An administrator has a mixture of Intel-based ESX Hosts in a DRS cluster where the CPUs are compatible in
every way except that some support the NX/XD feature and some do not. Which two actions will minimize the effect of these differences? (Choose two.)
A.
Mask the NX/XD bit in the Processor section of the Configuration tab on the ESXi hosts
B.
Mask the NX/XD bit on every virtual machine in the cluster
C.
Enable Enhanced VMotion Compatibility
D.
Enable Rapid Virtualization Indexing

To modify the mask to enable or disable the NX/XD CPU bit:
Navigate to the CPUID Mask option on the virtual machine Options tab (see steps above, if necessary).
Select Hide the NX flag from guest to disable the CPUcompatibility check for the selected virtual machine,or Expose the NX flag to guest to enable this CPU compatibility check for the selected virtual machine.
Click OK to save the change.
