Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 380

How is RSVP used with MPLS traffic engineering tunnels?

Answer options

• A. It assigns a tag to a packet as it travels through the tunnel.
• B. It removes and reassigns an MPLS label when the packet enters the tunnel.
• C. It reserves bandwidth along the path of the tunnel.
• D. It reduces the CPU burden when a packet travels through the tunnel.

Correct answer: C

Explanation

The correct answer is C because RSVP is responsible for reserving bandwidth along the specified path of the tunnel, ensuring that sufficient resources are available for data transmission. Options A, B, and D are incorrect as they do not accurately describe the function of RSVP in relation to MPLS traffic engineering tunnels.
