Huawei Exam H31-161 Topic 4 Question 92 Discussion

Actual exam question for Huawei's H31-161 exam

Question #: 92
Topic #: 4

Which of the following statements about the working principle of LDP FRR are true?

AAfter LDP FRR is enabled, a backup LSP is generated. Both the primary and backup LSPs are stored in the forwarding table.

BLDP FRR can be deployed on the ingress node and the intermediate node.The primary and backup LSPs are recorded in the ILM table on the intermediate node and in the FIB table on the ingress node.

CMultiple LSPs can be backed up on the ingress node, that is, entries about multiple backup LSPs are generated in the forwarding table according to the priority of the LDR FRR, implementing multilayer protection.

DAfter LDP FRR is enabled, a backup LSP can be generated for a primary LSP to prevent serious packet loss during fast flapping of the primary LSP

Option D is also a valid point. Having a backup LSP ready to go can definitely help minimize packet loss during network flaps. Gotta love those redundancy features!

It's great to have that extra layer of protection in case of fast flapping in the primary LSP.
