Which two conditions could prevent HA from powering on a virtual machine? (Choose two.)
A. An ESXi host has been placed into maintenance mode.
B. The virtual machine has been assigned a required affinity rule.
C. Strict admission control is configured.
D. The vCenter is hosted on the ESXi host that failed.
Correct Answer: AC
Explanation/Reference:
Admission control imposes constraints on resource usage and any action that would violate these constraints is not permitted. Examples of actions that could be disallowed include:
Powering on a virtual machine.
Migrating a virtual machine onto a host or into a cluster or resource pool.
Increasing the CPU or memory reservation of a virtual machine.
Affinity rules are used by DRS.
There’s another variation on this question that has "The VM has a low priority setting" instead of "An ESXi host has been placed into maintenance mode."
