JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2024) — Question 53

You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically negotiate the power requirements for the new connection with the EX Series switches.
In this scenario, which protocol should be used to enable this behavior?

Answer options

Correct answer: C

Explanation

The correct answer is LLDP-MED, which is specifically designed for IP phones to negotiate power requirements automatically with network switches. CDP is a Cisco proprietary protocol and does not fully support LLDP-MED features, while MP-BGP is unrelated to power negotiation and LLDP, though useful for network discovery, does not provide the specific power negotiation capabilities needed in this scenario.
