Which statement about Cisco Discovery Protocol configuration on a Cisco switch is true?

A. CDP is enabled by default and can be disabled globally with the command no cdp run.

B. CDP is disabled by default and can be enabled globally with the command cdp enable.

C. CDP is enabled by default and can be disabled globally with the command no cdp enable.

D. CDP is disabled by default and can be enabled globally with the command cdp run.








 

Suggested Answer: A

CDP is enabled on your router by default, which means the Cisco IOS software will receive CDP information. CDP also is enabled on supported interfaces by default. To disable CDP on an interface, use the "no cdp enable interface" configuration command. To disable it globally, use the "no cdp run" command.
