Huawei H13-341 Exam Questions & Answers

Which of the following statements about the line fiber quality monitoring performance parameters is wrong?

A. The pulse width of emitted optical pulses varies according to monitoring modes, and affects the detection distance and measurement precision. A greater pulse width provides a larger dynamic range, longer detection distance and better measurement precision.

B. When the pulse width increases, the light emitting time increases and consequently a larger energy is obtained. This means that a larger dynamic range can be acquired but also larger dead zones will result.

C. Measurement is performed multiple times within the detection time. The average value is obtained based on the measurement result to improve the measurement precision. The actual duration from the time when a detection event starts to the time when the detection results are returned will be longer than the Detection time.

D. The total fiber loss will affect the detection distance and dynamic range is fixed for the same detection mode. Therefore, a larger total fiber loss indicates a smaller detection distance.

MPLS tunnel APS protection supports multiple types of command switching and has different priorities. Which of the following commands switching types has the highest priority?

A. Locked Switching

B. Practice Switching

C. Force Switching

D. Manual Switching

The overhead ratio is a factor that affects the error correction capability of the FEC technology. Generally, when the same FEC encoding/decoding is used, the higher the overhead ratio is, the larger the net coding gain is.

A. True

B. False
