What function does Enhanced vMotion Compatibility provide?
A.
The ability to use vMotion to migrate virtual machines between ESXi hosts that have CPUs with hardware virtualization capabilities and CPUs without this feature.
B.
The ability to use vMotion to migrate virtual machines between ESXi hosts that have CPUs with a sommon supported baseline.
C.
The ability to use vMotion to migrate virtual machines between ESXi hosts with intel CPUs and ESXi hosts with AMD CPUs.
D.
The ability to use vMotion to migrate virtual machines between ESXi hosts with different core counts.

enhanced VMotion Compatibility (EVC) simplifies VMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers. After EVC is enabled for a cluster in the VirtualCenter inventory, all hosts in that cluster are configured to present identical CPU features and ensure CPU compatibility for VMotion. The features presented by each host are determined by selecting a predefined EVC baseline. VirtualCenter does not permit the addition of hosts that cannot be automatically configured to be compatible with the EVC baseline.
EVC does not allow for migration with VMotion between Intel and AMD processors. I would chose B for this certainly not C
the answer should be B. btw you posted the same question but in different answer

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.

VCP5 book (Brian Atkinson) states on page 456 that “All hosts in the cluster must have only Intel or only AMD processors”. Therefore answer B is correct.
