Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions:
Route summarization can effectively reduce the number of BGP routes. However, many parameters need to be properly set when configuring BGP route summarization. Otherwise, problems such as routing loops may occur.
Which of the following statements is false about BGP route summarization?
- A. If the summary automatic command is run on a device, the device summarizes subnet routes based on natural network segments.
- B. If the aggregate command with detail-suppressed specified is run on a device, the device advertises only the summary route.
- C. If the aggregate command is run on a device, the device advertises both specific and summary routes.
- D. If the aggregate command with suppress-policy specified is run on a device, the device advertises only the specific routes that match the given routing policy.

- A. FALSE
- B. TRUE

Which of the following scenarios is not suitable for deploying interface PBR?
- A. On an enterprise network with multiple ISP outbound interfaces, each internal network segment accesses the Internet through a particular ISP outbound interface.
- B. A device needs to modify the next-hop IP address for locally originated traffic.
- C. A core switch needs to forward the traffic between the intranet and extranet to a security detection device that connects to the core switch in off-path mode.
- D. A core switch needs to forward traffic between the intranet and extranet to an AC device that connects to the core switch in off-path mode.

In BGP, the Origin attribute is used to identify the origin of a route. Which of the following statements are true about the Origin attribute?
- A. If a route is imported to BGP by the originator using the network command, the Origin attribute of the BGP route is displayed as i in the BGP routing table.
- B. If multiple routes carry the same destination address but different Origin attributes and all other route selection conditions are the same, BGP selects the optimal route according to the Origin attribute in the following order: IGP > EGP > Incomplete.
- C. If a route is learned through EGP, the Origin attribute of this BGP route is displayed as ? in the BGP routing table.
- D. This attribute is a well-known mandatory attribute.

When receiving a packet, a Huawei router matches the packet against ACL rules. The default ACL matching order used by the Huawei router is.
Sequential
Explanation:
ACL Matching in Huawei Routers:
* Access Control Lists (ACLs) are used to filter packets based on specific criteria, such as source
/destination IP, ports, or protocols.
* When a packet arrives, the Huawei router processes it against the configured ACL rules to decide whether to permit or deny the packet.
Reference: HCIP-Datacom-Core Technology Training Material (ACL Principles and Configuration).
Sequential Matching Order:
By default, Huawei routers match packets against ACL rules sequentially. This means:
The router checks the packet against rules in the order they are listed, starting from the top of the ACL.
The first rule that matches the packet ' s attributes is applied, and no further rules are checked. This is known as the first-match principle.
If no rules match, the packet is denied by default (implicit deny).
Reference: HCIP-Datacom Advanced Routing & Switching Technology (ACL Matching Mechanism).
Example of Sequential Matching:
Consider the following ACL rules:
Rule 10: Permit IP 192.168.1.0/24
Rule 20: Deny IP 192.168.1.1
If a packet with source IP 192.168.1.1 arrives:
The router matches it against Rule 10 (Permit 192.168.1.0/24) and allows the packet.
Rule 20 is not evaluated because the first match (Rule 10) already applies.
Alternative Matching Orders:
Some routers or configurations allow batch matching (evaluating all rules) for specific scenarios, but this is not the default behavior in Huawei routers.
Conclusion:
The default ACL matching order on Huawei routers is sequential, and the first matching rule determines the action applied to the packet.
