1. In the extended SSM ring network dual BITS clock protection scenario, in order to prevent the clock signal from forming a loop, you only need to configure the external clock source and internal clock source ID of the network element connected to the active BITS, and the network element connected to the standby BITS does not need to configure the internal clock ID.

FALSE

2. Regarding the description of replacing the main control board, which is wrong?

The BD_STATUS and COMMUN_FAIL alarms will be reported when the main control board is removed and inserted. After the new board goes online, these alarms need to be cleared manually.

If the software version carried on the replaced main control board is higher than the device version, you need to clear the main control library first, and then downgrade the main board software to the same version as the device.

If the software version locked on the replaced main control board is lower than the device version, you need to upgrade the software on the main control board to the same version as the device

When the main control board has 1+1 hot backup, under normal switching conditions, the replacement of the main control board will not affect the business.

8. The following description about ODUk ring network protection, which is wrong?

ODUk ring network protection is mainly used in ring networking with distributed services. By occupying two different ODUk channels, it can protect multiple distributed services between all sites.

The protection configuration of each site on the ring network must be completed before starting the agreement.

Adjust the adjustable optical attenuation before the receiving amplifier to increase the input optical power of the amplifier

14. How much dBm is 100mw approximately equal to?

10dBm

15dBm

20dBm

13dBm

15. Overhead ratio is a factor that affects the error correction capability of FEC technology. Generally, under the same FEC encoding/decoding algorithm conditions, the higher the overhead ratio, the greater the net coding gain.

TRUE

FALSE

16. The OSN 8800 equipment adopts fan redundancy protection. When any fan in the fan box fails, the system can still operate normally for a long time.

TRUE

FALSE

17. Which of the following are the logical ports on the client side of the board in the standard mode?

n(Nn/OUTn)-OCH: 1-ODUk: m-ODUp: a

ClientLP-n

ODUkLP-n

18. Which of the following is not a function of RSVP-TE?

LSP path optimization

LSP deletion

LSP rerouting

Establish neighbor relations

19. The following statement about the alarm reversal function, which is wrong?

For ports that have not opened services, alarm reversal is used to avoid related alarms

By default, it is non-reverse mode. In this mode, the alarm of the device port cannot be reversed.

In automatic recovery mode, regardless of whether the port currently has an alarm or not, the port device alarm can be reversed

After the port device alarm is reversed, no alarm is reported when there is an actual alarm, and an alarm is reported when there is no actual alarm.

172.128.0.1

10.255. 0.1

10.0.0.1

Input optical power of the receiving end OTU

28. The following description about using the synchronization method to create optical fibers, which is wrong?

There is no need to create an optical fiber with the same information on both the network management side and the network element side.

If there are optical fibers that have not been created on the network management system or optical fibers that have not been created on the network element, they need to be synchronized or created.

The existence of conflicting fibers does not affect the configuration of the path, so you can ignore it

Conflicting fiber refers to the fiber that has been configured on the network element side that is inconsistent with that on the network management side.

Intra-office mode

Near-end mode

TRUE

FALSE

32. When the main control board is configured with a single board, which step is required to replace the single board than when the main control board is configured with a dual configuration?

Download the original configuration data

Ensure that the host software version is the same before and after the replacement. If it is inconsistent, please upgrade and replace the single board software first.

Check the consistency of network management and network element data.

Query the board alarm and confirm that the original alarm has been cleared.

33. When the value of S1 byte is 0x02, it means ？

34. The compensation of the chromatic dispersion of the WDM system mainly adopts the DCM compensation method. The following statement about DCM dispersion compensation, which is wrong?

Improper DCM configuration will lead to degradation of system signal-to-noise ratio.

For 10G systems with line fiber length within 400km,
