You have a dual-processor virtual machine (VM) that has affinity set so that the virtual
CPUs are pinned to CPU 3 and 4 in VirtualCenter. The VM also has a reservation setting
guaranteeing it 100% of available resources for those two CPUs. Performance is poor in
this VM, however performance for all other VMs on this host is acceptable. What can
you do to improve performance for this VM?

A.
set CPU affinity on all other VMs prohibiting them from using CPU 3 and 4

B.
remove the reservations on the CPUs in order to allow the VMkernel to switch the
virtual CPUs between CPU 3 and 4 as needed

C.
change the CPU share allocation from ‘Normal’ to ‘High’

D.
change the CPU affinity settings to ensure that the virtual CPUs are running on two
separate physical CPUs on the host
