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.
