You need to implement the monitoring of SalesSQLDb1. The solution must meet the technical
requirements.

How should you collect and stream metrics? To answer, select the appropriate options in the answer
area.

NOTE: Each correct selection is worth one point.

www.authorizedumps.com
Questions & Answers PDF Page 10

Answer:
Explanation:

Box 1: The server, the elastic pool, and the database

Senario:

SalesSQLDb1 is in an elastic pool named SalesSQLDb1Pool.

Litware technical requirements include: all SQL Server and Azure SQL Database metrics related to
CPU and storage usage and limits must be analyzed by using Azure built-in functionality.

Box 2: Azure Event hubs

Scenario: Migrate ManufacturingSQLDb1 to the Azure virtual machine platform.

Event hubs are able to handle custom metrics.

Incorrect Answers:

Azure Log Analytics

Azure metric and log data are sent to Azure Monitor Logs, previously known as Azure Log Analytics,
directly by Azure. Azure SQL Analytics is a cloud only monitoring solution supporting streaming of
diagnostics telemetry for all of your Azure SQL databases.

www.authorizedumps.com
Questions & Answers PDF Page 11

However, because Azure SQL Analytics does not use agents to connect to Azure Monitor, it does not
support monitoring of SQL Server hosted on-premises or in virtual machines.

Question: 4

You need to identify the cause of the performance issues on SalesSQLDb1.

Which two dynamic management views should you use? Each correct answer presents part of the
solution.

B. sys.dm_exec_compute_node_errors

C. sys.dm_exec_requests

D. sys.dm_cdc_errors

E. sys.dm_pdw_nodes_os_wait_stats

F. sys.dm_tran_locks

Answer: AE
Explanation:

SalesSQLDb1 experiences performance issues that are likely due to out-of-date statistics and
frequent blocking queries.

A: Use sys.dm_pdw_nodes_tran_locks instead of sys.dm_tran_locks from Azure Synapse Analytics

E: Example:

The following query will show blocking information.

www.authorizedumps.com
Questions & Answers PDF Page 12

SELECT

t1.resource_type,

t1.resource_database_id,

t1.resource_associated_entity_id,

t1.request_mode,

t1.request_session_id,

t2.blocking_session_id

FROM sys.dm_tran_locks as t1

INNER JOIN sys.dm_os_waiting_tasks as t2

ON t1.lock_owner_address = t2.resource_address;

Note: Depending on the system you’re working with you can access these wait statistics from one of
three locations:

sys.dm_os_wait_stats: for SQL Server

sys.dm_db_wait_stats: for Azure SQL Database

sys.dm_pdw_nodes_os_wait_stats: for Azure SQL Data Warehouse

Incorrect Answers:

F: sys.dm_tran_locks returns information about currently active lock manager resources in SQL
Server 2019 (15.x). Each row represents a currently active request to the lock manager for a lock that
has been granted or is waiting to be granted.

Instead use sys.dm_pdw_nodes_tran_locks.

Question: 5

HOTSPOT

You need to recommend a configuration for ManufacturingSQLDb1 after the migration to Azure. The
solution must meet the business requirements.

What should you include in the recommendation? To answer, select the appropriate options in the
answer area.

NOTE: Each correct selection is worth one point.

Answer:
Explanation:

www.authorizedumps.com
Questions & Answers PDF Page 14

Scenario: Business Requirements

Litware identifies business requirements include: meet an SLA of 99.99% availability for all Azure
deployments.

Box 1: Cloud witness

If you have a Failover Cluster deployment, where all nodes can reach the internet (by extension of
Azure), it is recommended that you configure a Cloud Witness as your quorum witness resource.

Box 2: Azure Basic Load Balancer

Microsoft guarantees that a Load Balanced Endpoint using Azure Standard Load Balancer, serving two
or more Healthy Virtual Machine Instances, will be available 99.99% of the time.

