Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q416-Q421):

NEW QUESTION # 416
Hotspot Question
You have an Azure SQL managed instance named Server1 and an Azure Blob Storage account named storage1 that contains Microsoft SQL Server database backup files.
You plan to use Log Replay Service to migrate the backup files from storage1 to Server1. The solution must use the highest level of security when connecting to storage1.
Which PowerShell cmdlet should you run, and which parameter should you specify to secure the connection? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

NEW QUESTION # 417
You have the on premises networks shown in the following table.

You have an Azure subscription that contains an Azure SQL Database server named SQL1. SQL1 contains two databases named DB1 and DB2.
You need to configure access to DB1 and DB2. The solution must meet the following requirements:
Ensure that DB1 can be accessed only by users in Branch1.
Ensure that DB2 can be accessed only by users in Branch2.
Solution: You connect to DB1 and run the following command:
EXECUTE sp_set_firewall_rule ' Deny db1 users ' , ' 131.107.11.0 ' , ' 131.107.11.255 ' You connect to DB2 and run the following command:
EXECUTE sp_set_database_firewall_rule ' Deny db2 users ' , ' 131.107.10.0 ' , ' 131.107.10.255 ' Does this meet the goal?

A. Yes
B. No

Answer: B

NEW QUESTION # 418
You have an Azure Database for MySQL database. You have to identify which database queries are consuming the most resources.
Which of the following tool can be used for this requirement?

A. Metrics
B. Query Store
C. Alerts
D. Query Performance Insight

Answer: D

Explanation:
Query Performance Insight helps you to quickly identify what your longest-running queries are, how they change over time, and what kind of waits are affecting them.
Option A is incorrect since Query Store automatically captures a history of queries and runtime statistics, and it retains them for your review.
Option D is incorrect since this can only be used to alert someone if a metric goes beyond a threshold

NEW QUESTION # 419
You have a on-premises Microsoft SQL Server named SQL1 that hosts five databases.
You need to migrate the databases to an Azure SQL managed instance.
The solution must minimize downtime and prevent data loss.
What should you use?

A. log shipping
B. Always On availability groups
C. Backup and Restore
D. Database Migration Assistant

Answer: C

Explanation:
DMA does not support database migrations to Azure SQL Managed Instance. Recommendation is to use the Azure SQL migration extension for Azure Data Studio, which supports both online and offline database migrations to Azure SQL Managed Instance, but here we don't have the option "Azure SQL migration extension for Azure Data Studio".
https://learn.microsoft.com/en-us/sql/dma/dma-overview?view=sql-server-ver16#capabilities
Regarding log shipping to Managed Instance is not possible; it only supports the restore of full backups.

NEW QUESTION # 420
You have an Azure SQL database named sqldb1.
You need to minimize the possibility of Query Store transitioning to a read-only state.
What should you do?

A. Double the value of Data Flush interval
B. Decrease by half the value of Statistics Collection interval
C. Double the value of Statistics Collection Interval
D. Decrease by half the value of Data Flush Interval

Answer: D

Explanation:
The Max Size (MB) limit isn't strictly enforced. Storage size is checked only when Query Store writes data to disk. This interval is set by the Data Flush Interval (Minutes) option. If Query Store has breached the maximum size limit between storage size checks, it transitions to read-only mode.
Incorrect Answers:
C: Statistics Collection Interval: Defines the level of granularity for the collected runtime statistic, expressed in minutes. The default is 60 minutes. Consider using a lower value if you require finer granularity or less time to detect and mitigate issues. Keep in mind that the value directly affects the size of Query Store data.
