Exam DP-300: Administering Microsoft Azure SQL Solutions Part -2


 1) You need to recommend a high-availability and disaster recovery (HA/DR) strategy for a SQL Server on Azure Virtual Machines instance. The solution must meet the following requirements:

  • All databases, including system databases, must be protected.
  • SQL Server Agent jobs must be protected.
  • Downtime must be minimized.
  • The failover process must be done automatically.

What should you include in the recommendation?


       a. an Always On availability group

       b. an Always On failover cluster instance

       c. log shipping

       d. transactional replication


You should recommend an Always On failover cluster instance because this feature protects the entire instance. A SQL Server on Azure Virtual Machines instance is the entire installation of Microsoft SQL Server, such as binaries and all the objects inside the instance, including logins, SQL Server Agent jobs, and databases. Instance-level protection means that the entire instance is accounted for in the availability feature.

An Always On availability group works at the database level rather than the instance level. Transactional replication cannot replicate system databases, and neither transactional replication nor log shipping allow you to perform automatic failover.




 2) You have an Azure SQL Database named db1.

You need to configure a backup strategy to ensure that the db1 has backups retained for six years.

What should you configure?


       a. differential backup frequency

       b. long-term retention

       c. point-in-time-restore


A long-term retention policy allows you to specify how many weeks, months, and years a backup should be kept. The maximum time is 10 years.

A point-in-time-restore policy only allow you to keep backups for 35 days, and a differential backup frequency policy specifies how often you want differential backup to be taken.

 3) You have an Azure SQL Database.

You need to configure high availability for the database in the event of a regional outage.

Which two features can you use? Each correct answer presents a complete solution.


       a. active geo-replication

       b. Always On availability groups

       c. auto-failover groups

       d. long-term backup retention


Active geo-replication creates a secondary database replica in another region that is asynchronously kept up-to-date, and the auto-failover groups feature allows you to manage the replication and failover of some or all databases on a logical server to another region.

The Always On availability groups feature is a high-availability and disaster recovery (HA/DR) solution, but it is not used for Azure SQL Database. Long-term backup retention stores database backups in Azure Blob storage.

 4) You have an Azure SQL Managed Instance that hosts five databases.

You need to configure disaster recovery for the databases in the event of a regional outage.

What can you use?


       a. active geo-replication

       b. Always On availability groups

       c. auto-failover groups

       d. long-term backup retention


The auto-failover groups feature allows you to manage the replication and failover of some or all databases on a logical server to another region, which allows you to configure high availability in the event of a regional outage.

Active geo-replication creates a secondary database replica in another region, but it is asynchronously kept up-to-date for Azure SQL Database. The Always On availability groups feature is a high-availability and disaster recovery (HA/DR) solution, but it is not for Azure SQL Database. Long-term backup retention stores database backups in Azure Blob storage.


5) You have an Azure subscription that contains four virtual machines. All the virtual machines have Microsoft SQL Server 2019 installed.

A distributed availability group named DG1 has a replica on each virtual machine.

You need to enable monitoring for DG1. The solution must help diagnose performance issues.

What should you use?


       a. SQL Database Advisor

       b. Query Performance Insight

       c. Azure SQL Insights


Azure SQL Insights is a comprehensive solution for monitoring any product in the Azure SQL family.

Query Performance Insight provides intelligent query analysis for single and pooled databases but cannot provide information about a distributed availability group.

SQL Database Advisor provides performance recommendations but cannot provide information about a distributed availability group.




6) You have an Azure subscription that contains five virtual machines. The virtual machines host a Microsoft SQL Server 2019 Always On availability group named AG1.

You need to enable monitoring for AG1. The solution must ensure that you can monitor the health of AG1 and diagnose performance issues.

What should you use?


       a. Intelligent Insights

       b. Query Performance Insight

       c. SQL Database Advisors

       d. SQL Insights


SQL Insights is a comprehensive solution for monitoring any product in the Azure SQL family. As such, it allows you to monitor the health of AG1 and diagnose any performance issues.

