A cloud administrator is tasked with configuring a group of VMs that handle sensitive data processing. These VMs must be isolated due to compliance requirements and should not share hardware resources with other VMs processing less sensitive data. To maintain compliance, which type of affinity rule should the administrator implement?
The correct answer is 'VM-Host Affinity'. This rule will ensure that the VMs processing sensitive data are bound to a particular subset of hosts that are dedicated for this purpose and do not run on the same physical hosts as VMs handling less sensitive data. 'VM-VM Anti-Affinity', though close, is incorrect because it would only prevent the VMs from residing on the same host but doesn't prevent them from sharing the host with other non-related VMs. 'Host-Host Affinity' is not a legitimate rule in the context of VM placement strategies. 'VM-Host Anti-Affinity' is also incorrect, as this would prevent the sensitive VMs from running on the specified hosts, the opposite of the requirement.
