解説:
Explanation
Terminology
* Availability Zone - it is represented by all resources (Nutanix Clusters) connected to Prism Central or Xi Leap Availability zone. Depends on the architecture, Availability zone can represent geographic territory, datacenter or server room in the datacenter. Protection policies - in protection policies you set up (RPO, Retention), rules to auto-apply policies to virtual machines
