In a vSphere 6.5 cluster, the administrator notices that it is possible to set a percentage in the DRS option, "Control CPU over-commitment in the cluster." Which is the purpose of this setting?
A. It sets and enforces a maximum percentage of virtual machine CPU usage in GHz in comparison to physical CPU availability in GHz.
B. It sets and enforces a maximum ratio in percentage between powered on virtual machine CPUs and available physical CPUs on hosts.
C. It prevents the creation of any additional virtual machines in the cluster.
D. It calculates the total shares assigned to all virtual machines in comparison to GHz of available physical CPU.
I just guessed it is B and im happy to see the others agree. It just made more sense to me at the moment.
B
and have peaceful dreams!

It’s the vCpu to pCpu ratio
