I'm leaning towards option A, feels right to me!

Arminda 11 months ago

All links having the same cost complicates things a bit.

Barney 11 months ago

Wait, R3 isn't even in the path, how can it be a PLR?

Charlena 11 months ago

I think R2, R4, and R6 being MPs makes sense.

Melynda 12 months ago

R1, R2, and R4 can definitely be PLRs.

Maynard 12 months ago

I’m leaning towards option B, but I’m not confident. I remember something about MPs needing to be at the end of the path.

Arlene 1 year ago

I feel like I read that all nodes in the path can be PLRs, but I’m confused about the specifics of which ones can be MPs.

Nobuko 1 year ago

I think I practiced a similar question where R1 and R2 were definitely PLRs, but I can't recall if R6 was the MP or not.

Teri 1 year ago

I remember that PLRs are the nodes that can reroute traffic, but I'm not entirely sure which ones can be classified as MPs in this scenario.

Marti 1 year ago

This is a good example of a question that requires a solid grasp of MPLS fast reroute mechanics. I'll make sure to review those concepts thoroughly before the exam to be prepared for similar questions.

Wilda 1 year ago

Alright, I think I've got it. Based on the information provided, the correct answer is option B. R1, R2, and R4 can be PLRs, while R2, R4, and R6 are the MPs. I'll mark that down and move on to the next question.

Polly 1 year ago

I'm a bit confused by the options here. I'll need to double-check my understanding of PLRs and MPs in an MPLS network with fast reroute. Let me review the key concepts before selecting an answer.

Ivette 1 year ago

Okay, let me think this through step-by-step. The LSP traverses R1-R2-R4-R6, and fast reroute with link protection is enabled. I'll need to consider which routers can act as PLRs and which one is the MP.

Raina 1 year ago

Hmm, this looks like a tricky MPLS question. I'll need to carefully analyze the network topology and the information provided to determine the correct PLRs and MPs.

Gretchen 1 year ago

This question seems straightforward, I'm pretty confident I can get it right.

Truman 1 year ago

I'm not entirely sure about this one. The wording is a bit tricky, and I want to make sure I understand the concepts correctly before answering.

Julene 1 year ago

This seems like a straightforward question about the characteristics of a robust design. I'll carefully read through the options and think about which one best fits the definition.

Blondell 1 year ago

Hmm, I'm a little fuzzy on the exact definitions of those terms. Let me think this through carefully.

I've been studying this material for weeks, and I still can't decide. Maybe I should just eenie-meenie-miney-mo it!

C) R1, R2, R3, R4, and R5 can be PLRs; R6 is the MP.

Tuyet 1 year ago

Hmm, this is a tricky one. I'm leaning towards Option C, but I might need to stare at the diagram a bit longer to be sure.

Celestine 1 year ago

↳ replying to Tuyet

I'm not sure, but I think Option B could also be a possibility. R1, R2, and R4 as PLRs; R2, R4, and R6 as MPs.

Mitzie 1 year ago

↳ replying to Tuyet

I agree with you, Option A seems to be the most logical choice.

Sylvie 1 year ago

↳ replying to Tuyet

I think Option A is correct. R1, R2, and R4 can be PLRs; R6 is the MP.

Cheryl 1 year ago

Haha, this question is a classic brain-teaser! I'm going with Option D just to see if the graders have a sense of humor.

Timothy 1 year ago

↳ replying to Cheryl

Let's go with Option C for a different approach.

Noah 1 year ago

↳ replying to Cheryl

I'm leaning towards Option B, covering all bases.

Julieta 1 year ago

↳ replying to Cheryl

I think Option A is the safer bet here.

Lenna 1 year ago

↳ replying to Cheryl

Option D seems like a risky choice, but it could be right.

Dannette 2 years ago

I'm pretty sure Option A is right. R1, R2, and R4 can be PLRs, and R6 is the MP.

Shannan 2 years ago

But if all links have the same cost, wouldn't it make more sense for R1, R2, and R4 to be PLRs?

Zack 2 years ago

Option B is the correct answer. R1, R2, and R4 can be PLRs, while R2, R4, and R6 are the MPs.

Pa 1 year ago

↳ replying to Zack

Thanks for clarifying!

Marshall 1 year ago

↳ replying to Zack

That makes sense.

Barbra 1 year ago

↳ replying to Zack

That makes sense. The PLRs are responsible for protecting the LSP, while the MPs are the merge points.

Beckie 1 year ago

↳ replying to Zack

R1, R2, and R4 can be PLRs; R2, R4, and R6 are MPs.

Shayne 1 year ago

I think the correct answer is B) R1, R2, and R4 can be PLRs; R2, R4, and R6 are MPs.

I disagree, I believe the answer is B) R1, R2, and R4 can be PLRs; R2, R4, and R6 are MPs.

Shannan 2 years ago

I think the answer is A) R1, R2, and R4 can be PLRs; R6 is the MP.
