Q1:

You need to find the broadcast address used on a LAN on your router. What command will you type into the router from user mode to find the broadcast address?

A show running-config

B show startup-config

C show interfaces

D show protocols

ANS:C - show interfaces

The command show ip protocols will actually show you the broadcast address for each interface - too bad it isn't a possible answer. Your best answer is show interfaces, which will provide the IP address and mask for each interface.
