Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q172-Q177):

NEW QUESTION # 172
Four routers run ISIS and have established adjacencies. The area IDs and router levels are marked in the following figure. If route leaking is configured on R3, which of the following is the cost of the route from R4 to 10.0.2.2/32?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: C

Explanation:
In the given topology, the route from R4 to 10.0.2.2/32 traverses R3, which performs route leaking from Level-2 to Level-1. The cost is calculated as follows: R4 to R3 (40) + R3 to R2 (10) + R2 to the destination (30), resulting in a total cost of 80 .


NEW QUESTION # 173
BFD provides fast fault detection independent of media and routing protocols. To use this mechanism to detect link connectivity, devices at both ends must support this feature.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* Bidirectional Forwarding Detection (BFD):
* BFD is a lightweight protocol that provides rapid fault detection on links independent of the underlying routing protocol or media.
* Requirements for BFD:
* Both devices at the endpoints of the link must support and configure BFD for it to operate.
* If one device does not support BFD, the feature cannot be used for link detection.

* Huawei BFD Configuration Guidelines


NEW QUESTION # 174
See the following figure. All routers on the network run IS-IS and are in area 49.0001. By referring to the LSDB of R1, the Level-2 DIS is. (Enter the device name, for example, R1.)

Answer:

Explanation:
R3
* Understanding the LSDB and Level-2 DIS Election in IS-IS:
* In IS-IS, the Designated Intermediate System (DIS) is elected for both Level-1 and Level-2 on broadcast networks to manage the link-state database (LSDB) and reduce the number of LSAs exchanged.
* The election of the DIS is based on the highest priority. If the priority is the same, the router with the highest System ID becomes the DIS.


NEW QUESTION # 175
When a routing policy is used to filter routes, which of the following route prefixes will be denied by the IP prefix below?

  • A. 1.1.1.1/32
  • B. 1.1.1.1/24
  • C. 1.1.1.2/16
  • D. 1.1.1.1/26

Answer: B


NEW QUESTION # 176
An engineer sets the CAPWAP heartbeat detection interval to 20 of the active link before an active/standby switchover occurs?

  • A. 60s
  • B. 20s
  • C. 90s
  • D. 75s

Answer: A

Explanation:
The CAPWAP heartbeat detection interval is typically multiplied by a predefined factor to determine the switchover time. For instance, in Huawei devices, a common default is three missed heartbeats before a switchover is triggered. With a detection interval of 20 seconds, the switchover occurs after 60 seconds (20 x
3). This ensures that transient network issues do not cause unnecessary switchovers .
