CCDE: Cisco Certified Design Expert (Written) — Question 17

You have been hired by a startup company to provide optical services using MPLS-TP. Which three options describe reasons to use the MPLS-TP standard in your design? (Choose three.)

Answer options

• A. MPLS-TP is a newer packet transport technology that replaces SONET/SDH.
• B. MPLS-TP includes extensions to native MPLS OAM for fault detection, monitoring, and propagation.
• C. MPLS-TP requires a routing protocol.
• D. MPLS-TP uses an IANA assigned label 13 for OAM.
• E. MPLS-TP uses Ethernet Y.1731 OAM.

Correct answer: A, B, D

Explanation

The correct answers are A, B, and D because MPLS-TP indeed replaces traditional SONET/SDH technology, adds useful OAM features for fault management, and specifically employs label 13 for OAM. Option C is incorrect as MPLS-TP operates without requiring a routing protocol, and option E, while related to OAM, does not specifically apply to MPLS-TP.
