A SQL server needs several terabytes of disk space available to do an uncompressed backup of a database.

A.
iSCSI SAN
B.
FCoE SAN
C.
NAS
D.
USB flash drive
Explanation:
A NAS is a Network Attached Storage device; typically a bunch of cheap hard disks, usually arranged in a Raid
A NAS is essentially a file server that connects to an Ethernet network and is configured with a TCP/IP address.
A NAS supports Windows networking and works at the file level as opposed to a SAN (Storage Area Network)
which works at the block level when dealing with data. You can access file shares on a NAS in the same way
A NAS is a much cheaper option than a SAN.
