Which two statements are true regarding a mixed DRS cluster with Intel Intel-Based and AMD- based ESXi hosts? (Choose two)
A.
DRS can load-balance running virtual machines, using all hosts in the cluster
B.
HA can failover virtual machines to any host in the cluster
C.
FT can be configured for this cluster
D.
EVC can be enabled for this cluster
Explanation:
A: Wrong, you cannot vMotion VM between Intel and AMD CPUs
B: Right, VM is powered-on during HA failover so the CPU vendor does not matter.
C: 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: Wrong, All hosts in EVC-enabled cluster must have CPUs from a single vendor, either AMD or Intel.Source:

C. cannot be right!!!…. FT cannot work in mixed intel / Amd environments

C. is wrong or There must be a mistake in the options provided
Here it clearly states that vSphere FT does not support cross compatibility between Intel and AMD processors. You cannot pair Intel and AMD processors for FT virtual machines.

C is correct, assuming multiple hosts per CPU family.
