If the OSN6800 device wants to achieve 1588V2 time synchronization, it must be configured with an electrical crossover board

• A.FALSE
• B.TRUE

In the Ethernet service OAM, the name of the node that can initiate the OAM operation is

• A.MEP
• B.MIP
• C.MA
• D.MD

Which of the following descriptions are correct for error alarms (multiple choice)

• A.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.
• 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.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)

In the process of U2000 network management searching for paths, the path search management module first scans the cross-connections of each network element, constructs sub-paths based on the cross-connections of adjacent network elements, and tries to merge these sub-paths.Which of the following sub-paths are legal?

• A.The path does not go through the fiber
• B.The sub-path ends on the pre-configured network element
• C.The sub-path forms a loop
• D.The source and sink are not the end point of the sub-path or the optical port out of the subnet

The IP address you use is 165.247.52.119, and the subnet mask is 255.255.240.0. Which subnet is your host?

• A.165.247.52.0
• B.165.247.48.0
• C.165.247.56.0
• D.165.247.32.0
