CISCO CCNA Exam – Q180

Which command would you configure globally on a Cisco router that would allow you to view directly connected Cisco devices?

A. enable cdp
B. cdp enable
C. cdp run
D. run cdp

Correct Answer: C

Explanation:
CDP is enabled on Cisco routers by default. If you prefer not to use the CDP capability, disable it with the no cdp run command. In order to re-enable CDP, use the cdp run command in global configuration mode. The “cdp enable” command is an interface command, not global.
