Which of the following can be deployed to enhance DC reliability?

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 Denhance DC reliability.References:Huawei CloudFabric Data Center Network Solution – Reliability Features; HCIP-Data Center Network Training – High Availability.
