Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q227-Q232):

NEW QUESTION # 227
As shown in the figure, when R2 passes the route of 10.0.1.0/24 to R3, which of the following is the Next_Hop address of the route?

Answer: D


NEW QUESTION # 228
In the VRP, by default, the routes imported by BGP will be automatically summarized.

Answer: A

Explanation:
By default, BGP does not automatically summarize imported routes. Route summarization must be explicitly configured using the summary or similar commands .


NEW QUESTION # 229
A large number of routes typically exist in a BGP routing table, and transmitting such extensive routing information brings a heavy burden to a device. In order to address this problem, it is necessary to filter those routes to be advertised. You can configure a device to advertise only necessary routes or those that its peers require.

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* BGP Route Filtering:
* BGP provides flexible policies for route filtering to optimize routing table size and reduce network resource usage.
* By configuring route filters, a device can advertise only required routes to peers, thereby improving efficiency.
* Purpose of Filtering:
* Reduces the routing table size.
* Decreases CPU and memory usage on routers.
* Limits unnecessary route propagation.

* HCIA-Datacom Study Guide, Chapter: BGP Policy Control
* Huawei BGP Route Filtering Configuration


NEW QUESTION # 230
An enterprise administrator wants to configure single-hop BFD to implement fast detection of direct links.
Which of the following configurations are mandatory?

Answer: B,C,D

Explanation:
For single-hop BFD (Bidirectional Forwarding Detection), the configuration must include the local and remote discriminators to uniquely identify the session endpoints. Additionally, enabling BFD globally is a prerequisite for initiating BFD sessions. Configuring multicast IP addresses is unnecessary for single-hop BFD, as it operates over direct links. Huawei's configuration guidelines specify these requirements to ensure effective deployment and operation of BFD.
Understanding BFD (Bidirectional Forwarding Detection):
* BFD is a protocol used to detect link faults quickly between two routers.
* Single-hop BFD operates on directly connected links and is commonly used for fast fault detection in routing protocols like OSPF and BGP.


NEW QUESTION # 231
STP ensures a loop-free network but has a slow network topology convergence speed, affecting communication quality. RSTP has made some improvements based on STP. Which of the following improvements is not included?

Answer: D

Explanation:
RSTP improves convergence by introducing changes to the BPDU handling mechanism and port roles.
However, RSTP does not rely on a fixed timeout of four Hello intervals for negotiation failure. Instead, RSTP uses a more dynamic mechanism to detect topology changes. The other options describe valid RSTP improvements .
