Nokia 4A0-100 Exam - Topic 7 Question 95 Discussion

Which of the following are correct statements about MPLS labels (Choose three.)?
D) Labels are globally significant to the MPLS network which means all labels on the LSP path must be unique.
A) A series of labels from one LER to another LER represent a logical tunnel known as an LSP.
B) Labels used for a LSP may be static but are usually signaled dynamically with an MPLS label signaling protocol.
C) Labels are locally significant to the MPLS router which means its possible for two routers on the LSP path to use the same label.
E) Labels used for an LSP must be statically assigned by the service provider.

I thought labels had to be unique across the whole network, not just locally!

Wait, are labels really globally significant? That sounds off.

I agree, labels are locally significant, so they can repeat on different routers.

A series of labels from one LER to another LER is definitely an LSP.

D seems wrong to me because I remember that labels are not globally significant; they can be reused by different routers on the same path.

I recall that labels are locally significant, which makes C seem correct. I think we discussed how different routers can use the same label without conflict.

I’m a bit unsure about the static vs dynamic labeling. I think B sounds right because we talked about signaling protocols in class, but I’m not completely confident.

I remember that LSP stands for Label Switched Path, and it definitely involves labels from one LER to another, so I think A is correct.

Okay, I remember learning about MPLS labels in class. I think the key is understanding the difference between locally significant and globally significant labels. That should help me identify the correct statements.

Hmm, I'm a bit unsure about this one. The question is asking about specific details of MPLS labels that I'm not totally confident about. I'll have to think it through carefully.

This question seems straightforward, I think I can handle it. Let me carefully read through the options and think about what I know about MPLS labels.

Ah, this is a good one. MPLS labels are an important networking concept, so I'm glad to see a question on it. I'll use my knowledge of MPLS tunnels and signaling protocols to work through the options.

I'm a bit confused on this one. I'll need to review my notes to refresh my memory on the best practices for these ITSI functions.

Ugh, MPLS labels, really? Okay, let's think this through... B is right, labels are usually signaled dynamically. C and D are also correct, labels are locally significant and must be unique across the network. I'm pretty sure A and E are wrong, but I'm not 100% sure. Time to make an educated guess and move on to the next question.

Hah, easy peasy! B, C, and D are the correct ones. I always remember that MPLS labels are like secret codes that routers use to keep track of the traffic, and they have to be unique so the network doesn't get confused. Now, where's the coffee? I need a caffeine boost for the rest of this exam.

Hmm, let's see... A, B, and C. Wait, no, D too. Labels must be unique across the MPLS network, not locally significant. I guess my MPLS knowledge is a bit rusty, time to hit the books again.

B, C, and D are correct. Labels are usually signaled dynamically, can be reused on different routers, and must be unique across the MPLS network. I'm glad they didn't ask about MPLS traffic engineering, that's a whole other can of worms!
