Nokia 4A0-116 Exam - Topic 3 Question 61 Discussion

Actual exam question for Nokia's 4A0-116 exam
Question #: 61
Topic #: 3
[All 4A0-116 Questions]

Which of the following statements about Multi-Protocol Label Switching networks is FALSE?

Show Suggested Answer Hide Answer
Suggested Answer: D

The data is transparently carried from end to end: This statement is not true, MPLS does not provide data transparency, which means that the data is not carried unmodified from end to end. MPLS uses labels to forward data, so the original IP packets are encapsulated in new MPLS packets, and the original IP headers are not visible at the egress LSR.

MPLS does use a signaling protocol for labels.

Wait, so MPLS isn't just a fancy way to say "Multi-Tasking Ping Latency Simulator"? My bad.

I'm pretty sure the MPLS labels are used to forward data, not to exchange them. Option A must be false.

This exam question is a real head-scratcher. I hope the answers aren't as confusing as the question!

Option D is the correct answer. MPLS networks do not transparently carry data from end to end.

Option C is incorrect. An LSP is a unidirectional path, not a bi-directional tunnel.

I’m a bit confused about the last option. I think data being transparently carried might be true, but I’m not entirely sure how that fits with MPLS.

The term "bi-directional tunnel" sounds familiar, but I can't recall if that's exactly how LSPs work in MPLS.

I feel like I've seen a question about LSRs forwarding data based on MPLS labels before, so I think that one is true.

I think I remember that MPLS uses a signaling protocol, but I'm not sure if it's specifically for exchanging labels.

I remember learning about MPLS in class, but I'm drawing a blank on the details right now. I'll have to review my notes before answering this.

The data being transparently carried from end to end sounds right to me. I'm leaning towards D being the false statement.

Okay, I'm pretty confident on this. B and D are definitely true, but I'm not sure about C. I'll have to double-check that one.

Hmm, I'm a bit confused on the difference between an LSR and an LSP. I'll have to think through that one.

I think I know this one. MPLS uses a signaling protocol like LDP or RSVP-TE to exchange labels, so A is true.
