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 spearted over the two paths, while preserving redundancy?

A.
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.

B.
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.

C.
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.

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