Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 18

You are testing the capabilities of MPLS OAM ping. Which statement is true?

Answer options

• A. An LSP is not required for the reply to reach the ingress MPLS router.
• B. An LSP breakage results in the ingress MPLS router never receiving any reply.
• C. MPLS OAM ping works solely with P2P LSPs.
• D. MPLS OAM ping works solely with Cisco MPLS TE.

Correct answer: A

Explanation

The correct answer is A because the reply can reach the ingress MPLS router without an LSP being necessary. Option B is incorrect as LSP breakage would prevent replies, while C and D inaccurately limit MPLS OAM ping to specific types of LSPs or vendor implementations.
