Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q200-Q205):

NEW QUESTION # 200
You are working on two projects named Project1 and Project2 that will each migrate an on-premises app to Azure. Project1 must meet the following requirements:
* Have access to the operating system of the database server that hosts the app.
* Have 25 TB of storage.
Project2 must meet the following requirements:
* Have change data capture (CDC) enabled
* Support instance-level SQL auditing.
* Support managed backups.
* Have 10 TB of storage.
* Offload reports.
You need to recommend an Azure SQL solution for the projects. The solution must minimize costs.
What should you include in the recommendation for each project? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:

Basic Concept: This question tests choosing the correct Azure migration approach by matching the source platform, target service, downtime tolerance, and administrative effort.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: Project1 must meet the following requirements: * Have access to the operating system of the database server that hosts the app.
Why the alternate choices are Wrong: The alternate selections would either use a migration tier that does not match the downtime requirement, choose a network resource that does not support the migration path, or add an unnecessary deployment component.

NEW QUESTION # 201
Drag and Drop Question
You have SQL Server on an Azure virtual machine named SQL1.
SQL1 has an agent job to back up all databases.
You add a user named dbadmin1 as a SQL Server Agent operator.
You need to ensure that dbadmin1 receives an email alert if a job fails.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation:
Step 1: Enable Database Mail
Database Mail must be enabled.
Step 2: Enable the email settings for the SQL Server Agent.
To send a notification in response to an alert, you must first configure SQL Server Agent to send mail.
Step 3: Create a job notification
Example:
-- adds an e-mail notification for the specified alert (Test Alert)
-- This example assumes that Test Alert already exists
-- and that Fran§ois Ajenstat is a valid operator name.
USE msdb ;
GO -
EXEC dbo.sp_add_notification -
@alert_name = N'Test Alert',
@operator_name = N'Fran§ois Ajenstat',
@notification_method = 1 ;
GO -

NEW QUESTION # 202
You have an Azure SQL database.
Users report that the executions of a stored procedure are slower than usual. You suspect that a regressed query is causing the performance issue.
You need to view the query execution plan to verify whether a regressed query is causing the issue. The solution must minimize effort.
What should you use?

A. Extended Events in Microsoft SQL Server Management Studio (SSMS)
B. Query Store in Microsoft SQL Server Management Studio (SSMS)
C. Query Performance Insight in the Azure portal
D. Performance Recommendations in the Azure portal

Answer: B

Explanation:
Use the Query Store Page in SQL Server Management Studio.
Query performance regressions caused by execution plan changes can be non-trivial and time consuming to resolve.
Since the Query Store retains multiple execution plans per query, it can enforce policies to direct the Query Processor to use a specific execution plan for a query. This is referred to as plan forcing. Plan forcing in Query Store is provided by using a mechanism similar to the USE PLAN query hint, but it does not require any change in user applications. Plan forcing can resolve a query performance regression caused by a plan change in a very short period of time.

NEW QUESTION # 203
You have a database on a SQL Server on Azure Virtual Machines instance.
The current state of Query Store for the database is shown in the following exhibit.

Answer:

Explanation:

Explanation
Graphical user interface, text Description automatically generated

You need to ensure that user1@contoso.com can create logins in SQLMI1 that map to Azure AD service principals.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Explanation:

1 - Grant SQLMI1 read access to Azure AD.
2 - Run CREATE LOGIN user1@.........
3 - Run ALTER SERVER ROLE securityadmin ADD MEMBER user1@contoso.com.
