The SNCP ring network composed of OptiX OSN 3500 equipment uses GXCSA as the cross-connect board, and the main ring is equipped with an SL64 single board. A and B are two adjacent nodes.
The station B receives a large number of errors in the regeneration section and multiplex section on the SL64 board of station A.
At the same time, station A receives the remote error code of the multiplex section reported on the SL64 board of station E.
In the networking diagram, it is found that the distance between A and B is 100km, the rate is 10G, and the configuration structure is "light board + BA + PA + DCU + light board".
Which of the following causes the error code to occur? (multiple choice)

• A.DCU module model error
• B.Error code caused by light board failure
• C.Insufficient BA+PA gain leads to bit errors
• D.Cross-board and circuit board coordination problems cause bit errors

The LPT (Link Pass Through) function is used in scenarios where WDM equipment accesses FE/GE/10GE LAN services. The correct statement about LPT is: (multiple choice)

• A.The implementation of the LPT function can be divided into port-based LPT and service-based LPT.
• B.From the network level, ALS is similar to the Link Pass Through (Link Pass Through) function. The difference is mainly reflected in the applicable services, fault transmission methods and laser restart mechanism.
• C.It enables the user equipment to perceive the link status information by turning off and turning on the laser of the wavelength division device, thereby triggering the user equipment to activate the business protection function, and select the main or backup link for communication
• D.By adding overhead bytes supporting the LPT protocol to the WDM side signal frame format, the operating status of the network access point or service network can be monitored.

NE1, NE2, NE3, NE4, and NE5 form an MSP ring, and there is an STM-1 link between NE1 and NE3. An SNCP VC-4 service is created between NE1 and NE3. The working source of this VC-4 service is on the MSP working path, and the protection source is on the STM-1 link. SNCP delay time is 100ms. When a fiber break occurs for the first time (between NE1 and NE2), the MSP switches normally. When the fiber is cut for the second time in the MSP ring (between NE3 and NE5), the SNCP service is interrupted and no SNCP protection switching occurs.
What are the solutions?

• A.Remove NE4
• B.Change the rate of STM-1 to STM-4
• C.Set HP_UNEQ alarm as SNCP switching trigger condition
• D.Delete delay time

After a maintenance person failed to start the CORBA interface, he listed several inspection steps.
1. View the log file "%IMAPROOT%/server\var\logs\Develop\nbi\Agent_CORBA\unbi_sys_yyyyMMdd_hhmmss_*.log";
2. Check whether the U2000 License file supports the U2000 CORBA interface function;
3. Check if the %IMAPROOT%/server/ns.ior file is deleted. Is his operation correct?

• A.TRUE
• B.FALSE

Which of the following features does the N3EFS4 board support? (multiple choice)

• A.QINQ
• B.LPT
• C.QoS
• D.LCAS
