Nokia Exam 4A0-116 Topic 12 Question 32 Discussion

Actual exam question for Nokia's 4A0-116 exam
Question #: 32
Topic #: 12
[All 4A0-116 Questions]

The exhibit presents packets being transmitted inside an LSP's multi-segment primary path going from router R1 to router R8. The LSP also has a standby secondary path, and Seamless-BFD has been enabled on the primary path. The link between routers R1 and R2 fails, and fast re-route (FRR) is triggered. As a result, router R1 forwards the packets to router R3 and adds the proper FRR encapsulation to reach which router?

This question is about as straightforward as a labyrinth. But I'll go with C and hope for the best.

I agree, C makes sense because it is the tail-end of the active segment.

But the question mentions fast re-route (FRR) being triggered, so it makes sense to reach the tail-end of the LSP, which is router R8.

I've got to go with C. It just makes the most sense that the packets would be forwarded to the tail-end of the active segment.

Hmm, this is a tricky one. I'm leaning towards D though. Reaching the tail-end of the LSP, which is R8, seems like the intended result of the FRR process.

B sounds more logical to me. Going back to the original path through R5 seems like the shortest way to get to the destination.

I think the answer is C. R4 is the tail-end of the active segment, so that's where the packets need to be forwarded after the link failure.