Query Performance Insight provides intelligent query analysis for single and pooled databases, SQL Database Advisor provides performance recommendations, and Intelligent Insights uses built-in intelligence to continuously monitor database usage through artificial intelligence (AI) and detect disruptive events that cause poor performance.

7) You have an Azure subscription.

You plan to deploy 100 Azure SQL Databases.

You need to automate the deployment. The solution must be parameterizable, repeatable, and be able to be versioned in source control.

Which three components can you use? Each correct answer presents a complete solution.


  • Azure Cloud Shell
  • Azure Policy
  • Azure PowerShell scripts
  • Azure Resource Manager (ARM) templates
  • Bicep templates

ARM templates, Bicep templates, and PowerShell scripts can all be parameterized and versioned.

Cloud Shell is an interactive, authenticated, browser-accessible shell, and Azure Policy helps to enforce organizational standards and to assess compliance at-scale.

8) You have an Azure subscription. The subscription contains several Azure SQL Databases that support departmental applications. You plan to use elastic jobs to periodically execute T-SQL-based maintenance tasks against all the databases. 

What should you do first? 

  • Create an Azure SQL Database.
  • Create an Azure SQL elastic pool server.
  • Create an Elastic Job agent.
  • Create the Elastic Job targets.


You need to create an Azure SQL Database to keep the elastic job configuration.

The Elastic Job agent can be configured once the database and the elastic job configuration is prepared.

You cannot create Elastic Job targets until you have an agent.

You do not need to create an elastic pool server for this task.

9) You have an on-premises Microsoft SQL Server 2016 instance that uses FileTable.

You need to migrate the instance to Azure. The solution must support the existing application code.

What should you use?


       a. Azure SQL Database HyperScale

       b. Azure SQL Database serverless

       c. Azure SQL Managed Instance

       d. SQL Server on Azure Virtual Machines


SQL Server on Azure Virtual Machines supports FileTable. It can be used to migrate the instance to Azure and support the existing application code.

Azure SQL Database serverless and Azure SQL Database Hyperscale are tiers of Azure SQL Database that do not support FileTable. Azure SQL Managed Instance does not support FileTable.

10) You have a fact table that contains 500 million rows. The table has a clustered index. Most queries select data from the current week and rarely select data that is more than a month old.

Queries against the table are very slow.

You need to recommend a solution that will improve the performance of the majority of the queries against the table.

What should you include in the recommendation?

       a. an in-memory table

       b. page compression

       c. row compression

       d. table partitioning

The data of partitioned tables and indexes are divided into units that might be spread across more than one filegroup in a database or stored in a single filegroup. The partition that contains the most current data does not block any queries that are related to old data, so this will benefit the performance.

Row and page compression changes the internal table storage, but it does not help solve the performance issues. The in-memory table is best for transactional workloads, and the fact table is the analytical workload.

11) You have several databases in an Azure SQL Managed Instance that uses the General Purpose vCore service tier.

You discover high latency in some of the database files.

What should you do to reduce latency?


       a. Add more files to the database.

       b. Add more virtual cores to the instance.

       c. Increase the file size.

       d. Change the service tier.


You should increase the file size to improve performance. If you have a file that is up to 128 GB, then you can have up to 500 IOPS. If you change the file size to 1 TB, then you can have up to 5,000 IOPS. 

You should not add more vCores to the instance in the General Purpose tier, as this will not change the available IOPS. Adding more files to the database also does not help, as the number of available IOPS is calculated per file size, not by the number of files. Changing the service tier will change the type of CPU, the maximum file size, and the amount of memory reserved per CPU. 


12) You are planning a migration from on-premises Microsoft SQL Server to Azure using Azure Database Migration Service.

You need to keep databases online during the migration.

Which two services can you use? Each correct answer presents a complete solution.

  •  Azure Cosmos DB
  • Azure SQL Database
  • Azure SQL Managed Instance
  • SQL Server on Azure Virtual Machines

SQL Server on Azure Virtual Machines and Azure SQL Managed Instance both support online migration. 

Azure SQL Database does not support online migration and Azure CosmosDB is not a relational database. 


13) You have an on-premises Microsoft SQL Server 2019 instance that hosts 10 databases.

