Add a new single-board TOA on the live network 8800 (version R7C02SCP300), the network manager queries the TOA single-board software and cannot automatically match the R7 version of the master. The possible reason is (multiple choice)

• A.8800 equipment automatic matching software function is closed
• B.The 8800 device does not have the function of automatic matching software, and the software package needs to be reloaded
• C.The original main control of the 8800 device is a customized package, and there is no software for the TOA board, so the version cannot be automatically matched
• D.TOA's software version is higher than the live network version, so it cannot be automatically matched

The common models of Qos mainly include Best Effort model, Integrated Service model, Differentiated Service model. Which one is the Differentiated Service model described below?

• A.Forward all services as much as possible, regardless of service category
• B.Maintain the forwarding status of each data stream
• C.Reserve resources for each data stream
• D.Classify and mark data streams

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.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.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).

Which of the following descriptions of the networking requirements for configuring SOM is wrong ()?

• A.The outbound optical amplifier at the originating end of the OMS segment must be configured with an MCA board
• B.OSC board must be configured in the network
• C.An OA board must be configured between the FIU board at the receiving site of the OMS segment and the ROADM board or the split/multiplexer board
• D.Optical amplifier boards of the same dimension can be inserted into different network elements

Among the following methods, which is the most effective way to avoid discrete business?

• A.For services that use command line or network management to configure single-site SDH services, route search must be performed on the network management to ensure that the service configuration is complete and standardized
• B.For cross-network management services, landing through virtual network elements
• C.Paths with protected routes need to be tested for fiber breakage or switching to ensure that the configuration is complete and standardized
• D.Circuit scheduling is created and configured using network management end-to-end path management
