Refer to the exhibit. Port Fa0/2 has already been configured appropriately. The IP
phone and PC work properly. Which switch configuration would be most appropriate for
port Fa0/2 if the network administrator has the following goals?
No one is allowed to disconnect the IP phone or the PC and connect some other wired
device. If a different device is connected, port Fa0/2 is shut down.
The switch should automatically detect the MAC address of the IP phone and the PC
and add those addresses to the running configuration.
