Question 56

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

A.Circuit scheduling is created and configured using network management end-to-end path management

B.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

C.For cross-network management services, landing through virtual network elements

D.Paths with protected routes need to be tested for fiber breakage or switching to ensure that the configuration is complete and standardized

Question 57

For WDM networks, the following descriptions are correct

A.For OAU boards, the type of DCM module connected on site can be roughly judged based on the difference between the output of POUT and the input of BAIN

B.For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 100G

C.For OAU boards, you can roughly judge the type of DCM module connected to the site according to the upper threshold of nominal gain (dB) on the network management system-the upper threshold of actual gain (dB)

D.For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 10G

Question 58

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 sub-path forms a loop

B.The source and sink are not the end point of the sub-path or the optical port out of the subnet

C.The sub-path ends on the pre-configured network element

D.The path does not go through the fiber

Question 59

172.17.15.0/28 When dividing subnets, which of the following addresses are legal subnet addresses (multiple choice)

A.172.17.15.40

B.172.17.15.0

C.172.17.15.96

D.172.17.15.8

Question 60

For WDM network, the following description is correct (multiple choice)

A.For 10G and 100G mixed transmission networks, you can use the performance of 10G to analyze the dispersion compensation of the system

B.For an OAU board, you can roughly judge the type of DCM module connected to the site according to the upper threshold of nominal gain (dB) on the network management system and the upper threshold of actual gain (dB)

C.For the OAU board, the type of DGI module connected on site can be roughly judged based on the difference between the output of POUT and the input of BAIN

D.For 10G and 100G mixed transmission networks, you can use the performance of 100G to analyze the dispersion compensation of the system
