
cryptographically erased. Therefore, do not rely on instance store volumes for valuable, long-term data. If you need to retain the data stored on an instance store
volume beyond the lifetime of the instance, you need to manually copy that data to more persistent storage, such as an Amazon EBS volume, an Amazon S3
bucket, or an Amazon EFS file system. There are some events that can result in your data not persisting throughout the lifetime of the instance. The following table
indicates whether data on instance store volumes is persisted during specific events, for both virtualized and bare metal instances1. References: Amazon EC2

A company is planning to migrate to the AWS Cloud. The company is conducting organizational transformation and wants to become more responsive to customer
inquiries and feedback.
Which tasks should the company perform to meet these requirements, according to the AWS Cloud Adoption Framework (AWS CAF)? (Select TWO.)
Answer: AC
Explanation:
Realigning teams to focus on products and value streams, and using agile methods to rapidly iterate and evolve are tasks that the company should perform to
meet the requirements of becoming more responsive to customer inquiries and feedback, according to the AWS Cloud Adoption Framework (AWS CAF). AWS
CAF organizes guidance into six areas of focus, called perspectives: business, people, governance, platform, security, and operations. Each perspective is divided
into capabilities, which describe the skills and processes to execute the transition effectively. The people perspective helps you prepare your organization for cloud
adoption, and includes capabilities such as organizational change management, staff skills and readiness, and organizational alignment. The business perspective
helps you align IT strategy with business strategy, and includes capabilities such as business case development, value proposition, and product ownership.
Creating new value propositions with new products and services is a task that belongs to the business perspective, but it is not directly related to the requirement
of becoming more responsive to customer inquiries and feedback. Using a new data and analytics platform to create actionable insights is a task that belongs to
the platform perspective, which helps you design, implement, and optimize the architecture of the AWS environment. However, it is also not directly related to the
requirement of becoming more responsive to customer inquiries and feedback. Migrating and modernizing legacy infrastructure is a task that belongs to the
operations perspective, which helps you enable, run, use, operate, and recover IT workloads to the level agreed upon with your business stakeholders. However, it
is also not directly related to the requirement of becoming more responsive to customer inquiries and feedback.

Answer: AB
Explanation:
These are two scenarios that represent the concept of elasticity on AWS. Elasticity means the ability to adjust the resources and capacity of the system in
response to changes in demand or environment. Scaling the number of Amazon EC2 instances based on traffic means using services such as AWS Auto Scaling
or Elastic Load Balancing to add or remove instances as the traffic increases or decreases. Resizing Amazon RDS instances as business needs change means
using the Amazon RDS console or API to modify the instance type, storage type, or storage size of the database as the workload grows or shrinks. You can learn
more about the concept of elasticity on AWS from [this webpage] or [this digital course].
