Which element is the most critical in a SAN design that must need NSPOF goals?

A.
MultipleFibre Channel switches

B.
Enterprise class Directorswitches

C.
Two or more redundant fabrics

D.
Quad portfibre channel adapters

Explanation:
Level 4: multiple fabrics and device paths (NSPOF).
Using two fabrics may increase implementation costs, but it also increases the total number
of available ports.
For example, in a single meshed fabric with four switches, you have a maximum of 52 user
ports for servers and storage. Implementing the same topology using two fabrics increases
the maximum number of user ports to 104.
