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.
