What is the size of a Virtual Machine .vswp file if defaults are taken for the VM reservations, limits, and shares?

A.
The VM .vswp file is equal to the amount of virtual memory (VM available memory
plus VM overhead)
configured for the VM when it was created

B.
The VM .vswp file is set to zero length when the VM is created and grows as
necessary

C.
The VM .vswp file is equal to twice the amount of available memory configured for
the VM when it was created

D.
The VM .vswp file is equal to the amount of available memory configured for the VM
when it was created

Explanation:
The default VM reservations, limits, and shares are shown below.
Determining the right size for your VMware VMFS data stores.
The .vswp fileis a virtual swap file that equals the size of the memory assigned to a VM,
minus any memory reservations assigned to a VM, which by default is zero.
