Refer to the Exhibit. An administrator receives an error on a vSphere cluster as shown in the Exhibit. Based on the exhibit, which three configuration changes can resolve the error? (Choose three.)

Changing the Admission Control policy - for example, lowering the failover percentage or switching to a failover host policy - relaxes the resource thresholds that triggered the insufficiency error.

Reducing CPU and memory reservations on virtual machines decreases the slot size or reserved capacity that HA must account for, bringing the cluster back within the admission control policy limits.

Increasing available failover resources by adding hosts or removing VMs provides the physical resource headroom required by the configured HA failover level, directly resolving the error.

Reconfiguring ESXi hosts for HA does not resolve an admission control resource insufficiency; HA is already active and the error concerns available capacity, not HA enablement.

Virtual Machine Monitoring governs VM heartbeat-based restarts and has no bearing on admission control resource reservation calculations.
