質問 43
As with the STP device, the NG WDM device can practice the network element configuration on the network through pre-configured method.

• A. TRUE

質問 45
The shortcomings of traditional OTDR meters in measuring optical fibers are: (Multiple choice)

• A. Manual interpretation is required, which requires high operator requirements
• B. Business will be interrupted during measurement
• C. Need inbound measurement
• D. Cannot be used for routine maintenance testing

正解: A,B,C,D

 

質問 46
Generally, in the NG WD system, the full-wave fiber input power is generally less than 20dBm. What is the main reason?

• A. To avoid nonlinear effects
• B. In order to maintain the personal safety of personnel
• C. In order to extend the life of the laser of the board
• D. In order to protect the cable

正解: A

 

質問 47
Which of the following description of the performance parameters of line fiber quality monitoring is wrong?

• A. Line fiber quality monitoring function increases the monitoring accuracy by adding the averaged results to the average. The actual time required from the start detection to the software returning the test result will be greater than the "detection time" is set.
• B. The total loss of the fiber will affect the actual detection distance. The dynamic range of the same detection mode is fixed. The larger the total loss of the fiber, the smaller the distance that can be detected.
• C. Different modes of light pulse width are different in detection, pulse width affects distance accuracy and monitoring distance. The larger the pulse width, the larger the dynamic range, the longer the test distance and the higher the range measurement accuracy.
• D. Increasing the pulse width increases the duration of the laser emission, which increases the energy injected, allowing for a larger dynamic range, but an increase in pulse width results in a larger dead zone.

正解: C

 

質問 48
When configuring the Ethernet Layer 2 attribute, set the Default VLAN ID and VLAN Priority of the untagged frame when the TAG ID is set to Accese or Hybrid. The "VLAN priority" is set according to the QoS of the unified plan.

• A. TRUE
• B. FALSE

正解: A

 

質問 49
For the MSTP equipment, the pass-through mode is used for VC-4 services by default, and the termination mode is used for VC12/VC3 services by default.

• A. True
• B. False

正解: A

 

質問 50
Since the nonlinear effect is generated, its influence on the service signal cannot be repaired. Therefore, the treatment of the nonlinear effect of the existing network is to avoid the occurrence of nonlinear effects.

• A. TRUE
• B. FALSE

正解: A

 

質問 51
Which of the following device types support the master-slave sub-architecture mode? (Multiple Choice)

• A. OSN 9800
• B. OSN 8800

質問 52
The following description of the Directioned scenario, which is correct? (Multiple choice)

• A. Directioned scenes are applied to networks that are not ASON.
• B. The wavelength carrying the local service can be transmitted to fixed direction.
• C. When the service needs to be adjusted, or the working path is faulty, the optical crossover can be manually configured to implement flexible scheduling of services.
• D. If the current path needs to be adjusted, you must inbound to adjust the fiber connection of the network.

正解: A,B,D

 

質問 53
The OTN circuit board (such as ND2) of OSN 1800V can respond to the status of the indicator light on the panel to reflect the optical power of the local end too high or too low.

• A. TRUE
• B. FALSE

正解: B

• A. 1491nm
• B. 1510nm
• C. 1471nm
• D. 1511nm

正解: D

 

質問 55
Which of the following statements about replacing the SCC board is incorrect?

• A. If the software version of the new SCC board is later than equipment version, clear the database of the SCC board, and then downgrade the software on the SCC board to the same version as the equipment.
• B. In the case of the 1 + 1 hot backup of the SCC board, replacing the control board does not affect services when the active/standby switchover is performed.
• C. After the SCC board is removed, the BD_STATUS and COMMUN_FAIL alarms are reported. After the new board goes online, these alarms need to be manually cleared.
• D. If the software version of the new SCC board is earlier than the equipment version, upgrade the software on the SCC board to the same version as the equipment.

正解: C

 

質問 56
Which of the following statement is correct?

• A. When the OCh path exists, you can directly create a client path. The NMS automatically creates an ODUk path.
• B. The optical layer path and the electrical layer path are independent. It is not necessary to delete the electrical layer path when deleting the optical layer path.
• C. Deactivation will delete the configuration of the U2000, which has no impact on the device side services.
