B) Apply any unapplied transaction log backups in sequence to each secondary database by using the WITH RECOVERY option on the last log.
C) Copy all log shipping network shares to the secondary instance.
D) Back up the tail of the transaction log of primary databases by using the WITH NORECOVERY option.
E) Redirect client computers to the secondary instance.

2. You are a professional level SQL Sever 2008 Database Administrator.

the instances.
All four databases will be hosted by the new cluster on a single virtual cluster IP address.
Since you are the technical support, you are required to set the new cluster to handle the workload of all the database applications with the least amount of hardware resources.
From the four cluster configuration, which one should be utilized?

A) Two-node active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
B) Four-node active/active/active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
