Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q297-Q302):

NEW QUESTION # 297
Router-LSA can describe different link types. Which of the following is not a Router LSA link type?

Answer: B


NEW QUESTION # 298
See the network shown in the following figure.

R1 and R2 run IS-IS and establish an adjacency. IS-IS is enabled on Loopback0 of R2 but disabled on Loopback3 of R2. The configurations shown in the figure are performed in the IS-IS process of R2. Which of the following statements are true?

Answer: A,B

Explanation:
In the provided configuration, IS-IS is enabled onLoopback0but not onLoopback3of R2. As a result, R2 will advertise the route10.0.2.2/32(fromLoopback0) to R1 through IS-IS. However, the route10.0.2.3/32will not be advertised because IS-IS is not enabled on that loopback interface. Theimport-route directcommand does not override this behavior .


NEW QUESTION # 299
Which of the following statements regarding OSPF route summarization commands are true?

Answer: A,C,D

Explanation:
The asbr-summary command is executed in the global OSPF view to summarize external routes. The abr- summary command is executed in the OSPF area view to summarize routes between areas. By default, the advertise parameter is enabled unless explicitly overridden by the not-advertise option .


NEW QUESTION # 300
From the logical architecture perspective, network devices are logically divided into multiple planes. Which of the following planes is not one of them?

Answer: B


NEW QUESTION # 301
On an STP network, only the designated port processes inferior BPDUs. On an RSTP network, a port with any role processes inferior BPDUs.

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* STP and RSTP Behavior:
* STP: Only the designated port processes inferior BPDUs. Inferior BPDUs are received from downstream switches and typically indicate topology changes.
* RSTP: All ports, regardless of role (root, designated, or alternate), process inferior BPDUs to ensure faster convergence.
* Behavior Difference:
* RSTP improves convergence by allowing any port to process inferior BPDUs, unlike STP, which restricts this function to designated ports.
