Which of the following refers to a location away from the computer center where document copies
and backup media are kept?

A.
Storage Area network

B.
Off-site storage

C.
On-site storage

D.
Network attached storage

Explanation:
Off-site storage refers to a location away from the computer center where documents
copies and backup media are kept. This storage method
is more secure but less convenient and more costly.
Answer option C is incorrect. Onsite storage refers to the same location where the work place is. It
is considered more convenient but less
secure in case of disaster.
Answer option A is incorrect. A storage area network (SAN) is an architecture to attach remote
computer storage devices (such as disk arrays,
tape libraries, and optical jukeboxes) to servers in such a way that the devices appear as locally
attached to the operating system.
Answer option D is incorrect. Network attached storage (NAS), in contrast to SAN, uses file-based
protocols such as NFS or SMB/CIFS where it
is clear that the storage is remote, and computers request a portion of an abstract file rather than a
disk block.