You plan to migrate the databases to Azure SQL Database.

You need to validate the compatibility of the databases with Azure SQL Database.

Which two tools can you use? Each correct answer presents a complete solution.

 

  • App and Data Modernization Readiness Tool
  • Data Migration Assistant (DMA)
  • Microsoft Assessment and Planning (MAP) Toolkit for SQL Server
  • the Azure Migrate Discovery and assessment tool
  • the SQL Server Management Studio (SSMS) Copy Database Wizard

DMA will assess the database for compatibility. The Azure Migrate Discovery and assessment tool discovers and assesses on-premises VMware virtual machines, Hyper-V virtual machines, and physical servers for migration to Azure.

The MAP toolkit provides an inventory of the Microsoft Platform. The Copy Database Wizard is used for copying databases. The App and Data Modernization Readiness Tool is used to help customers evaluate their business strategies.





14) You plan to configure Extended Events monitoring to gather information about queries.

You need to add information about the session_id to all events.

What should you configure for the extended event session?

       a. action

       b. package

       c. predicate

       d. target


An action is a programmatic response or series of responses to an event. Actions are bound to an event, and each event may have a unique set of actions. Actions are global fields. Configuring an action allows you to add the required information to all events.

Targets process events, predicates are a set of logical rules used to evaluate events when they are processed, and a package is a container for Microsoft SQL Server Extended Events objects.



15) You have an Azure SQL Database.

Users report poor performance of the database overnight.

You need to identify the cause of the performance issue.

What should you do?

       a. Query the sys.dm_exec_requests dynamic management view.

       b. Use Auditing for Azure SQL Database to investigate.

       c. Use Query Store to investigate the metrics.

       d. Use SQL Server Profiler to gather a trace.


Using Query Store will enable a historical investigation, which will allow you to look at the metrics to identify the cause of the poor performance.

sys.dm_exec_requests returns information about currently running requests, but it does not allow you to look into past performance issues. Auditing for Azure SQL Database tracks database events. A SQL Server Profile trace will gather information about current activity, but it does not allow you to do a historical investigation of the issue.


16) You have an Azure SQL Database.

You need to troubleshoot blocking and deadlocking performance issues.

Which two features can you use? Each correct answer presents a complete solution.

  • an Azure SQL Database ledger
  • Extended Events
  • Microsoft Defender for SQL
  • Query Store
  • SQL Insights
Extended Events and SQL Insights can both capture blocking and deadlocking metrics that can be used to investigate and troubleshoot the performance issues.

Query Store does not capture blocking and deadlocking metrics, Azure SQL Defender surfaces database vulnerabilities, and an Azure SQL Database ledger incrementally captures the state of the database.

17) You have an Azure subscription that contains five Azure SQL Databases.

You need to configure SQL Insights.

What should you do first?

       a. Configure automatic tuning.

       b. Configure Extended Events.

       c. Create a monitoring profile.

       d. Enable Azure SQL Auditing.


Creating a monitoring profile is the first requirement to configuring SQL Insights.

Automatic tuning uses AI to provide peak performance. Azure SQL Auditing tracks database events and records them. Extended Events is a lightweight performance monitoring system.



18) You have an Azure SQL Managed Instance.

You discover a high number of blocking queries during peak business hours.

You need to investigate the root cause of the blocking queries.

Which two dynamic management views should you query? Each correct answer presents a complete solution.
  • sys.dm_exec_query_stats
  • sys.dm_exec_requests
  • sys.dm_exec_sessions_wait_stats
  • sys.dm_os_waiting_tasks
You should query the sys.dm_exec_requests view to get the blocking session ID information. This view returns information about each request that is executing in Microsoft SQL Server. You should also use sys.dm_os_waiting_tasks because the information is related to current connections and sessions. There is blocking session ID information that can be used to identify the root of the issue.

The sys.dm_exec_sessions_wait_stats view presents historical information about the waits that occurred on the server, and the sys.dm_exec_query_stats view returns aggregate performance statistics for cached query plans in SQL Server.



19) You have an Azure SQL Managed Instance that contains databases.

One of the databases experiences excessive blocking.

