How can a vSphere administrator ensure that a set of virtual machines run on different hosts in a DRS cluster?
Use a VM-Host affinity rule.
Add the VMs to a vApp.
Use a VM-VM affinity rule.
Place the VMs in different folders.
A VM-VM affinity rule specifies whether selected individual virtual machines should run on the same host or be
kept on separate hosts. This type of rule is used to create affinity or anti-affinity between individual virtual
machines that you select.
