Your company is very cyclical in nature, with periods of very high demand and periods of very low
demand. You’ve heard that Distributed Power Management (DPM) may be helpful in saving
money. What function does DPM perform?
A.
Suspends idle VMs.
B.
Moves VMs onto fewer servers during periods of low demand, shutting the others off and
waking them up when load increases.
C.
Reduces or raises clock speeds of the CPU to optimize energy usage.
D.
Reduces or raises clock speeds of memory to optimize energy usage.

I would have to say the Answer should be A —- When you enable DPM, it compares cluster- and host-level capacity to virtual machine demand, including recent historical demand, and places hosts in standby mode – See more at:

I believe the correct answer is B because DPM does not suspend VM’s, using vMotion it will move them to other hosts in the cluster and using BMC/Wake-on-lan shut the server down and power it back up when needed again.
