2V0-622D · Question #186
What are two requirements to enable EVC in a vSphere DRS cluster? (Choose two.)
The correct answer is A. CPUs must be from the same vendor. D. EVC must use the lowest possible baseline supported by the hardware.. EVC requires CPUs from the same vendor and automatically sets the cluster feature baseline to the lowest CPU capability present among all hosts.
Question
What are two requirements to enable EVC in a vSphere DRS cluster? (Choose two.)
Options
- ACPUs must be from the same vendor.
- BCPUs must be in the same family and of the same speed.
- CNo VMs may be running in the cluster.
- DEVC must use the lowest possible baseline supported by the hardware.

Why each option
EVC requires CPUs from the same vendor and automatically sets the cluster feature baseline to the lowest CPU capability present among all hosts.
EVC baselines are vendor-specific - Intel and AMD use entirely different CPU feature masking schemes, so mixing vendors in one EVC cluster is technically impossible and unsupported.
CPUs do not need to be the same family or speed - EVC is designed specifically to handle generational differences within a vendor by masking newer CPU features down to a common baseline.
Running VMs do not block EVC from being enabled on a cluster; only VMs whose current CPU feature usage exceeds the new baseline must be powered off and restarted to adopt the masked feature set.
EVC enforces a single cluster-wide CPU feature mask determined by the least capable CPU in the cluster, ensuring every host can present an identical feature set to VMs for safe vMotion migrations.
