Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 424

What is the downstream unsolicited distribution method in MPLS?

Answer options

• A. It advertises labels to peers only when the peer requests.
• B. It sends a unicast hello message to a specific LSR.
• C. It sends a unicast hello message to a specific LER.
• D. It advertises labels to peers without peer request.

Correct answer: D

Explanation

The correct answer is D because the downstream unsolicited distribution method in MPLS involves advertising labels to peers regardless of whether a request has been made. Options A, B, and C are incorrect as they describe methods that either require a request or pertain to hello messages, which are not relevant to the label advertisement process.
