Huawei Certified Internetwork Expert-Transmission Sample Questions:
Question #1
Hybrid MSTP devices support cross-domain clock intercommunication, and support the intercommunication of synchronous Ethernet and SDH synchronization.
- A. FALSE
- B. TRUE
Correct Answer: B π³οΈ
Question #2
Use the integral method to measure the OSNR value of a 100G signal, read from the OSA, the integrated value of the signal power + noise power in the channel interval is 9.68uW, the integrated value of the noise power in the channel interval is 29.58nW, and the signal center frequency is within 0.1nm. The integrated power is 7.395nW, the OSNR value is ()?
- A. 10log [(9.68+0.007395)/0.02958]
- B. 10log [(9.68-0.007395)/0.02958]
- C. 10log [(9.68-0.02958)/0.007395]
- D. 10log [(9.68+0.02958)/0.007395]
Correct Answer: C π³οΈ
Question #3
Regarding the electrical layer protection ODUk SNCP and branch SNCP, which one is different in the following description
- A. Working principle
- B. Protection scope
- C. Protection subtype
- D. Crossing particles
Correct Answer: B π³οΈ
Question #4
Which of the following descriptions are correct for error alarms (multiple choice)
- A. 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)
- B. 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.
- C. 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).
- 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.
Correct Answer: A,C,D π³οΈ
Question #5