You need to identify which session is causing the blocking.

Which dynamic management view should you query?

       a. sys.dm_exec_query_stats

       b. sys.dm_exec_requests

       c. sys.dm_exec_session_wait_stats

       d. sys.dm_exec_sessions


sys.dm_exec_requests returns information about each request that is executing in Microsoft SQL Server. One of the columns exposed by this view is blocking_session_id.

sys.dm_exec_sessions returns one row per authenticated session in SQL Server. This view does not return information about blocking issues.

sys.dm_exec_query_stats returns aggregate performance statistics for cached plans in SQL Server.

sys.dm_exec_session_waits returns information about all the waits encountered by threads that are executed for each session.


20) You run the DBCC CHECKDB command for a production database. The command shows errors in several nonclustered indexes.

You need to repair the indexes and ensure the integrity of the database after the operation has complete.

Which parameter should you specify in the DBCC CHECKDB command?

       a. REPAIR_ALLOW_DATA_LOSS

       b. REPAIR_REBUILD

       c. REPAIR_FAST


Adding the REPAIR_REBUILD option to the DBCC CHECKDB command performs repairs that have no possibility of data loss. This option may include quick repairs, such as repairing missing rows in nonclustered indexes, and more time-consuming repairs, such as rebuilding an index.

The REPAIR_FAST option maintains syntax for backward compatibility only. No repair actions are performed. The REPAIR_ALLOW_DATA_LOSS option can introduce some data loss in the database.



21) You have an Azure SQL Database named db1.

You need to provide access to db1 for a Microsoft Entra ID user .

What should you do?

       a. In db1, run the CREATE USER statement with the FROM LOGIN option.

       b. In db1, run the CREATE USER statement with the FROM EXTERNAL PROVIDER option.

       c. In the master database, run the CREATE LOGIN statement with the FROM EXTERNAL PROVIDER option.

       d. In the master database, run the CREATE LOGIN statement with the WITH PASSWORD option.



22) You have an Azure SQL Database logical server named Instance1.

You create a user named User1 in the master database of Instance1.

You need to ensure that User1 can create and delete databases attached to Instance1. The solution must follow the principle of least privilege.

Which role should you assign to User1?

       a. db_ddladmin

       b. dbmanager

       c. db_owner

       d. loginmanager


Members of the dbmanager role can create databases.

Members of the db_owner role can perform all activities at the database level.

Members of the db_ddladmin role can run any DDL statements.

Members of the loginmanager can create and delete logins.



23) You create a stored procedure that runs dynamic SQL code to select data from a table named Sales.

All users have execute permissions to the stored procedure.

What should you do to ensure that the users can run the procedure without errors?


       a. Add a WITH RECOMPILE clause to the stored procedure.

       b. Add the SELECT permission to the Sales table for the users.

       c. Add an EXECUTE AS [owner] clause to the stored procedure.


You should add the SELECT permission to the Sales table because executing dynamic SQL code requires that the caller has all the necessary permissions to the objects that are called in the code.

Using the EXECUTE AS [owner] clause or the WITH RECOMPILE clause does not ensure that the caller has all the necessary permissions to the objects that are called in the code.

24) You have an Azure SQL Database named db1 that contains a table named Sales.

You need to encrypt data in a column named CreditCard in the Sales table.

Which two actions should you perform before you can encrypt the data? Each correct answer presents part of the solution.

       a. Create a certificate in the db1 database.

       b. Create a certificate in the master database.

       c. Create a symmetric key encrypted by a certificate.

       d. Create an asymmetric key encrypted by a certificate.


The certificate created in db1 will be used to encrypt a symmetric key, which, in turn, will be used to protect data in the CreditCard column in the Sales table. The column containing encrypted data must be varbinary column.

A symmetric key, not an asymmetric key, is required for this operation. Creating the certificate in the master database would not work, as the certificate that is needed for encryption must be created in the user database.


25) You have an Azure SQL managed instance Azure SQL Managed Instance that hosts a database.

The database contains a column named Column1 that stores confidential information.

You need to audit access to Column1. The solution must meet the following requirements:

Retain audit data for at least eighteen years.

