Question 87

In the path search process of the U2000 network management, the path search management module first scans the cross-connections of each network element, constructs sub-paths according to the cross-connections of adjacent network elements, and tries to merge these sub-paths at the same time. Which of the following sub-paths is legal?

A.Subpaths form a loop

B.The original destination is not the end point of the subpath or the optical port of the subnet

C.The path does not pass through the fiber

D.The sub-path terminates on the pre-configured network element
