What does Distributed Power Management (DPM) do when workloads increase during peak times?
A.
Migrates virtual machines to hosts to balance power consumption.
B.
Brings powered-down hosts back online.
C.
Brings powered-down virtual machines back online.
D.
Adds additional resources to DPM-enabled clusters to handle the workload.
the answer correct is:
Brings powered-down hosts back online. DPM don’t power off VM

Agreed Marco. Says so in VMware documentation too. DPM MOVES vms but doesn’t power them down.

Yeap, DPM can only power off and on hosts not VM’s

Answer: B
VMware DPM is a function provided by DRS to reduce energy consumption during off peak times. When enabled, DPM monitors the environment for activity on the cluster and will consolidate VMs to as few ESXi hosts as are required to host the workloads and still satisfy availability constraints. After the workloads have been consolidated, DPM shut downs hosts into standby mode.
DPM automates and optimizes energy management in the datacenter, so that an administrator can cut the power costs during off peak times of resource utilization. When utilization increases, DPM automatically restarts the ESXi hosts that have been put into standby, thereby fulfilling the demand for resources.

Answer: B
Answer C does not make sense. VMs don’t consume power. Hardware does.

I think it does B and A (in that order as well).
When power consumption is low, DPM will aggregate VMs onto the minimum/optimal number of hosts required to satisfy the VMs power requirement. When workloads increase and power consumption increases, DPM will power on hosts that were in standby mode and start vMotioning VMs to these hosts in order to meet the increased power requirement.
