A primary drawback to using shared storage clustering for high availability and disaster recover is:

A.
The creation of a single point of vulnerability.

B.
The increased network latency between the host computers and the RAID (Redundant Array of Independent Disk) subsystem.

C.
The asynchronous writes which must be used to flush the server cache.

D.
The highest storage capacity required by the RAID (Redundant Array of Independent Disks) subsystem.
