Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 244

Which function does RSVP perform in a Cisco MPLS TE environment?

Answer options

• A. It establishes targeted LDP sessions between neighbors that are directly connected.
• B. It signals to LDP protocol along the path that a Cisco MPLS TE will be configured.
• C. It reserves bandwidth for LDP sessions between routers participating in a Cisco MPLS TE.
• D. It reserves the bandwidth along the path between the head-end and tail-end router.

Correct answer: D

Explanation

The correct answer is D because RSVP is responsible for reserving bandwidth along the path from the head-end to the tail-end router in an MPLS TE environment. Options A, B, and C are incorrect as they pertain to LDP sessions and do not accurately describe RSVP's function in bandwidth reservation.
