You have recently removed a SQL 2012 Database Engine instance from a computer running the
Windows Server 2008 R2 operating system. Prior to the removal of the instance, you had configured
affinity so that the default instance used CPU 0 and 1 and the second instance used CPU 2 and 3.

Which of the following commands would you use to accomplish this goal?

A.
ALTER SERVER CONFIGURATION SET PROCESS AFFINITY CPU = AUTO

B.
ALTER SERVER CONFIGURATION SET PROCESS AFFINITY CPU = 2,3

C.
ALTER SERVER CONFIGURATION SET PROCESS AFFINITY CPU = 0,1

D.
ALTER SERVER CONFIGURATION SET PROCESS AFFINITY CPU = 0,4
