CompTIA Security+ Question G-44

Which of the following can be used to maintain a higher level of security in a SAN by allowing isolation of mis-configurations or faults?

A. VLAN
B. Protocol security
C. Port security
D. VSAN

Answer: D

Explanation:
A storage area network (SAN) is a secondary network that offers storage isolation by consolidating storage devices such as hard drives, drive arrays, optical jukeboxes, and tape libraries. Virtualization can be used to further enhance the security of a SAN by using switches to create a VSAN. These switches act as routers controlling and filtering traffic into and out of the VSAN while allowing unrestricted traffic within the VSAN.
