NEW QUESTION # 46
You have a Microsoft SQL Server 2019 instance in an on-premises datacenter. The instance contains a 4-TB database named DB1.
You plan to migrate DB1 to an Azure SQL Database managed instance.
What should you use to minimize downtime and data loss during the migration?
- A. database mirroring
- B. distributed availability groups
- C. log shipping
- D. Database Migration Assistant
Answer: B
Explanation:
The Data Migration Assistant (DMA) helps you upgrade to a modern data platform by detecting compatibility issues that can impact database functionality in your new version of SQL Server or Azure SQL Database. DMA recommends performance and reliability improvements for your target environment and allows you to move your schema, data, and uncontained objects from your source server to your target server.
Note: SQL Managed Instance supports the following database migration options (currently these are the only supported migration methods):
* Azure Database Migration Service - migration with near-zero downtime.
* Native RESTORE DATABASE FROM URL - uses native backups from SQL Server and requires some downtime.

NEW QUESTION # 48
DRAG DROP
You have a new Azure SQL database named DB1 on an Azure SQL server named AzSQL1.
The only user who was created is the server administrator.
You need to create a contained database user in DB1 who will use Azure Active Directory (Azure AD) for
authentication.
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.
Select and Place:
Answer:
Explanation:
Section: [none]
Explanation:
Step 1: Set up the Active Directory Admin for AzSQL1.
Step 2: Connect to DB1 by using the server administrator.
Sign into your managed instance with an Azure AD login granted with the sysadmin role.
Step 3: Create a user by using the FROM EXTERNAL PROVIDER clause.
FROM EXTERNAL PROVIDER is available for creating server-level Azure AD logins in SQL Database
managed instance. Azure AD logins allow database-level Azure AD principals to be mapped to server-level
Azure AD logins. To create an Azure AD user from an Azure AD login use the following syntax:
CREATE USER [AAD_principal] FROM LOGIN [Azure AD login]

Which resource provider should you enable?
- A. Microsoft.EventGrid
- B. Microsoft.Sql
- C. Microsoft.EventHub

NEW QUESTION # 60
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. Query Performance Insight in the Azure portal
- B. Query Store in Microsoft SQL Server Management Studio (SSMS)
- C. Extended Events in Microsoft SQL Server Management Studio (SSMS)
- D. Performance Recommendations in the Azure portal
Answer: B
Explanation:
Section: [none]
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.
