What does the recommended maximum memory value that is displayed when configuring a virtual represent?

A.
The value that the operating system vendor reports as being optimal for performance

B.
The threshold needed for the ESXi host to satisfy a reservation value

C.
The maximum value the guest operating system supports

D.
The threshold above which the physical memory of the ESXi host is insufficient to run the virtual machine at full speed

Explanation:
The virtual machine settings editor also shows a value for the maximum amount of memory for best performance. If you have only one virtual machine running on the host and you set virtual machine memory to this value, the virtual machine can run entirely in RAM. A virtual machine running completely in RAM performs better than a virtual machine that must swap some of its memory to disk.
