What action must be taken to make fc1/1 capable of being an ISL port channel member operating at 4 GB?

A.
One of the interfaces between fc1/2 and fc1/6 must be placed in out-of-service mode to free up
bandwidth in the port group so that fc1/1 can use that bandwidth.

B.
Interface fc1/1 must be placed into dedicated rate mode.

C.
The B2B credit value of interface fc1/1 must be raised to a minimum of 100.

D.
No action is necessary because shared rate mode ports are fine for ISLs.

E.
No action is possible because module 1 is oversubscribed and will only support ISLs if the ports
operate at 2GBs.