Note: There are two main options for setting up your listener: external (public) or internal. The
external (public) listener uses an internet facing load balancer and is associated with a public Virtual
IP (VIP) that is accessible over the internet. An internal listener uses an internal load balancer and
only supports clients within the same Virtual Network.

Question: 7

www.authorizedumps.com
Questions & Answers PDF Page 16

HOTSPOT

You need to recommend the appropriate purchasing model and deployment option for the 30 new
databases. The solution must meet the technical requirements and the business requirements.

What should you recommend? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Answer:
Explanation:

www.authorizedumps.com
Questions & Answers PDF Page 17

Box 1: DTU

Scenario:

The 30 new databases must scale automatically.

Once all requirements are met, minimize costs whenever possible.

You can configure resources for the pool based either on the DTU-based purchasing model or the
vCore-based purchasing model.

In short, for simplicity, the DTU model has an advantage. Plus, if you’re just getting started with Azure
SQL Database, the DTU model offers more options at the lower end of performance, so you can get
started at a lower price point than with vCore.

Box 2: An Azure SQL database elastic pool

Azure SQL Database elastic pools are a simple, cost-effective solution for managing and scaling
multiple databases that have varying and unpredictable usage demands. The databases in an elastic
pool are on a single server and share a set number of resources at a set price. Elastic pools in Azure
SQL Database enable SaaS developers to optimize the price performance for a group of databases
within a prescribed budget while delivering performance elasticity for each database.

Overview

Existing Environment

Contoso, Ltd. is a financial data company that has 100 employees. The company delivers financial
data to customers.

Active Directory

Contoso has a hybrid Azure Active Directory (Azure AD) deployment that syncs to on-premises Active
Directory.

Database Environment

Contoso has SQL Server 2017 on Azure virtual machines shown in the following table.

www.authorizedumps.com
Questions & Answers PDF Page 26

SQL1 and SQL2 are in an Always On availability group and are actively queried. SQL3 runs jobs,
provides historical data, and handles the delivery of data to customers.

The on-premises datacenter contains a PostgreSQL server that has a 50-TB database.

Current Business Model

Contoso uses Microsoft SQL Server Integration Services (SSIS) to create flat files for customers. The
customers receive the files by using FTP.

Requirements

Planned Changes

Contoso plans to move to a model in which they deliver data to customer databases that run as
platform as a service (PaaS) offerings. When a customer establishes a service agreement with
Contoso, a separate resource group that contains an Azure SQL database will be provisioned for the
customer. The database will have a complete copy of the financial data. The data to which each
customer will have access will depend on the service agreement tier. The customers can change tiers
by changing their service agreement.

The estimated size of each PaaS database is 1 TB.

Contoso plans to implement the following changes:

www.authorizedumps.com
Questions & Answers PDF Page 27

Move the PostgreSQL database to Azure Database for PostgreSQL during the next six months.

Upgrade SQL1, SQL2, and SQL3 to SQL Server 2019 during the next few months.

Start onboarding customers to the new PaaS solution within six months.

Business Goals

Contoso identifies the following business requirements:

Use built-in Azure features whenever possible.

Minimize development effort whenever possible.

Minimize the compute costs of the PaaS solutions.

Provide all the customers with their own copy of the database by using the PaaS solution.

Provide the customers with different table and row access based on the customer’s service
agreement.

In the event of an Azure regional outage, ensure that the customers can access the PaaS solution
with minimal downtime. The solution must provide automatic failover.

Ensure that users of the PaaS solution can create their own database objects but he prevented from
modifying any of the existing database objects supplied by Contoso.

Technical Requirements

Contoso identifies the following technical requirements:

Users of the PaaS solution must be able to sign in by using their own corporate Azure AD
credentials or have Azure AD credentials supplied to them by Contoso. The solution must avoid using
the internal Azure AD of Contoso to minimize guest users.

All customers must have their own resource group, Azure SQL server, and Azure SQL database. The

www.authorizedumps.com
Questions & Answers PDF Page 28

deployment of resources for each customer must be done in a consistent fashion.

