Nokia 4A0-103 Exam - Topic 1 Question 119 Discussion

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

Question #: 119
Topic #: 1

Click on the exhibit.

A fully loose LSP MtoR6" 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. By default, which of the following about this LSP on an Alcatel-Lucent 7750 SR is FALSE?

AThe LSP will switch to R1-R3-R5-R6 after the resignal timer expires.

BThe old primary path and its detours are torn down after the new primary path is established.

CCSPF must be enabled to find a more optimal path.

DThe traffic is switched to R1-R3-R5-R6 in an MBB fashion.

B makes sense. Old paths get torn down after new ones.

No way A is false. It switches after the timer.

I feel like A could be misleading too. Resignal timer?

Agreed, C seems off. FRR handles it without CSPF.

I think option C is false. CSPF isn't needed for FRR.

CSPF isn't always needed, but it helps find better paths.

B is true, the old paths get torn down after the new one is set.

Wait, are you sure about that? Sounds off to me.

This question is really testing our understanding of FRR protection and LSP behavior. I better review those topics again.

Option C seems a bit odd. Why would CSPF need to be enabled for this scenario?

Haha, I bet the exam writers are trying to trick us with these tricky options. Time to put on my thinking cap!

I think option B is the correct answer, as the old primary path and its detours should be torn down after the new primary path is established.

I feel like MBB switching is a term we covered, but I’m not confident if it applies here with the traffic switching to R1-R3-R5-R6.

CSPF being required for a more optimal path seems familiar, but I can't recall if it's mandatory in this scenario.

I think option B sounds right because it makes sense that the old path would be torn down after establishing a new one.

I remember something about the resignal timer, but I'm not sure if it actually switches to R1-R3-R5-R6 after it expires.

This is a good opportunity to apply my knowledge of LSP behavior and Alcatel-Lucent routing protocols. I'll stay calm and work through this step-by-step.

I think I've got a handle on this. I'll methodically go through each answer choice and evaluate whether it's true or false based on the information provided.

I'm a bit confused by the options. I'll need to review my notes on CSPF and MBB to determine which one is false in this case.

A) is false, the LSP won't switch to R1-R3-R5-R6.

The question seems straightforward, but I'm not sure about the default behavior on the Alcatel-Lucent 7750 SR.

Okay, the key seems to be understanding how the LSP is rerouted after the link failure. I'll need to think through the default behavior of the Alcatel-Lucent 7750 SR in this scenario.

Hmm, this looks like a tricky one. I'll need to carefully read through the question and exhibit to understand the network topology and FRR protection details.
