A new ESXi host is set up with two virtual machines. A memory limit is applied so that users will
have predictable performance as additional VMs are added to the host. Which of the following
describes the effect of applying a memory limit to these VMs?

A.
Physical memory will be granted above the limit under normal conditions, disk pages will be
used if contention occurs.

B.
Memory will be granted above the limit under normal conditions, but the limit will be enforced if
contention occurs.

C.
No memory will be granted above the limit.

D.
No physical memory will be granted above the limit, but disk pages may be used.

Explanation:
Shares Specify the relative priority for a virtual machine if more than the reservation is available.
Reservation Is a guaranteed lower bound on the amount of physical memory that the host reserves for the virtual machine, even when memory is overcommitted. Set the
reservation to a level that ensures the virtual machine has sufficient memory to run efficiently, without excessive paging.

After a virtual machine has accessed its full reservation, it is allowed to retain that amount of memory and this memory is not reclaimed, even if the virtual
machine becomes idle. For example, some guest operating systems (for example, Linux) might not access all of the configured memory immediately
after booting. Until the virtual machines accesses its full reservation, VMkernel can allocate any unused portion of its reservation to other virtual machines.
However, after the guests workload increases and it consumes its full reservation, it is allowed to keep this memory.

Limit Is an upper bound on the amount of physical memory that the host can allocate to the virtual machine. The virtual machines memory allocation is also
implicitly limited by its configured size. Overhead memory includes space reserved for the virtual machine frame buffer and various virtualization data structures.
