NEW QUESTION # 147
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have two Azure SQL Database servers named Server1 and Server2. Each server contains an Azure SQL database named Database1.
You need to restore Database1 from Server1 to Server2. The solution must replace the existing Database1 on Server2.
Solution: You restore Database1 from Server1 to the Server2 by using the RESTORE Transact-SQL command and the REPLACE option.
Does this meet the goal?
Answer: B
Explanation:
The REPLACE option overrides several important safety checks that restore normally performs. The overridden checks are as follows:
Restoring over an existing database with a backup taken of another database.
With the REPLACE option, restore allows you to overwrite an existing database with whatever database is in the backup set, even if the specified database name differs from the database name recorded in the backup set.
This can result in accidentally overwriting a database by a different database.
Reference:
https://docs.microsoft.com/en-us/sql/t-sql/statements/restore-statements-transact-sql Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why A is Correct: Yes is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. In this scenario, the important constraint is: Each question in the series contains a unique solution that might meet the stated goals. Yes satisfies that constraint without adding an unrelated service or manual process.
Why B is Wrong: No 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.

Hotspot Question
You have an Azure SQL database.
You need to identify whether a delayed query execution is associated to a RESOURCE_SEMAPHORE wait.
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: wait_type
Determine if a RESOURCE_SEMAHPORE wait is a top wait
Use the following query to determine if a RESOURCE_SEMAHPORE wait is a top wait SELECT wait_type, SUM(wait_time) AS total_wait_time_ms FROM sys.dm_exec_requests AS req JOIN sys.dm_exec_sessions AS sess ON req.session_id = sess.session_id WHERE is_user_process = 1 GROUP BY wait_type ORDER BY SUM(wait_time) DESC; Box 2: sys.dm_exec_requests Use the sys.dm_exec_requests or sys.dm_os_waiting_tasks to see the wait_type and wait_time.
Azure SQL RESOURCE_SEMAPHORE wait "wait_time" is_user_process
NEW QUESTION # 150
You have an instance of SQL Server on Azure Virtual Machines named VM1.
You need to implement a disaster recovery solution that meets the following requirements:
- Returns the solution to an operational state within 15 minutes of a
failure
- Can perform disaster recovery testing in an isolated environment
- Minimizes administrative effort
What should you include in the solution?
Answer: A
Explanation:
Replication with Azure Site Recover:
- RTO is typically less than 15 minutes.
- RPO: One hour for application consistency and five minutes for crash consistency.
Always On availability group RPO: Because replication to the secondary replica is asynchronous, there's some data loss.
