Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions:

1. In the OSPF network shown in the figure, the cost value of the link has been marked in the figure.
R1 has enabled OSPFIP FRR. Which of the following descriptions are correct? (Multiple choice)

A) If the link between R1 and S1 is disconnected, R1 directly uses the backup path to reach R3
B) If the S1 device loses power, R1 directly uses the backup path to reach R3
C) If the BFD detection function is enabled on the entire network (the detection parameters are set to the default values), when the link between R2 and S1 is disconnected, R1 can quickly detect the OSPF adjacency failure.
D) R1 cannot form a backup path to 10.0.3.3/32

2. In the network shown in the figure, OSPF protocol is deployed between R2 and R1, and OSPF protocol is also enabled on GE0/0/1 interface of R2. IS-IS protocol is deployed between R2 and R3. In order for R1 to obtain the route to 10.0.3.3/32, IS-IS route is introduced into OSPF route on R2. Then, in the routing table of R1, the next hop address to 10.0.3.3/32 is ().

3. In a certain MPLS network, the LSP information of R1 and R3 is shown in the figure. At this time, the administrator enters the command ping -a 1.1.1.1 3.3.3.3 on R1. Which of the following descriptions of this scenario is correct?

A) The Echo Request message received by R2 does not carry a label, and the Echo Reply message received by R2 does not carry a label either.
B) The Echo Request message received by R2 carries label 1025, and the Echo Reply message received by R2 carries label 1024
C) The Echo Request message received by R2 does not carry a label, and the Echo Reply message received by R2 carries label 1024
D) The Echo Request message received by R2 carries label 1025, while the Echo Reply message received by R2 does not carry a label.

4. For high reliability purposes, the following LDP messages are transmitted through TCP: discovery messages, session messages, advertisement messages, and notification messages.

A) TRUE
B) FALSE

5. On the OSPFv3 network shown in the figure, OSPFv3 is enabled on the interfaces connecting R1, R2, and R3. The router ID of each router is 10.0.X.X, where X is the number of the router. If you check detailed information about an LSA on R3, the command output shows that the LSA is generated by R2 and describes the IPv6 prefix address associated with the Router-LSA.

A) TRUE
