Nokia Certified Network Associate – Data Center — Question 2

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

Answer options

• 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.

Correct answer: C

Explanation

Option C is incorrect because an LSP is typically a unidirectional tunnel that forwards data in one direction using MPLS labels. The other options accurately describe how MPLS functions, with A being true about the signaling protocol, B about LSR operations, and D about the transparent data transport.
