Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q20-Q25):

NEW QUESTION # 20
Which of the following statements regarding Local-Preference in BGP is true?

A. The default Local-Preference value is 100.
B. Local-Preference is a well-known mandatory attribute.
C. Local-Preference affects traffic that enters an AS.
D. Local-Preference can be transmitted between ASs.

Answer: A

Explanation:
The Local-Preference attribute is used within an AS to influence outbound traffic paths. The default value is
100, and it is a well-known discretionary attribute, meaning it is not mandatory and does not travel across AS boundaries .

NEW QUESTION # 21
A firewall receives a packet that PC1 sends to PC2. Which of the following statements are true?

A. The packet matches security policy rule 1, and the firewall forwards the packet.
B. No source or destination security zone is specified in security policy rule 2, indicating that any security zone is a match.
C. The packet matches security policy rule 1, and the firewall discards the packet.
D. The packet does not match any security policy.

Answer: A

Explanation:
The security policy specifies that traffic originating from 12.1.1.2 and destined for the untrust zone is permitted. Since the source address of the packet (12.1.1.1) does not match this rule, the packet matches the default implicit deny rule. However, rule 1 does not deny all other traffic explicitly, so the packet is forwarded based on further configurations .

NEW QUESTION # 22
On an OSPF or IS-IS network, the filter-policy import command can be run on a router to filter out the LSAs forwarded by its neighbors.

A. TRUE
B. FALSE

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding LSA Filtering in OSPF and IS-IS:
* The filter-policy command is used in OSPF and IS-IS to control which routing information is imported into the local routing table or advertised to other neighbors.
* However, it cannot filter LSAs forwarded by neighbors. In OSPF and IS-IS, LSAs are always forwarded unchanged within the area to ensure all routers have a consistent link-state database.
* Filtering only affects the routes that are installed into the local routing table or advertised to other areas or neighbors.
2. Why the Statement is False:
* LSAs are forwarded without being filtered. This ensures link-state protocols maintain the same network topology view across the network.
* The filter-policy import command only controls routes that are installed into the local routing table, not the forwarding of LSAs.
3. Summary:
* The statement is FALSE because LSAs cannot be filtered by filter-policy import.

NEW QUESTION # 23
BFD control packets are encapsulated in UDP packets for transmission. What is the destination port number of multi-hop BFD control packets?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
BFD control packets are encapsulated in UDP packets, and the destination port number for multi-hop BFD control packets is 4784. This is a standardized port for multi-hop BFD operation .

NEW QUESTION # 24
Which of the following statements regarding the MED value in BGP are true?

A. According to BGP route selection rules, the MED value has a lower priority than AS_Path, Preferred- Value, Local-Preference, and Origin.
B. By default, if there is no MED value in routes, the value 0 is used. If the bestroute med-none-as- maximum command is configured, the maximum MED value 4294967295 is used.
C. The default MED value of BGP routes is 0.
D. By default, BGP can compare the MED values of routes from different ASs.

Answer: A,B

Explanation:
The MED (Multi-Exit Discriminator) is an optional, non-transitive attribute used to influence the exit path.
MED is considered after attributes such as Local-Preference, AS-Path, and Origin during route selection. By default, if a MED value is missing, it is treated as 0 unless the bestroute med-none-as-maximum command is configured to treat it as 4294967295 .
