Question 155 [Manage Nutanix clusters]

Which Nutanix feature allows administrators to expand a cluster by adding new nodes without downtime?

A. AHV Protection Domains

B. Prism Central

C. Scale-out Architecture

D. Metro Availability

Answer: C

VM templates in Nutanix are supported only when the VM’s disks reside on storage containers configured with Replication Factor 2 (RF2) or higher.

Option C (VM has disks on RF2 containers) is correct:

VM templates requirea minimum RF2 for fault tolerance.

RF1 containers do not meet Nutanix best practices for VM templates.

Option A is incorrect:

VMs protected by Protection Domains can be cloned, but this is different from creating a VM template.

Option B is incorrect:

Agent VMs (e.g., Witness VMs) or Prism Central cannot be used as VM templates.

Option D is incorrect:

Nutanix VM templates are natively supported on AHV, not ESXi.

The most efficient way to move a VM’s storage to a container that has different storage optimization policies (like compression) is to perform aVM migrationto the target container. This operation ensures that all the VM’s vDisks are moved to the destination container and allows leveraging the configured optimizations on the Production container.

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“VM migration to another storage container in Nutanix Prism Central is supported and can be performed with minimal disruption. When moving a VM to a new container, it inherits the storage optimization policies of that container, including compression, deduplication, and encryption.”

Furthermore:

“Migrations can be initiated at the VM level in Prism Central or Prism Element. This is the most streamlined method to ensure all vDisks for a VM are moved together, preserving data integrity and performance characteristics.”

Recreating the VM or vDisks would be cumbersome and require manual data copying, introducing potential risks and downtime.
