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

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.

    The wording of this question is ambiguous.
    IMHO it should read:
    “What does the value represent that is displayed for “recommended maximum memory for best performance” when configuring a virtual machine?”
    The wizard displays two maximum values:
    “Maximum recommended for best performance”
    and
    “Maximum recommended for this guest OS”.
    The question (as is) does not make it clear which one is referred to.
    From mthe explanation it can be seen that ‘best performance’ is meant.

    Dyslexia, you are completely correct. The question is ambiguous at best. When looking at the settings for memory on a VM there are two “Maximums” and each one uses the word “Recommended” in it.

    the # that I saw was like over 100 GB, does not relate to my host at all, nor has any thing to do with the VM that I am creating….
    So I have to choose D.
