Which of the following commands might you see associated with a router CLI, but not with a switch CLI?

• The show mac address-table command
• The show ip route command
• The show running-config command

Explanation: Cisco routers that do not also have any Layer 2 switch features support commands needed for Layer 3 routing as well as commands in common between Layer 2 switching and Layer 3 routing devices. In this case, the show interfaces status and show mac address-table commands happen to be commands supported on Layer 2 switches but not on routers. Both types of devices use the show running-config command. Of the answers, only the show ip interface brief command is unique to routers.
