Identify three protocols found in the control plane. (Choose three.)

Question

Group of answer choices

CDP

SSH

LLDP

OSFP

Answer 1

The three protocols found in the control plane from the options provided are:

1. CDP (Cisco Discovery Protocol) - ACisco proprietary protocol used for network device discovery and information exchange on a local area network.

2. LLDP (Link Layer Discovery Protocol) - A vendor-neutral protocol used for network device discovery; it facilitates the identification of neighboring devices and their capabilities.

3. OSPF (Open Shortest Path First) - A widely used routing protocol in IP networks that helps routers find the best path for forwarding packets.

SSH (Secure Shell) is primarily an application layer protocol used for secure remote administration and is not a control plane protocol.

So the correct answers are: CDP, LLDP, OSPF.
