Huawei H12-893_V1.0 Exam - Topic 5 Question 7 Discussion

Actual exam question for Huawei's H12-893_V1.0 exam

Question #: 7
Topic #: 5

M-LAG configuration consistency check classifies device configurations into key configurations (Type 1) and common configurations (Type 2). This check can be performed in strict or loose mode based on the processing mode when key configurations are inconsistent. Which of the following statements is false about M-LAG configuration consistency check?

AIn loose mode, if Type 1 configurations of the two M-LAG member devices are inconsistent, the member interface on the M-LAG backup device is in Error-Down state and an alarm is generated, indicating that Type 1 configurations on the two devices are inconsistent.

BIf Type 1 configurations of the two M-LAG member devices are inconsistent, certain problems may occur, such as loops and long-period packet loss when the status is normal.

CIf Type 2 configurations of the two M-LAG member devices are inconsistent, the M-LAG running status may be abnormal. Compared with Type 1 configuration problems, Type 2 configuration problems are more likely to be detected and have less impact on the network.

DIf Type 2 configurations of the two M-LAG member devices are inconsistent, an alarm that indicates key and common configuration inconsistencies is generated.

Show Suggested Answer

Suggested Answer: A, B, C, D

iMaster NCE-FabricInsight is Huawei's network assurance and analytics tool, integrated with CloudFabric, that uses telemetry to monitor network health. The health function identifies various issues. Let's evaluate each option:

A . Switch ARP entry threshold exceeded: This is true. FabricInsight monitors ARP table usage and can detect when the threshold is exceeded, indicating potential resource issues. TRUE.

B . OSPF router ID conflict: This is true. FabricInsight can detect OSPF router ID conflicts, which cause routing instability, through health checks on control plane data. TRUE.

C . Switch CPU usage threshold exceeded: This is true. FabricInsight tracks device performance metrics, including CPU usage, and flags thresholds to prevent performance degradation. TRUE.

D . Routing loop on the network: This is true. FabricInsight analyzes traffic patterns and routing tables to identify loops, leveraging telemetry data for network-wide health assessment. TRUE.

All options A, B, C, and D can be identified by the health function of iMaster NCE-FabricInsight.

I've seen loops happen from Type 1 inconsistencies, so that checks out.

I believe statement D is false because I don't think an alarm is generated for Type 2 inconsistencies; it’s usually just for Type 1.

For Type 2 configurations, I recall that they are less critical, but I'm uncertain if they really have less impact on the network compared to Type 1 issues.

I think I saw a practice question about how Type 1 inconsistencies can cause loops, so I feel like statement B might be true.

I remember studying the differences between Type 1 and Type 2 configurations, but I'm not sure if loose mode really puts the backup device in Error-Down state.

This question seems straightforward enough. I'll focus on understanding the differences between the options and identify the one that is clearly false based on the information provided. Careful reading is the key here.

I'm a bit confused by the terminology here. What exactly are Type 1 and Type 2 configurations? I'll need to make sure I understand the key concepts before I can confidently select the right answer.

Okay, I've got this. The false statement is option D. If the Type 2 configurations are inconsistent, an alarm is generated, not that the M-LAG running status may be abnormal. I'm confident I can get this one right.

Hmm, this seems a bit tricky. I'm not entirely sure about the differences between strict and loose mode, and how that impacts the behavior when the configurations are inconsistent. I'll need to re-read the question and options carefully.

Wait, so if the Type 2 configs are inconsistent, does that mean I can blame the network guy and not myself? Asking for a friend.
