required affinity rule

Explanation:

To determine the rule for ensuring two VMs are always on different physical machines, we analyze each option:

• Required anti - affinity rule: Mandates that VMs must be on different physical machines. This fits the requirement.
• Preferred anti - affinity rule: Suggests placing VMs apart but doesn't enforce it. Eliminate.
• Required affinity rule: Mandates VMs be on the same machine. Eliminate.
