Scenario: Authenticate database users by using Active Directory credentials.
The configuration steps include the following procedures to configure and use Azure Active Directory authentication.
* Create and populate Azure AD.
* Optional: Associate or change the active directory that is currently associated with your Azure Subscription.
* Create an Azure Active Directory administrator. (Step 1)
* Configure your client computers.
* Create contained database users in your database mapped to Azure AD identities. (Step 2)
* Connect to your database by using Azure AD identities. (Step 3)

質問 # 348
You have an Azure subscription.
You need to deploy a logical SQL server by using PowerShell. The solution must ensure that the logical SQL server can create Azure AD users and provide Transparent Data Encryption (TDE} with a customer-managed key.
How should you complete the command? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

正解：

解説：

Explanation:
" Assigned Identity " and " Key id " https://learn.microsoft.com/en-us/powershell/module/az.sql/new- azsqlserver?view=azps-10.2.0#code-try-3 Basic Concept: This question tests identity and authentication for Azure SQL and SQL Server workloads, including when to use contained users, directory identities, certificate validation, or authentication profiles.
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: You need to deploy a logical SQL server by using PowerShell.
Why the alternate choices are Wrong: The alternate actions fail because Entra authentication must be established at the server/administrator level first, then mapped to contained database users, and finally used by the client connection.


質問 # 349
You have an Azure SQL database.
You need to identify whether a delayed query execution is associated to a RESOURCE wait.
How should you complete the Transact -SQL statement? To answer, select the appropriate option in the answer area.

Drag and Drop Question
You have an Azure subscription that contains an Azure SQL managed instance named SQLMi1 and a SQL Agent job named Backupdb. Backupdb performs a daily backup of the databases hosted on SQLMi1.
You need to be notified by email if the 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.
NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.

正解：

解説：

Explanation:
Step 1: Enable Database Mail
If it isn't already enabled, first you would need to configure the Database Mail feature on SQL Managed Instance.
Box 2: Create an operator.
You can notify the operator that something happened with your SQL Agent jobs. An operator defines contact information for an individual responsible for the maintenance of one or more instances in SQL Managed Instance.
Box 3: Add a failure notification to the job,
You can then modify any SQL Agent job and assign operators that will be notified via email if the job completes, fails, or succeeds using SSMS or the following T-SQL script:
EXEC msdb.dbo.sp_update_job @job_name=N'Load data using SSIS',
@notify_level_email=3, -- Options are: 1 on succeed, 2 on failure, 3 on complete
@notify_email_operator_name=N'AzureSQLTeam';
