A SAN administrator needs to change the Domain ID and Core PID parameters on a switch that is part of a production fabric. Which two statements about this update are true? (Choose two.)

A. This process can be performed with the switch online without disruption.

B. The Core PID parameter does not need to be manually changed; it will automatically be selected.

C. The switch must be rebooted to set the Domain ID and Core PID.

D. This process cannot be performed with the switch online and is disruptive.
