Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 304

Which fact must a network engineer consider when planning to deploy RSVP-TE FRR?

Answer options

• A. PLR prefers FRR NHOP backup tunnels over NNHOP tunnels
• B. FRR protects MPLS LDP and RSVP-TE LSPs
• C. The FRR backup tunnel reserves the total bandwidth of all protected tunnels
• D. PLR prefers FRR NNHOP backup tunnels over NHOP tunnels

Correct answer: D

Explanation

The correct answer is D because the Primary LSR (PLR) prioritizes NNHOP backup tunnels for their efficiency. Options A and C are incorrect as they misrepresent the preferences and bandwidth reservation of FRR. Option B does not address the specific consideration about PLR preferences in backup tunnel selection.
