Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q164-Q169):

NEW QUESTION # 164
BGP is generally applied to complex networks where routes change frequently. Frequent route flapping consumes a large number of bandwidth and CPU resources, and even affects the normal operation of the network. This is an unavoidable problem that cannot be solved in BGP.

A. FALSE
B. TRUE

Answer: A

Explanation:
BGP Route Flapping and Mitigation
* While route flapping is a concern in large-scale networks, BGP employs mechanisms such as Route Dampening to mitigate its impact. Route dampening suppresses frequently flapping routes for a period of time to reduce resource consumption and network instability.
* Therefore, it is incorrect to state that the issue cannot be resolved in BGP.
HCIP-Datacom-Core Reference
* The mechanism of route dampening is detailed in the BGP optimization chapters.

NEW QUESTION # 165
By default, if no router ID is configured but multiple loopback interface addresses are configured, BGP selects the largest loopback interface address as the router ID.

A. FALSE
B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* BGP Router ID Selection Rules:
* If a router ID is not manually configured:
* The largest loopback address is selected as the router ID.
* If no loopback interfaces exist, the largest active physical interface address is selected.
* Default Behavior:
* This ensures that a stable and unique router ID is chosen automatically, even without manual configuration.

NEW QUESTION # 166
Regarding the route-policy set-cost configuration below, which of the following statements is true?

A. The cost of all routes is set to 200.
B. The route 11.1.0.0/16 is permitted by node 10, and its tost Is set to 300.
C. All the routes that are not permitted by node 10 will be denied.
D. The route 11.1.0.0/16 will continue to match node 20 after permitted by node 10, and (he final cost is set to 200.

Answer: B

Explanation:
The route-policy configuration specifies that node 10 matches the IP prefix 11.1.0.0/16 and applies a cost of
300 to this route. Once a route matches a node, it is no longer processed by subsequent nodes, making option D incorrect. Option B is also incorrect because only specific matching routes have their costs changed .

NEW QUESTION # 167
Which of the following statements regarding the firewall zone security level is false?

A. The default security level of the new zone is 1.
B. Two zones cannot be configured with the same security level.
C. Only the security level of the user-defined zone can be configured.
D. The configured security level cannot be changed.

Answer: D

NEW QUESTION # 168
RSTP provides different functions in different scenarios. Which of the following statements Is false?

A. The role of the designated port that is enabled with root protection cannot be changed
B. After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period
C. When the designated port enabled with root protection receives optimal RST BPDUs, the port enters the Discarding state and does not forward packets. If the port does not receive optimal RST BPDUs within a certain period of time, the port will automatically restore to the Forwarding state
D. If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation

Answer: D
