Which Nutanix solution would provide an organization with a Cloud DR capability for their Nutanix cluster?

An administrator has recently added two additional nodes to an existing three-node Nutanix cluster, which hosts critical business application VMs. The administrator will tolerate losing up to two nodes simultaneously within the cluster.
Which two actions are required to achieve this with minimum effort? (Choose two.)

Refer to the exhibit.

An administrator notices that the Data Resiliency Statue of some components has been reduced to 0. making it impossible to support a node failure in the cluster.
What type of failure is most likely the cause of this issue?

Which policy specifies that a selected VM will only run on a specific group of nodes?

A new Project is being rolled out to an AHV cluster being monitored by Prism Central. The applications team indicates that the application managed by the project is very memory intensive. The administrator wants to be notified about any memory constraints, should they occur.
How would an administrator most effectively achieve this task?
