Refer to the exhibit.

The customer network has blue and red VSANs redundantly connected. Path A having a 4-ISL
port channel and Path B having a 2-ISL port channel. Changes to the physical topology are not
allowed for the next six months. All the traffic now flows over Path A with congestion occurring on
both VSANs at peak times. The blue VSAN is, on the average, generating four times the amount
of data than that of the red VSAN. How can the blue and red VSAN traffic be separated over the
two paths, while preserving redundancy?

Exhibit:

A.
In the blue VSAN, give Path Aa lower FSPF cost than Path B, in the red VSAN, give
Path B a lower FSPF cost than Path A.

B.
In the blue VSAN, give Path B a lower FSPF cost than Path A, in the red VSAN, give
Path A a lower FSPF cost than Path B.

C.
Make a zone in the blue VSAN with only ISL ports on Path A, and make another zone in the red
VSAN with only ISL ports on Path B.

D.
Make a zone in the blue VSAN with only ISL ports on Path B, and make another zone in the red
VSAN with only ISL ports on Path A.

Explanation:

FSPF cost helps determine the FC route. Lower = better.
By giving VSAN blue a lower cost on Path A, it will take that path if available, likewise with Red/B.
