Nokia Certified Network Associate – SR OS Network Administration — Question 18

Which of the following is a key benefit of active/standby pseudowires?

Answer options

• A. The MDU does not need to support MPLS.
• B. T-LDP signaling is not required.
• C. Layer 2 loop prevention protocol such as RSTP is not required.
• D. The MDU is not aware of the active/standby configuration.

Correct answer: D

Explanation

The correct answer is D because the MDU operates independently of whether the configuration is active/standby, allowing for seamless failover. Options A, B, and C are incorrect as they suggest limitations or requirements that do not accurately reflect the characteristics of active/standby pseudowires.
