Nokia Exam 4A0-100 Topic 7 Question 95 Discussion

Actual exam question for Nokia's 4A0-100 exam

Question #: 95
Topic #: 7

Which of the following are correct statements about MPLS labels (Choose three.)?

AA series of labels from one LER to another LER represent a logical tunnel known as an LSP.

BLabels used for a LSP may be static but are usually signaled dynamically with an MPLS label signaling protocol.

CLabels are locally significant to the MPLS router which means its possible for two routers on the LSP path to use the same label.

DLabels are globally significant to the MPLS network which means all labels on the LSP path must be unique.

ELabels used for an LSP must be statically assigned by the service provider.

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.

Yes, C and D are also correct, labels are locally significant and must be unique across the network.

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.

Labels need to be unique to avoid confusion in the network. It's important for smooth traffic flow.

I agree, B, C, and D are the correct statements. MPLS labels are like secret codes for routers.

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.

Actually, D is also correct. Labels must be unique across the MPLS network.

I think A, B, and C are correct. Labels represent a logical tunnel between LERs.

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!
