Answer: A
NEW QUESTION # 402
You are designing a dimension table in an Azure Synapse Analytics dedicated SQL pool.
You need to create a surrogate key for the table. The solution must provide the fastest query performance.
What should you use for the surrogate key?
Answer: C
Explanation:
Dedicated SQL pool supports many, but not all, of the table features offered by other databases.
Surrogate keys are not supported. Implement it with an Identity column.

NEW QUESTION # 403
Hotspot Question
You have an Azure SQL database named db1 that contains an Azure Active Directory (Azure AD) user named user1.
You need to test impersonation of user1 in db1 by running a SELECT statement and returning to the original execution context.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: USER
Using EXECUTE AS and REVERT to switch context.
The following example creates a context execution stack using multiple principals. The REVERT statement is then used to reset the execution context to the previous caller.
**
EXECUTE AS USER = 'user2';
--The following REVERT statements will reset the execution context to the previous context.
REVERT;
**
Box 2: REVERT

NEW QUESTION # 404
You have an Azure subscription that uses a domain named contoso.com.
You have two Azure VMs named DBServer1 and DBServer2. Each of them hosts a default SQL Server instance. DBServer1 is in the East US Azure region and contains a database named DatabaseA. DBServer2 is in the West US Azure region.
DBServer1 has a high volume of data changes and low latency requirements for data writes.
You need to configure a new availability group for DatabaseA. The secondary replica will reside on DBServer2.
What should you do?
Answer: C
Explanation:
Reference:
https://docs.microsoft.com/en-us/sql/database-engine/availability-groups/windows/availability-modes-always- on-availability-groups?view=sql-server-ver15 Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why C is Correct: Configure the primary endpoint as TCP://DBServer1.contoso.com:5022, configure the secondary endpoint as TCP://DBServer2.contoso.com:5022, and set the availability mode to Asynchronous. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. This fits the case because the requested outcome is: DBServer1 has a high volume of data changes and low latency requirements for data writes. The selected feature addresses that outcome directly rather than relying on a workaround.
Why A is Wrong: Configure the primary endpoint as TCP://DBServer1.contoso.com:445, configure the secondary endpoint as TCP://DBServer2.contoso.com:445, and set the availability mode to Asynchronous. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
Why B is Wrong: Configure the primary endpoint as TCP://DBServer1.contoso.com:445, configure the secondary endpoint as TCP://DBServer2.contoso.com:445, and set the availability mode to Synchronous. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
Why D is Wrong: Configure the primary endpoint as TCP://DBServer1.contoso.com:5022, configure the secondary endpoint as TCP://DBServer2.contoso.com:5022, and set the availability mode to Synchronous. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
