Which of the following is true regarding DRS cluster with Intel and AMD based ESX/ESXi hosts? (Choose two)
A.
VMware DRS can load balance running virtual machines using all hosts in the cluster.
B.
VMware HA will failover virtual machines to any hosts in the cluster
C.
VMware FT can be configured for this cluster.
D.
VMware EVC can be enabled for this cluster.
A is wrong – You cannot vMotion VM between Intel and AMD CPUs (http://pubs.vmware.com/vsphere-50/topic/com.vmware.vsphere.vcenterhost.doc_50/GUID-03E7E5F9-06D9-463F-A64F-D4EC20DAF22E.html).
B is right – VM is powered-on during HA failover so the CPU vendor does not matter.
C is probably right – Secondary VM will be automatically placed on a host with the same CPU vendor and DRS load balancing is disabled for FT on non-EVC clusters.
D is wrong – All hosts in EVC-enabled cluster must have CPUs from a single vendor, either AMD or Intel. (http://pubs.vmware.com/vsphere-50/topic/com.vmware.vsphere.vcenterhost.doc_50/GUID-FEC87C0B-7276-4152-8EAA-915305E64FED.html)

C – vSphere Fault Tolerance can function in clusters with nonuniform hosts, but it works best in clusters with
compatible nodes.

You cannot pair Intel and AMD processors for FT virtual machines.

C & d are plain wrong. B is correct. A may be correct – as long as there are several hosts that have each type of processor.
