What is preventing the virtual machine from powering on?

While viewing the ESXi host resource tab, you notice that you have 1 GB of available memory.
You attempt to turn on a virtual machine with a 1 GB reservation, and the virtual machine will not
power on. What is preventing the virtual machine from powering on?

A.
There are too many virtual machines on the host.

B.
For a virtual machine to start, there must be enough available memory for the reservation and
memoryoverhead.

C.
A reservation was set too high.

D.
A CPU reservation was not set.

Explanation:

All virtual machines require some memory to use as overhead to handle virtualization. Even if
avirtual machine did not have a reservation, real memory would still be required for the overhead.