Users must be able to review the queries issued against the PaaS databases and identify any new
objects created.

Downtime during the PostgreSQL database migration must be minimized.

Monitoring Requirements

Contoso identifies the following monitoring requirements:

Notify administrators when a PaaS database has a higher than average CPU usage.

Use a single dashboard to review security and audit data for all the PaaS databases.

Use a single dashboard to monitor query performance and bottlenecks across all the PaaS
databases.

Monitor the PaaS databases to identify poorly performing queries and resolve query performance
issues automatically whenever possible.

PaaS Prototype

During prototyping of the PaaS solution in Azure, you record the compute utilization of a customer’s
Azure SQL database as shown in the following exhibit.

Question: 17

What should you implement to meet the disaster recovery requirements for the PaaS solution?

A. Availability Zones

B. failover groups

C. Always On availability groups

D. geo-replication

Answer: B
Explanation:

Scenario: In the event of an Azure regional outage, ensure that the customers can access the PaaS
solution with minimal downtime. The solution must provide automatic failover.

The auto-failover groups feature allows you to manage the replication and failover of a group of
databases on a server or all databases in a managed instance to another region. It is a declarative
abstraction on top of the existing active geo-replication feature, designed to simplify deployment
and management of geo-replicated databases at scale. You can initiate failover manually or you can
delegate it to the Azure service based on a user-defined policy.

The latter option allows you to automatically recover multiple related databases in a secondary
region after a catastrophic failure or other unplanned event that results in full or partial loss of the
SQL Database or SQL Managed Instance availability in the primary region.

Overview

ADatum Corporation is a retailer that sells products through two sales channels: retail stores and a
website.

Existing Environment

ADatum has one database server that has Microsoft SQL Server 2016 installed. The server hosts three
mission-critical databases named SALESDB, DOCDB, and REPORTINGDB.

SALESDB collects data from the stores and the website.

DOCDB stores documents that connect to the sales data in SALESDB. The documents are stored in
two different JSON formats based on the sales channel.

REPORTINGDB stores reporting data and contains several columnstore indexes. A daily process
creates reporting data in REPORTINGDB from the data in SALESDB. The process is implemented as a
SQL Server Integration Services (SSIS) package that runs a stored procedure from SALESDB.

Requirements

Planned Changes

ADatum plans to move the current data infrastructure to Azure. The new infrastructure has the
following requirements:

www.authorizedumps.com
Questions & Answers PDF Page 37

Migrate SALESDB and REPORTINGDB to an Azure SQL database.

Migrate DOCDB to Azure Cosmos DB.

The sales data, including the documents in JSON format, must be gathered as it arrives and analyzed
online by using Azure Stream Analytics. The analytics process will perform aggregations that must be
done continuously, without gaps, and without overlapping.

As they arrive, all the sales documents in JSON format must be transformed into one consistent
format.

Azure Data Factory will replace the SSIS process of copying the data from SALESDB to REPORTINGDB.

Technical Requirements

The new Azure data infrastructure must meet the following technical requirements:

Data in SALESDB must encrypted by using Transparent Data Encryption (TDE). The encryption must
use your own key.

SALESDB must be restorable to any given minute within the past three weeks.

Real-time processing must be monitored to ensure that workloads are sized properly based on actual
usage patterns.

Missing indexes must be created automatically for REPORTINGDB.

Disk IO, CPU, and memory usage must be monitored for SALESDB.

Question: 20

Which windowing function should you use to perform the streaming aggregation of the sales data?

A. Sliding

B. Hopping

www.authorizedumps.com
Questions & Answers PDF Page 38

C. Session

D. Tumbling

Answer: D
Explanation:

Scenario: The sales data, including the documents in JSON format, must be gathered as it arrives and
analyzed online by using Azure Stream Analytics. The analytics process will perform aggregations
that must be done continuously, without gaps, and without overlapping.
