Huawei Exam H12-893_V1.0 Topic 4 Question 8 Discussion

Reliability in Huawei's CloudFabric data centers is enhanced through various mechanisms. Let's evaluate each option:

A . Power supply redundancy: This is true. Redundant power supplies (e.g., dual PSUs) ensure uninterrupted operation during power failures, a key reliability feature. TRUE.

B . M-LAG (Multi-Chassis Link Aggregation): This is true. M-LAG provides high availability by allowing active-active forwarding and failover between switches, enhancing network reliability. TRUE.

C . Monitor Link: This is false. Monitor Link is a Huawei feature for link status monitoring, not a direct reliability enhancement mechanism like redundancy or clustering. FALSE.

D . Controller cluster: This is true. A clustered SDN controller (e.g., iMaster NCE-Fabric) ensures high availability and failover, improving network management reliability. TRUE.

Thus, A, B, and D enhance DC reliability.
