What is the minimum number 80 TB capacity nodes that must be added to the cluster to fulfill this requirement?

An administrator needs to protect a set of workloads across three sites (Site A, Site B, Site C) managed by different Prism Central instances. Which is the most efficient way to protect such VMs?

An administrator configures network segmentation and places the Data Services IP (DSIP) in a secondary non-routable subnet while the cluster is registered to Prism Central. Prism Central cannot initiate or complete cluster upgrades. How should the administrator resolve this issue?

The administrator expanded a Nutanix cluster repurposed nodes from a decommissioned cluster. The administrator has validated the following:
* Same number of cores, amount of memory and storage
* The nodes are on the same subnet
* The nodes are running the same version of AOS and AHV
After the nodes were added the administrator discovered that VMs cannot be migrated to the recently added nodes.
What would be the reason for this issue?

An administrator needs to ensure that if a host remains in a disconnected status for 40 seconds, VMs running on a host are automatically restarted.
What method should the administrator use to ensure root file system corruption has not occurred and that the root file system of a host isn't in a read-only state?
