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?

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. Answer: Option A.

An engineer configured R6 as the headend LSR of an RSVP-TE LSP to router XR2, with the dynamic path signaled as R6-R2-R5-XR2. and set the OSPF cost of all links to 1. MPLS autotunnel backup Is enabled on all routers to protect the LSP. Which two NNHOP backup tunnels should the engineer use to complete the implementation? (Choose two.)
