Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q90-Q95):

NEW QUESTION # 90
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. Decrease by half the value of Data Flush Interval
B. Double the value of Data Flush interval
C. Double the value of Statistics Collection Interval
D. Decrease by half the value of Statistics Collection interval

Answer: C

Explanation:
To avoid Query Store transitioning to read-only state, the runtime statistics for the Last Stale Query Threshold days must fit in the defined Max Size (MB). If the Statistics Collection Interval is increased then less space will be used for the persisted runtime statistics and there will be more free space for new data. The Data Flush Interval can delay the transitioning to read-only state, but not minimize the possibility it occurs.

NEW QUESTION # 91

NEW QUESTION # 92
You have SQL Server on an Azure virtual machine that contains a database named Db1.
You need to enable automatic tuning for Db1.
How should you complete the statements? To answer, select the appropriate answer in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation

Box 1: SET AUTOMATIC_TUNING = AUTO
To enable automatic tuning on a single database via T-SQL, connect to the database and execute the following query:
ALTER DATABASE current SET AUTOMATIC_TUNING = AUTO
Setting automatic tuning to AUTO will apply Azure Defaults.
Box 2: SET AUTOMATIC_TUNING (FORCE_LAST_GOOD_PLAN = ON)
To configure individual automatic tuning options via T-SQL, connect to the database and execute the query such as this one:
ALTER DATABASE current SET AUTOMATIC_TUNING (FORCE_LAST_GOOD_PLAN = ON) Setting the individual tuning option to ON will override any setting that database inherited and enable the tuning option. Setting it to OFF will also override any setting that database inherited and disable the tuning option.

NEW QUESTION # 93
You have two on-premises Microsoft SQL Server 2019 instances named SQL1 and SQL2.
You need to migrate the databases hosted on SQL 1 to Azure. The solution must meet the following requirements:
The service that hosts the migrated databases must be able to communicate with SQL2 by using linked server connections.
Administrative effort must be minimized.
What should you use to host the databases?

A. Azure SQL Managed Instance
B. an Azure SQL Database elastic pool
C. SQL Server on Azure Virtual Machines
D. a single Azure SQL database

Answer: A

NEW QUESTION # 94
You have an Azure virtual machine based on a custom image named VM1.
VM1 hosts an instance of Microsoft SQL Server 2019 Standard.
You need to automate the maintenance of VM1 to meet the following requirements:
- Automate the patching of SQL Server and Windows Server.
- Automate full database backups and transaction log backups of the
databases on VM1.
- Minimize administrative effort.
What should you do first?

A. Enable a system-assigned managed identity for VM1
B. Register VM1 to the Microsoft.Sql resource provider
C. Register VM1 to the Microsoft.SqlVirtualMachine resource provider
D. Install an Azure virtual machine Desired State Configuration (DSC) extension on VM1

Answer: C

Explanation:
Automated Patching depends on the SQL Server infrastructure as a service (IaaS) Agent Extension. The SQL Server IaaS Agent Extension (SqlIaasExtension) runs on Azure virtual machines to automate administration tasks. The SQL Server IaaS extension is installed when you register your SQL Server VM with the SQL Server VM resource provider.
To utilize the SQL IaaS Agent extension, you must first register your subscription with the Microsoft.SqlVirtualMachine provider, which gives the SQL IaaS extension the ability to create resources within that specific subscription.
