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

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 reenable CDP, use the cdp run command in global
configuration mode. The “cdp enable” command is an interface command, not global.
