Nokia Certified Network Associate – Data Center — Question 34

Which of the following statements about Segment Routing is FALSE?

Answer options

• A. No path signaling is required to establish an SR tunnel.
• B. Intermediate routers do not maintain any tunnel information.
• C. A link-state IGP is required to distribute SID information.
• D. For TE-constrained tunnels, each data packet typically carries a single MPLS label to specify the tunnel path.

Correct answer: D

Explanation

The correct answer is D because, in TE-constrained tunnels, multiple labels may be used to represent the tunnel path instead of just a single MPLS label. Options A, B, and C are true statements about Segment Routing, as it allows for efficient routing without the need for signaling, does not require intermediate routers to retain tunnel data, and utilizes a link-state IGP for SID distribution.
