Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 452

Which feature is used by LDP in the forwarding path within the MPLS cloud?

Answer options

• A. TDP
• B. TTL
• C. LSP
• D. IP forwarding

Correct answer: C

Explanation

The correct answer is C, LSP, as it stands for Label Switched Path, which is essential for LDP in managing the forwarding of packets through the MPLS cloud. Options A (TDP) and B (TTL) do not relate to LDP's role in the MPLS forwarding process, and option D (IP forwarding) is a different method of routing that does not involve MPLS.
