Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q278-Q283):

NEW QUESTION # 278
Which of the following statements is false about the default processing of the next hop address when a BGP device advertises a route?

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
Default Next Hop Behavior in BGP:
Locally Originated Routes (A):The next hop is set to the advertising router's interface IP address.
Routes Received from EBGP (B):The next hop is not changed when these routes are advertised to IBGP peers. (This makes Option B false.) Routes Advertised to EBGP (C):The next hop is set to the interface IP address of the advertising router.
Routes Advertised Between IBGP Peers (D):The next hop is not modified by default.
Incorrect Statement:
Option B is incorrect because the next hop of a non-labeled route received from an EBGP peer is not changed when it is advertised to IBGP peers.

NEW QUESTION # 279
On an OSPF network, routers learn routing information on the entire network by exchanging LSAs. Which of the following values is the LS Age in the LSA header when an LSA is deleted?

Answer: B

Explanation:
LSA Lifetime and Deletion
The LS Age field in the LSA header tracks the age of an LSA. When the LS Age reaches its maximum value (3600 seconds), the LSA is marked for deletion. This ensures old or stale LSAs are removed from the network to maintain accurate routing information.


NEW QUESTION # 280
As shown in the figure, STA and STB run the RSTP protocol, and the Cost of Path remains the default.

Which of the following descriptions of device and port status is correct?

Answer: A


NEW QUESTION # 281
In BGP, not only the configuration of peers becomes complicated in a fully connected IBCP network, but also the consumption of network resources and device CPU resources will increase. Which of the following techniques can be employed to simplify IBGP network connectivity?

Answer: D


NEW QUESTION # 282
An IP prefix list is a common matching tool used in routing policies. Which of the following cannot be configured as matching conditions in an IP prefix list on a Huawei router?

Answer: C

Explanation:
IP Prefix List Matching Conditions An IP prefix list matches based on:
Mask: Specifies the subnet mask length.
Action: Specifies whether to permit or deny.
Index: Orders the rules within the prefix list. Port numbers are not applicable as matching conditions in an IP prefix list.
