You are the administrator of your company network. You are in charge of a SQL Server 2008 instance, each of which hosts a single database application. Now you want to perform a migration, move all the following four instances to a new SQL Server failover cluster which will hosts all four databases on a single virtual cluster IP address. The following table displays the configuration of the four instances:The four instances have been optimized and they have got no extra memory or free CPU cycles. Now you have to perform a configuration on the new cluster, so that it is able to undertake the workload of all the database applications while using as little hardware resources as possible. So 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
