Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 20

Which two statements apply to LLDP?

Answer options

• A. It runs on the data link layer
• B. It runs on the network layer
• C. It is not enabled by default on Cisco devices
• D. Enabled on Cisco devices by default

Correct answer: A, C

Explanation

The correct answers are A and C because LLDP (Link Layer Discovery Protocol) indeed operates at the data link layer (Layer 2) and is not enabled by default on Cisco devices. Options B and D are incorrect as LLDP does not function at the network layer and is not enabled by default.
