Huawei Certified Internetwork Expert-Transmission Sample Questions:
1. Which of the following descriptions are correct for error alarms (multiple choice)
A) OTUk_ES (OTUk_BEE ), ODUk_PM_ES (ODUk PM_BBE) are OTUk/ODUk errored seconds (background error block), the count is the error count of the OTUk/ODUk signal that is counted, non-zero means OTUk/ODUk signal The second in which a bit error occurred (the number of errored blocks).
B) OTUk_SES and ODUk_PM_SES are OTUk/ODUk severely errored seconds, and the count is not zero, indicating that the OTUk/ODUk signal has generated a large bit error in seconds (1 second counting error bits more than 15% of the maximum transmission byte)
C) FEC_BEF_COR_ER enables the FEC function to be effective, FEC error rate before error correction, indicating the error statistics of the received OTUk signal (including OTUk overhead), and the error rate before error is not zero, indicating the error rate introduced by the transport layer The bit error may have affected the OTUk signal.
D) FEC_AFT_COR_ER enables the FEC function to be valid. The error rate after FEC error correction indicates the error statistics of the OTUk signal (including OTUk overhead) after FEC encoding and error correction. The error after correction is not zero, which means transmission The bit error introduced by the layer may have affected the OTUk signal.
2. Which of the following abnormal conditions will trigger the TPS protection switching of the PTN equipment?
A) The work processing board is offline
B) The working interface board is offline
C) The business interface of the working interface board is loose
D) Business interruption caused by non-hardware reasons on the work processing board
3. The C-band 40-wave system is transformed into a C-band 80-wave system. The correct description is (multiple choice)
A) Unprotected networking operation process will interrupt the original business
B) The original business signal-to-noise ratio remains unchanged after operation
C) There is no change in the optical power of the OTU WDM side
D) Need to re-adjust the light emission power
4. Which of the following is not an antenna parameter?
A) 3db beam angle
B) Front-to-back ratio
C) Standing Wave Ratio
D) Antenna gain
5. The sequence of downstream signals flowing through the functional blocks of the SL16 circuit board is
A) HPT, MSA, MSP, MST, RST, SPI
B) HPT, MSP, MSA, MST, RST, SPI
C) SPI, MST, RST, MSP, MSA, HPT
D) SPI, RST, MST, MSP, MSA, HPT
