Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q704-Q709):NEW QUESTION # 704
BGP can select routes based on the AS_Path attribute. Therefore, in some cases, a route-policy needs to be used to modify the AS_Path attribute for route selection. Which of the following parameters can be specified in the apply as-path command for a route-policy to modify this attribute?
  • A. Delete
  • B. Copy
  • C. Overwrite
  • D. Additive
Answer: A,C,D
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of AS_Path Attribute Modification:
The apply as-path command in a route-policy is used to modify the AS_Path attribute of routes. This is often required to influence the selection of routes or to adjust routing policies for incoming or outgoing BGP updates.
2. Parameters of the apply as-path Command:
Option A: Delete
* Correct.
* The delete parameter removes specific AS numbers from the AS_Path attribute. This is used to simplify or manipulate the AS_Path for specific routing policies.
Option B: Additive
* Correct.
* The additive parameter appends an AS number to the existing AS_Path attribute, instead of overwriting it. This is useful when you want to prepend AS numbers to influence route selection without removing the original AS_Path.
Option C: Copy
* Incorrect.
* The copy parameter is not supported in the apply as-path command for modifying AS_Path attributes.
Option D: Overwrite
* Correct.
* The overwrite parameter replaces the existing AS_Path with a new one. This provides complete control over the AS_Path attribute but removes the original AS_Path entirely.
3. Summary:
The valid parameters for the apply as-path command are delete, additive, and overwrite.

NEW QUESTION # 705
An enterprise administrator wants to configure single-hop BFD to implement fast detection of direct links.
Which of the following configurations are mandatory?
  • A. Configure a multicast IP address for BFD.
  • B. Enable BFD globally.
  • C. Configure the remote discriminator of a BFD session.
  • D. Configure the local discriminator of a BFD session.
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.
