When using DPM in a vSphere HA cluster with Admission Control enabled, which two statements are true? (Choose two.)
The correct answer is B. If necessary, DPM powers on hosts from standby mode to maintain failover needs. E. DPM does not place hosts in standby mode if doing so would violate failover requirements.. DPM integrates with vSphere HA Admission Control by respecting failover capacity requirements - it will not consolidate workloads onto fewer hosts if doing so would reduce failover capacity below the configured threshold, and it will power hosts back on if failover capacity drops
Question
When using DPM in a vSphere HA cluster with Admission Control enabled, which two statements are true? (Choose two.)
Options
- ADPM can not be enabled on a cluster with HA Admission control enabled.
- BIf necessary, DPM powers on hosts from standby mode to maintain failover needs.
- CEVC must be enabled on the cluster before DPM can be enabled.
- DDPM and HA do not interact with each other. There will be no change in behavior when DPM is
- EDPM does not place hosts in standby mode if doing so would violate failover requirements.

Why each option
DPM integrates with vSphere HA Admission Control by respecting failover capacity requirements - it will not consolidate workloads onto fewer hosts if doing so would reduce failover capacity below the configured threshold, and it will power hosts back on if failover capacity drops.
DPM can be enabled alongside HA Admission Control - the two features are designed to coexist, with DPM deferring to Admission Control constraints rather than being blocked entirely.
When HA Admission Control is enabled, DPM actively monitors cluster failover capacity. If powering off hosts causes available failover capacity to fall below the configured threshold, DPM will power standby hosts back on to restore the required failover headroom. This ensures HA failover guarantees are maintained even as DPM tries to consolidate workloads.
EVC (Enhanced vMotion Compatibility) is a CPU compatibility feature for vMotion and is not a prerequisite for enabling DPM on a cluster.
DPM and HA interact directly - DPM reads Admission Control failover requirements and adjusts its host standby decisions accordingly, so behavior does change when both are active.
DPM evaluates HA Admission Control policy before placing any host into standby. If evacuating a host would violate the configured failover capacity (slot-based, percentage, or dedicated host policies), DPM will skip that host entirely, preventing it from entering standby mode.
