Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 140

An engineer is implementing a Cisco MPLS TE tunnel to improve the streaming experience for the clients of a video-on-demand server. Which action must the engineer perform to configure extended discovery to support the MPLS LDP session between the headend and tailend routers?

Answer options

• A. Configure a targeted neighbor session.
• B. Configure an access list on the interface to permit TCP and UDP traffic.
• C. Configure a Cisco MPLS TE tunnel on both ends of the session.
• D. Configure the interface bandwidth to handle TCP and UDP traffic between the LDP peers.

Correct answer: A

Explanation

The correct answer is A because configuring a targeted neighbor session is essential for establishing MPLS LDP communication between routers in an MPLS TE setup. The other options, while relevant to network setup, do not specifically address the requirement for extended discovery necessary for the LDP session.
