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…

The correct answer is C. A reservation was set too high. All virtual machines require some memory to use as overhead to handle virtualization. Even if a virtual machine did not have a reservation, real memory would still be required for the overhead.
