Nokia 4A0-103 Exam - Topic 3 Question 109 Discussion

Actual exam question for Nokia's 4A0-103 exam

Question #: 109
Topic #: 3

Click on the exhibit.

A fully loose LSP "toR6" is enabled with FRR protection. All links have the same cost. After the link between R2 and R4 goes down, FRR protection repairs the LSP and traffic traverses on R1-R2-R7-R8-R4-R6. Which of the following about this CSPF-enabled LSP on an Alcatel-Lucent 7750 SR is TRUE?

AThe LSP will stay on the current path indefinitely unless another failure occurs.

BThe LSP will stay on the current path until the resignal timer expires.

CThe LSP will switchover to R1-R2-R3-R5-R6 after the resignal timer expires.

DThe LSP will switchover to R1-R3-R5-R6 after the retry timer expires.

No way, it's definitely not going to R1-R3-R5-R6!

Wait, is it really going to stay there indefinitely?

I think it might switch to R1-R2-R3-R5-R6 after the timer.

I recall that FRR is supposed to quickly reroute traffic, but I can't remember if it stays on the new path indefinitely or if it eventually checks for a better route.

I’m a bit confused about the difference between the resignal timer and the retry timer. I feel like I might mix them up during the exam.

This question seems similar to one we practiced where we discussed LSP paths and timers. I think the LSP might stay on the current path until the resignal timer expires.

I remember studying about LSPs and FRR, but I'm not entirely sure how the resignal timer works in this scenario.

Okay, I think I've got it. The LSP will stay on the current path indefinitely after the FRR protection kicks in, unless another failure occurs or the resignal timer expires, which could trigger a switchover to a different path. Option B seems to be the correct answer.

Based on the details provided, I'm leaning towards option B. The LSP should stay on the current path until the resignal timer expires, at which point it may switch to a different path. But I'll double-check my reasoning.

I'm a bit confused by the different timer options mentioned. I'll need to review my MPLS knowledge to understand the difference between the resignal and retry timers and how they impact the LSP behavior.

Okay, the key information seems to be that the LSP is using FRR protection and all links have the same cost. I think the answer has to do with how the LSP reacts after the link failure is repaired.

Hmm, this looks like a tricky MPLS question. I'll need to carefully read through the details and think through the FRR protection and resignal timer behavior.

Option C looks promising, but I'm not convinced. Wouldn't the LSP just try to find the shortest path after the resignal timer expires? I'm going to have to think this one through a bit more.

Let's review the options again to make sure we understand the behavior correctly.

I agree, but I'm not sure if it will switch over to another path after that.

Haha, the question is talking about an Alcatel-Lucent 7750 SR, which sounds like a fancy piece of networking gear. I wonder if they have a 'Shake and Bake' version for the rest of us.

I'm not sure about this one. The question mentions FRR protection, so I'm guessing the LSP won't switch to a new path unless another failure occurs.

Option B seems like the correct answer. The LSP will stay on the current path until the resignal timer expires, after which it will re-optimize and find a new path.
