What function does Enhanced vMotion Compatibility (EVC) provide?
A. The ability to enable Fault Tolerance on virtual machines that are not members of a cluster.
B. The ability to use vMotion to migrate virtual machines between ESXi hosts with different CPU vendors.
C. The ability to replace manual CPU identification masks with an automated process managed by the cluster.
D. The ability to use vMotion to migrate virtual machines between hosts with identical CPUs but different vSphere versions.
Correct Answer: C
Explanation/Reference:
EVC is short for Enhanced vMotion Compatibility. EVC allows you to migrate virtual machines between different generations of CPUs.
Does EVC allow AMD and Intel CPUs to be vMotion compatible?
No. An EVC-enabled cluster only allows CPUs from a single vendor in the cluster. VirtualCenter and vCenter Server do not allow you to add a host from a different vendor into an EVC-enabled cluster.
The older masking feature involved applying manual masks to individual virtual machines. EVC takes effect on a whole cluster and all virtual machines in the cluster. More accurately, EVC affects the hosts themselves, making all the hosts in the cluster appear to be the same type of CPU hardware, even if they are different.
