Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q222-Q227):

NEW QUESTION # 222
PBR is a mechanism for selecting routes based on user-defined policies. There are two types of PBR:
interface-based PBR and local PBR. Which of the following statements is false about these two types of PBR?

A. Local PBR takes effect only for locally originated packets.
B. Interface-based PBR takes effect only for forwarded packets.
C. Local PBR is configured in the protocol view.
D. Interface-based PBR is configured on an interface and takes effect only for incoming packets on the interface.

Answer: C

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of PBR (Policy-Based Routing):
Policy-Based Routing (PBR) allows you to override traditional routing decisions by defining user-specific policies.
Interface-Based PBR: Applied to packets arriving at a specific interface and affects traffic being forwarded through the device.
Local PBR: Applied to traffic generated by the local router itself (e.g., locally originated packets such as management traffic).
2. Analysis of Each Statement:
Option A: Interface-based PBR takes effect only for forwarded packets.
Correct (True Statement).
Interface-based PBR applies only to packets arriving at a specific interface and being forwarded through the router. It does not affect locally originated traffic.
Option B: Local PBR takes effect only for locally originated packets.
Correct (True Statement).
Local PBR specifically applies to traffic generated by the router itself, such as pings, SNMP requests, or routing protocol updates.
Option C: Interface-based PBR is configured on an interface and takes effect only for incoming packets on the interface.
Correct (True Statement).
Interface-based PBR is applied directly on the interface using commands like policy-based-route. It only affects traffic entering the specified interface.
Option D: Local PBR is configured in the protocol view.
Incorrect (False Statement).
Local PBR is not configured in the protocol view. It is typically configured using the command local-policy in the system view to handle traffic generated by the router.
3. Summary:
The answer: D (Local PBR is NOT configured in the protocol view).
Huawei HCIA-Datacom Study Guide, Chapter " Policy-Based Routing. "

NEW QUESTION # 223
Which of the following statements about stacked MAD detection is incorrect?

A. MAD proxy detection requires that all stack member proxy devices are connected and the connected links are added to an Eth-Tunk.
B. When stacking systems act as agents for each other for MAD detection, the two stacking systems can use the same Domain ID.
C. MAD direct connection detection can pass through the intermediate device and can adopt full-mesh method.
D. MAD detection methods are divided into direct connection detection and proxy detection.

Answer: B

NEW QUESTION # 224
KAD detection has two methods: direct connection detection and proxy detection. When the stack system is in the proxy detection mode, how often will the stack member switch that is running normally send MAD messages to detect the link?

A. 10 seconds
B. 20 seconds
C. 30 seconds
D. 1 second

Answer: B

NEW QUESTION # 225
Which of the following statements about stack split is false?

A. After a stack splits, multiple stacks have the same IP address and MAC address. To prevent network faults, the stacks perform MAD detection. The stack that fails the MAD detection shuts down all physical ports except reserved ports.
B. If the master and standby switches are in two stacks after the split, the stack where the original master switch resides updates the topology and selects a new standby switch. The original standby switch becomes the master switch in the new stack and a new standby switch is elected.
C. After a stack splits, the MAC addresses of the two stacks change immediately.
D. If the master and standby switches are still in the same stack after the stack splits, the slave switches separated from the original master and standby switches re-elect the master and standby switches due to protocol packet timeout.

Answer: C

Explanation:
When a stack splits, the MAC addresses of the newly formed stacks do not change immediately. Instead, they retain their original MAC addresses until new ones are reassigned during topology updates. This delayed update prevents immediate conflicts and allows MAD (Multiple Active Detection) to handle any resulting issues .

NEW QUESTION # 226
Which of the following statements regarding the BGP error display of a router is false?

A. The error may be caused by the incorrect peer AS number.
B. Error Type indicates that the BGP error is caused by the neighbor relationship error.
C. The neighbor address of this router is 10.1.1.2.
D. The error occurred at 11:40:39 on March 22, 2010.

Answer: D

Explanation:
The provided BGP error display shows the error timestamp as12:40:39 on March 22, 2010. The error message confirms a mismatch in the peer AS number, as indicated in the "Incorrect remote AS" error info. This eliminates options related to other causes, and the timestamp in Option A is incorrect .
