The architect documented a requirement for 99.

To achieve 99.95% availability in the management domain, the architecture must protect critical management components (like vCenter) and ensure rapid recovery:

A. vCenter HA – Protects the vCenter Server by providing an active-passive-failure detection architecture, ensuring no single vCenter outage impacts operations.

D. Restart priority policy = High – Ensures vCenter recovers first and fastest during a host failure, minimizing downtime.

Why not the others?

B/E (EtherChannel Enable/Disable) – Link aggregation is networking config, not directly tied to SLA.

C (das.iostatsinterval = 0) – This disables HA datastore heartbeating, reducing resiliency rather than improving it.
