What minimum number of clusters must be registered to Prism Central to open a support...

The correct answer isB. 1

Nutanix Prism Central provides the ability to create and manage support casesdirectly from the UI, but this functionality requiresat least one clusterto be registered to Prism Central. The Support option becomes active onceone or more clustersare managed.

Important distinctions:

Zero clusters(Option A): With no clusters registered, Prism Central is effectively disconnected from any environment and thus cannot associate logs or telemetry with a support case.

One cluster(Option B): Enables access to support features, including log bundle generation and direct case submission.

Options C and D (2 or 3 clusters) are incorrect; they arenot a requirementfor enabling support case functionality.

Prism Central UI Navigation Path:

Settings (gear icon) > Support > Create Support Case

Official Reference:

Nutanix Prism Central Guide – Support Integration Section

Excerpt: "To open a support case through Prism Central, ensure at least one cluster is registered. Support features become available once a cluster is connected."

Conclusion:Only one cluster is required to activate the support case workflow in Prism Central.
