Huawei Certified Network Professional-Building Carrier OTN Transmission Network Sample Questions:

1. Regarding the configuration of the electrical layer service, which of the following statements is wrong.

A) In the case where the OCh service path exists, the ODUk path is directly created, and the network management can automatically create the OTUk path.
B) In the case of the OCh service path, you can search for the OTUK path, create the ODUk service layer path, and create the client path.
C) After the logical fiber connection is completed, the path search operation is not required, and the OTS path and the OMS path can be automatically generated.
D) In the case where the OCh service path exists, the client path is created directly, and the NMS can automatically create the OTUk and ODUk paths.

2. When the OCH is created by the path method, you do not need to configure the wavelength of the WDM side port of the source and the OTU board.

A) True
B) False

3. The boundary port needs to be configured before creating a single-station optical crossover and creating a single-board optical crossover.

A) True
B) False

4. Which of the following is a description of the SCC function from the subrack? Which one is wrong?

A) Protection switching protocol processing of this subrack
B) From the subrack board status management
C) Processing of overhead
D) DCN message forwarding

5. OTU is one of the important components of the WDM system. Which of the following is wrong about OTU?

A) -20dB spectral width, side mode suppression ratio, center wavelength, frequency offset, etc. are all important parameters or indicators to measure the OTU wave side transmitter.
B) The greater the dispersion tolerance of the transmitter, the farther the signal can transmit without dispersion compensation.
C) Sensitivity and overload point are important parameters/indicators for measuring the OTU receiver. The sensitivity of the PIN receiver is better than that of the APD.
D) The most basic function of the originating OTU is to perform wavelength conversion to convert the wavelength of the signal that is not suitable for WDM system transmission to the wavelength that meets the transmission requirements of the WDM system.
