You administer all the deployments of Microsoft SQLServer 2012 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?
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 Asynchronous-Commit Availability
Mode
� One server configured as an Active Secondary
D.
� Two servers configured in different data centers
� SQL Server Availability Group configured in Asynchronous-Commit 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
Explanation:
I’ll stick with “H” as that seems the logical choice.
A failover cluster ensures database availability in the event that one server fails.
By using instance clustering, one can substantially reduce space usage as replicas of the database logs do not need to be stored on the SAN.
