An Administrator notices that when a virtual machine is placed into a resource pool, a warning
indicates that the virtual machine would receive a very large percentage of the total shares for
memory.

Which of the following actions could be taken to resolve this problem?

A.
Change the Shares setting from custom to High, Medium or Low for the virtual machine

B.
Change the Shares setting from High to Medium or Low for the virtual machine

C.
Increase the memory resource allocation to the resource pool

D.
Increase the Share value for the resource pool

Explanation:
vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 157

The Memory Resources panel lets you allocate memory resources for a virtual machine and specify
reservations, limits, and shares. Symbolic values Low, Normal, High, and Custom are compared to the sum of all shares of all virtual machines on the server and, on an ESX host, the service console.

By decreasing the memory share of a particular system, it receives less memory out of the total available memory.
