When operating with Distributed Resource Scheduler (DRS) and Distributed Power Management (DPM), what two statements explain the impact of disabling vSphere High Availability admission control?…

Question

Options

• ADRS will evacuate virtual machines from hosts and places in maintenance or standby modes
• BVmware DPM will place hosts in standby mode even if doing so violates failover requirements.
• CDRS does not evacuate virtual machines from a host for the purpose of placing it in maintenance
• DVMware DPM does not place hosts in standby mode if doing so would violate failover

• A
  54% (13)
• C
  17% (4)
• D

Explanation

When you disable VMware HA strict admission control, virtual machines can be powered on even if there are not sufficient resources to ensure failover capacity. When this is done, no warnings are presented, and the cluster does not turn red. When strict admission control is disabled, VMware HA failover resource constraints are not passed on to DRS and VMware DPM. Thus, the constraints are not enforced: DRS does evacuate virtual machines from hosts and place the hosts in maintenance mode or standby mode regardless of the impact this might have on failover requirements. VMware DPM does power off hosts (place them in standby mode) even if doing so violates failover requirements. https://kb.vmware.com/s/article/1007006?language=en_US
