What are two requirements to enable EVC in vSphere DRS cluster? (Choose two.)
A.
CPUs must be from the same vendor.
B.
EVC must use the lowest possible baseline supported by the hardware.
C.
CPUs must be in the same family and of the same speed.
D.
No VMs may be running in the cluster.

In 6.5 it seems you only need to power off/vMotion all VMs “running on hosts with a feature set greater than the EVC mode that you intend to enable.”

That is correct, so the right answer should be AB
C is nonsense, that is what EVC is for
D is no true, because if the VM is compatible with the EVC mode, the VM can continue to run

I agree with A and B – B’s wording is a little off though.
Documents:
A – https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.vcenterhost.doc/GUID-FEC87C0B-7276-4152-8EAA-915305E64FED.html
“A single vendor, either AMD or Intel.”
B – https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.vcenterhost.doc/GUID-9F444D9B-44A0-4967-8C07-693C6B40278A.html
“The EVC mode must be equivalent to, or a subset of, the feature set of the host with the smallest feature set in the cluster”

Any one here already pass the exam ?

It’s AB but B is poorly formulated

why poorly formulated ? “EVC must use the lowest possible baseline supported by the hardware.” what are we talking about when talking EVC ? CPU’s. so replace “by the hardware” with “by the CPU’s”. for me it’s perfectly clear.
as for C, like being said it’s non-sense. and D, of course you can enable it only if you are enabling against all same CPU’s so you select the latest available EVC level for those CPU’s. Now if you have, let’s say a cluster with 3 old servers and 2 new servers, you cannot enable it on the baseline of the 3 old servers since the 2 new server are already joined to the cluster. What you do then is rather maintenance new host’s, remove from cluster, enable EVC on the old server’s baseline and then add new servers who will be “from base locked” into the selected EVC level. Voilà

The problem with B is that you don’t need to use the LOWEST level. In EVC you typically want to use the HIGHEST shared compatibility level, rather than the lowest otherwise you are crippling your CPU feature set to Intel® “Merom” Gen. (Intel® Xeon® Core™ 2) or AMD Opteron™ Generation 1. See https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003212

The answer does not say the lowest
It says the lowest supported by “all” Hardware “ESXI hosts”
Best answer is A,B
