Question #: 44
Topic #: 6
[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.

Wait, isn't the data 'transparently carried from end to end' in MPLS networks? I'm a bit confused now.

Haha, I bet the person who wrote this question was trying to catch us off guard. Time to brush up on my MPLS knowledge!

The question is a bit tricky. I think the correct answer is C, as an LSP is a unidirectional tunnel, not a bi-directional one.

Hmm, I'm not sure about that. Aren't MPLS labels used to forward data in both directions? I'll have to double-check the MPLS fundamentals.
