Nokia Exam 4A0-116 Topic 1 Question 52 Discussion

Actual exam question for Nokia's 4A0-116 exam
Question #: 52
Topic #: 1
[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.

I think the false statement is A, MPLS does not use a signaling protocol for label exchange.

I believe the false statement is C, LSPs are not bi-directional tunnels.

I agree with Cathrine, data is not transparently carried in MPLS networks.

This question is a piece of cake! Roselleryone knows that option C is the false statement. Who doesn't love a good uni-directional tunnel?

Hmm, I'm pretty sure B is the correct answer. MPLS routers, or LSRs, forward data based on the MPLS labels, not the IP headers.

User 2: Yeah, that's correct. The labels are used to determine the path the data takes through the network.

Option A is the way to go. MPLS uses a signaling protocol like LDP or RSVP-TE to exchange labels between routers.

D seems like the false statement to me. MPLS networks provide transparency for the data, but not from end to end.

I think option C is the correct answer. An LSP is a unidirectional label-switched path, not a bi-directional tunnel.
