Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 93

What is true about CDP? (Choose two.)

Answer options

• A. disabled when native vlan mismatched
• B. can be disable on interface only
• C. send periodic broadcast
• D. send periodic multicast

Correct answer: A, D

Explanation

Option A is correct because CDP is indeed disabled when there is a native VLAN mismatch. Option D is also correct as CDP sends periodic multicast packets to discover neighboring devices. Options B and C are incorrect; CDP can be disabled globally or at the interface level, and it sends multicasts, not broadcasts.
