Exam NCP-MCI-7.5 Topic 1 Question 27 Discussion

Nutanix documentation for Prism Central deployment states that single Prism Central VM deployments are supported in Small, Large, or X-Large sizes, and that a single-VM deployment can later be scaled out. Since X-Small is not the supported minimum deployment size in this documented model, the minimum supported size is Small. That makes A correct.
This question is really checking whether the administrator understands the starting point for a scale-out- capable Prism Central design. The existence of larger sizes does not change the minimum supported entry point. Nutanix's documentation is explicit that a single Prism Central VM can begin at Small and later be expanded if more scale or resiliency is needed. Therefore, for a single-node Prism Central deployment with future scale-out potential, the correct answer is Small.
