Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 240

Which benefit is provided by FRR?

Answer options

• A. It provides fast forwarding path failure detection times for all media.
• B. It provides rapid failure detection between forwarding engines.
• C. It provides performance data for the service provider network.
• D. It protects Cisco MPLS TE LSPs from link and node failures.

Correct answer: D

Explanation

The correct answer is D because FRR (Fast Reroute) is specifically designed to protect MPLS Traffic Engineering Label Switched Paths (TE LSPs) from failures in links and nodes, ensuring continuous service. Options A and B describe detection capabilities, which are not the primary function of FRR, while option C refers to performance data, which is unrelated to FRR's main purpose.
