Which of the following refers to a location away from the computer center where document copies
and backup media are kept?
A.
Off-site storage
B.
Network attached storage
C.
Storage Area network
D.
On-site 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 D 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 C 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 B 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.
