Which of the following are the most likely causes of the problem(Choose Two)?

DRS on a cluster with two ESX Hosts is set to Fully Automated mode. One server in the cluster is running at 98% CPU utilization, while the other host is running at 52% utilization.

Upon analysis, it appears that none of the virtual machines (VMs) are being migrated to the other server, and no recommendations are being generated. Which of the following are the most likely causes of the problem

(Choose Two)?

A.
The ESX Server has CPU features that are incompatible with other hosts in the cluster

B.
The VMotion licenses for the cluster have expired

C.
The current DRS Migration Threshold setting is too conservative

D.
Insufficient resources exist to perform the VMotion migration

Explanation:
A a posibilty
B- is not correct, there is no VMotion license
C- If you put threshold at 1, that is conservative, the DRS does not do any recommendation except for contraints like host in maintenance mode or anti-affinity rules, sounds logic to explain why no recommendations are being generated
D- RAM maybe unavailable, not just CPU

    I’d think that only C is correct. If A or D were correct recommendations would be generated and then (I’d expect) a warning or error would be generated. Does anybody have a lab to test?