Minimize administrative effort.

Which three actions should you perform? Each correct answer presents part of the solution.

  • Apply a sensitivity classification to the column.
  • Configure a Log Analytics audit log destination.
  • Configure a Storage audit log destination.
  • Enable Always Encrypted for the column.
  • Enable Azure SQL Auditing.
  • Enable Transparent Data Encryption (TDE).

Azure SQL Auditing needs to be enabled to monitor access. A storage account allows unlimited retention. The column needs a classification label so that access is audited.

Log Analytics has a maximum retention limit of seven years, Always Encrypted is used to protect data in use or in transit, and TDE encrypts data files.


26) You have 20 Azure SQL databases provisioned by using the vCore purchasing model.
You plan to create an Azure SQL Database elastic pool and add the 20 databases.
Which three metrics should you use to size the elastic pool to meet the demands of your workload? Each correct answer presents part of the solution.


       a. total size of all the databases

       b. geo-replication support

       c. number of concurrently peaking databases * peak CPU utilization per database

       d. loginmaximum number of concurrent sessions for all the databases

       e. total number of databases * average CPU utilization per database


27) You have SQL Server 2019 on an Azure virtual machine that contains an SSISDB database.
A recent failure causes the master database to be lost.
You discover that all Microsoft SQL Server integration Services (SSIS) packages fail to run on the virtual machine.
Which four actions should you perform in sequence to resolve the issue? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct.

Step 1: Attach the SSISDB database

Step 2: Turn on the TRUSTWORTHY property and the CLR property

If you are restoring the SSISDB database to an SQL Server instance where the SSISDB catalog was never created, enable common language runtime (clr)

Step 3: Open the master key for the SSISDB database

Restore the master key by this method if you have the original password that was used to create SSISDB. open master key decryption by password = 'LS1Setup!' --'Password used when creating SSISDB'

Alter Master Key Add encryption by Service Master Key

Step 4: Encrypt a copy of the master key by using the service master key

28) You have an Azure SQL database that contains a table named factSales. FactSales contains the columns shown in the following table.


FactSales has 6 billion rows and is loaded nightly by using a batch process. You must provide the greatest reduction in space for the database and maximize performance.

Which type of compression provides the greatest space reduction for the database?

       a. page compression

       b. row compression

       c. columnstore compression

       d. columnstore archival compression


29) You have a Microsoft SQL Server 2019 database named DB1 that uses the following database-level and instance-level features.

What feature should be removed or replaced before DB1 can be migrated?

       a. Clustered columnstore indexes

       b. PolyBase

       c. Change tracking

       d. Automatic tuning


30) You have a Microsoft SQL Server 2019 instance in an on-premises datacenter. The instance contains a 4-TB database named DB1.

You plan to migrate DB1 to an Azure SQL Database managed instance.

What should you use to minimize downtime and data loss during the migration?

       a. distributed availability groups

       b. database mirroring

       c. Always On Availability Group

       d. Azure Database Migration Service


Azure Database Migration Service can do online migrations with minimal downtime.

Reference:

https://docs.microsoft.com/en-us/azure/dms/dms-overview 


31) You have an on-premises Microsoft SQL Server 2016 server named Server1 that contains a database named DB1.

You need to perform an online migration of DB1 to an Azure SQL Database managed instance by using Azure Database Migration Service.

How should you configure the backup of DB1? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Hot Area:

Box 1: Full and log backups only

Make sure to take every backup on a separate backup media (backup files). Azure Database Migration Service doesn't support backups that are appended to a single backup file. Take full backup and log backups to separate backup files.


Box 2: WITH CHECKSUM -

Azure Database Migration Service uses the backup and restore method to migrate your on-premises databases to SQL Managed Instance. Azure Database

Migration Service only supports backups created using checksum.

Incorrect Answers:

NOINIT Indicates that the backup set is appended to the specified media set, preserving existing backup sets. If a media password is defined for the media set, the password must be supplied. NOINIT is the default.


UNLOAD -

Specifies that the tape is automatically rewound and unloaded when the backup is finished. UNLOAD is the default when a session begins.
