You administer four SQL Server 2008 instances. Each instance hosts a single database
application. You plan to migrate all four instances to a new SQL Server failover cluster. The
four instances are configured as shown in the following table. The four instances are fully
optimized and have no spare CPU cycles or extra memory. The new cluster will host all four
databases on a single virtual cluster IP address. You need to ensure that the new cluster is
configured to handle the workload of all the database applications by using the minimum
amount of hardware resources. Which cluster configuration should you use?
A.
Two-node active/active cluster that has each node containing a minimum of 9 processors
and a 25-GB memory
B.
Two-node active/passive cluster that has each node containing a minimum of 18
processors and a 50-GB memory
C.
Four-node active/active/active/active cluster that has each node containing a minimum of
9 processors and a 25-GB memory
D.
Four-node active/active/active/passive cluster that has each node containing a minimum
of 18 processors and a 50-GB memory
