You administer all the deployments of Microsoft SQL Server 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
Anyone opting for option F?

I agree, F for me

the OLTP systems don’t allow loose of a transaction.
FO clusters use shared storage, Always-ON use separate storage.

minimize the amount of storage, so failover clustering is the only one that brings redundancy when a server fails

I would stick with H. Failover Clusters are commonly configured to share storage therefore best meeting the requirements.

yeah minimize the amount of storage is key. availability groups double the space needed for the database. Also mentioning a SAN means clustering for sql is available.

Failover for redundancy. H.

In my opinion H) Failover Clustering would be the best choice over Availability Groups as it uses Shared storage to minimize storage requirements.

Answer H for the following 2 Reasons :
==> The distribution uses a SAN Storage so basically we’ll have two servers IN
THE SAME SUBNET sharing the same storage
==> it uses Shared storage to minimize storage requirements: If we choose
AlwaysOn Availability group we’ll have 2 replicas PRIMARY / SECONDARY
Replica, and in which one of them the database we’ll be replicated more than
2 times which consequently WILL USE A LOT OF DISK SPACE. So AlwausOn
availability group is to cross
