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.

CompTIA Network+ Question C-21

It has been determined by network operations that there is a severe bottleneck on the company’s mesh topology network. The field technician has chosen to use log management and found that one router is making routing decisions slower than others on the network. This is an example of which of the following?

A. Network device power issues
B. Network device CPU issues
C. Storage area network issues
D. Delayed responses from RADIUS

Correct Answer: B

Explanation:
Network processors (CPUs) are used in the manufacture of many different types of network equipment such as routers. Such a CPU on a router could become bottleneck for the network traffic. The routing through that device would then slow down.
