H31-341 Exam Question 26

When creating single station optical crossover, an error message "The direction of the cable is wrong selected" appears. The possible reason is?

A.Lack of logic fiber between boards

B.Device physical fiber connection error

C.The network element management time is not synchronized.

D."Create reverse crossover" is not selected during configuration

H31-341 Exam Question 27

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

C.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.

D.Measurement is performed multiple times within the detection time. The average value is obtained based on the measurement results 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.

H31-341 Exam Question 28

When you delete a discrete service, you can first activate it. At this time, you can view the alarm. If there is no alarm such as PS or TU-AIS, it is a garbage service. If there is an alarm, the analysis is incorrect. You need to activate it immediately.

A.TRUE

B.FALSE

H31-341 Exam Question 29

What should I pay attention to when commissioning a 100G and 10G hybrid transmission system? (Multiple Choice)

A.For a hybrid transmission system with dispersion compensation, the dispersion compensation requirements are consistent with the requirements in a 10G non-coherent system.

B.Pay attention to the mixed spectrum. The spectrum of the 100G signal is wider and looks lower than the 100G signal in the spectrum, but the actual optical power is equivalent.

C.In order to accurately measure the optical power of 100G wavelength, it must be debugged using a spectrum analyzer or a MAC card.

D.The optical power of the 100G signal is recommended to be higher than the optical power of the 10G signal, but not higher than the single-wave nominal value of the optical panel.

H31-341 Exam Question 30

In general, which of the following operations will cause a short interruption in monitoring of existing network devices? (Multiple Choice)

A.Hard reset main control board

B.Software loopback

C.Soft reset main control board

D.Hardware loopback
