.Which Cisco IOS command is used to provide a description to an interface?

A. description

D. description interface number

Correct Answer: A

Explanation:
The description command is used to provide a description to an interface. It is not a mandatory configuration. However, if you have configured the description for an interface, anyone
who is working on the router can easily identify the purpose of the interface. Following is an example of the description command:
RouterA(config)# interface s0
RouterA(config-if)# description AT&T T1 to Internet
All the other options are syntactically incorrect.
