Administering a SQL Database Infrastructure — Question 233
You administer all the deployments of Microsoft SQL Server 2016 in your company.
You need to ensure that an OLTP database that uses a storage area network (SAN) remains available if any of the servers fail.
You also need to minimize the amount of storage used by the database.
Which configuration should you use?
Answer options
- A. Two servers configured in different data centers SQL Server Availability Group configured in Synchronous-Commit Availability Mode One server configured as an Active Secondary
- B. SQL Server that includes an application database configured to perform transactional replication
- C. Two servers configured in the same data center SQL Server Availability Group configured in AsynchronousCommit Availability Mode One server configured as an Active Secondary
- D. Two servers configured in different data centers SQL Server Availability Group configured in AsynchronousCommit Availability Mode
- E. Two servers configured in the same data center A primary server configured to perform log-shipping every 10 minutes A backup server configured as a warm standby
- F. Two servers configured on the same subnet SQL Server Availability Group configured in Synchronous-Commit Availability Mode
- G. SQL Server that includes an application database configured to perform snapshot replication
- H. Two servers configured in a Windows Failover Cluster in the same data center SQL Server configured as a clustered instance
Correct answer: H
Explanation
The correct answer is H because a Windows Failover Cluster provides high availability by allowing a secondary server to take over if the primary server fails, ensuring that the OLTP database remains accessible. Other options may not guarantee the same level of availability or may not minimize storage use effectively, such as asynchronous replication or log shipping which can lead to data latency or increased storage requirements.
