Explanation:

Step 1: 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 2: Create a job alert
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 Francois Ajenstat is a valid operator name.
USE msdb ;
GO
EXEC dbo.sp_add_notification
@alert_name = N ' Test Alert ' ,
@operator_name = N ' Francois Ajenstat ' ,
@notification_method = 1 ;
GO

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: You need to migrate DB1 to a vCore-based purchasing model by using the Azure Command-Line Interface (Azure CLI).
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.

The Email masking method, which exposes the first letter and replaces the domain with XXX.com using a constant string prefix in the form of an email address.
Example: [email protected]
Basic Concept: This question tests secure database administration, where the control must match the data state, access boundary, identity model, or compliance requirement.
Why B is Correct: From the Azure portal, set a sensitivity classification of Confidential for the Email column.
matches the expected DP-300 administration action. From the Azure portal, set a sensitivity classification of Confidential for the Email column. is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You need to prevent nonadministrative users from seeing the full email addresses in the Email column.
Why A is Wrong: From the Azure portal, set a mask on the Email column. is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It is not the right enforcement point for this case; the scenario needs the control that governs the data or identity path being tested.
Why C is Wrong: From Microsoft SQL Server Management Studio, set an email mask on the Email column.
is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It protects or manages a different security layer, so the required database access or protection behavior would still be incomplete.
Why D is Wrong: From Microsoft SQL Server Management Studio, grant the SELECT permission to the users for all the columns in the dbo.Customers table except Email. is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It is not the right enforcement point for this case; the scenario needs the control that governs the data or identity path being tested.

https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-checkdb-transact-sql?view=sql- server-ver15 Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
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 reduce the time it takes to perform database consistency checks of DB1.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.

Explanation:
To configure your user account as the Azure AD admin for the server named sql3700689S, you can use the Azure portal or the Azure CLI. Here are the steps for both methods:
Using the Azure portal:
Go to the Azure portal and select SQL Server - Azure Arc.
Select the server named sql3700689S and click on Active Directory admin.
Click on Set admin and choose your user account from the list of Azure AD users.
Click on Select and then Save to confirm the change.
You can verify the Azure AD admin by clicking on Active Directory admin again and checking the current admin.
Using the Azure CLI:
Install the Azure CLI and log in with your Azure account.
Run the following command to get the object ID of your user account: az ad user show --id < your-user-name
> --query objectId -o tsv
Run the following command to set your user account as the Azure AD admin for the server: az sql server ad- admin create --server sql3700689S --object-id < your-object-id > --display-name < your-user-name > You can verify the Azure AD admin by running the following command: az sql server ad-admin show -- server sql3700689S These are the steps to configure your user account as the Azure AD admin for the server named sql3700689S.
