문제5

Before creating an optical cross-connection, you need to manually configure the corresponding port of the corresponding board as a boundary port, for example, the line-side port of the FIU board between two sites.

A. FALSE

B. TRUE

정답: B

문제6

When the NNI port attribute is configured on the same subnet, the IP addresses of the ports on different links can be duplicated.

A. FALSE

B. TRUE

정답: B

문제7

Two PIU/APIU boards use the hot backup mode to supply power to the system on the OSN 1800 device, when a PIU/APIU board fails, the system can still work normally.

A. FALSE

B. TRUE

정답: B

문제8

Which of the following description of ODUk ring protection is wrong?

A. ODUk ring network protection is mainly applied to the ring network configuration of distributed services. It protects multiple distributed services between all sites by occupying two different ODUk channels.

B. The agreement must be completed after the protection configuration of each site on the ring network is completed.

C. Ordinary ODUk ring network protection does not require setting a management node.

D. Enhanced ODUk ring network protection, no need to set up management nodes. If the management node is set, there is no impact on protection.

정답: D

문제9

Before querying the error and optical power on the network management, you need to perform the () operation. Otherwise, you cannot query the corresponding teaching data.

A. Turn on NE performance monitoring time.

B. Configuration data

C. Synchronizing network metadata

정답: A

문제10

Which of the following description are wrong about the path method to create a Client path?

A. If the route to be automatically calculated is different from the planned path, you can set the "constrained node" or "must pass through the node" to perform routing constraints.

B. Create a client service path by using the path method. After the creation, the optical layer OCh path is automatically generated to reduce the secondary teaching of the path creation.

C. Select the "Activate" checkbox. After the path is successfully created, it will be delivered to the NE layer. Otherwise, the path configuration text will only be saved on the network management side.

D. The creation or search of a new path must be possible if its upper service layer path already exists.

정답: B

문제11
