.Which Cisco IOS command disables Cisco Discovery Protocol Version 2 (CDPv2) advertisements?

A. no cdp advertise-v2
B. no cdp v2-advertise
C. no cdp run
D. no cdp enable

Correct Answer: A

Explanation:
The no cdp advertise-v2 command disables CDPv2 advertisements. It is the reverse of the cdp advertise-v2 command, which enables CDPv2 advertisements on a device.
The no cdp v2-advertise command is not a valid Cisco IOS command.
The no cdp run command disables CDP, not CDPv2 advertisements.
The no cdp enable command disables CDP on an interface.
