Which of the following statements about Multi-Protocol Label Switching networks is FALSE?
A.
MPLS uses a signaling protocol to exchange labels between routers.
B.
An LSR forwards data based on the MPLS labels.
C.
An LSP is a bi-directional tunnel that uses MPLS labels to forward data.
D.
The data is transparently carried from end to end.
The Answer Is:
D
This question includes an explanation.
Explanation:
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.
