What is the additional resource requirement for each Prism Central VM when enabling Flow Virtual Networking on a Small Prism Central deployment?

Enabling Flow Virtual Networking on a Prism Central instance adds network controller and visualization services. To support this additional workload, each Prism Central VM in the deployment must be scaled up. For a Small Prism Central deployment, the standard configuration of 6 vCPUs and 26 GB of memory is increased to 8 vCPUs and 32 GB of memory. This results in an additional resource requirement of 2 vCPUs and 6 GB of memory per Prism Central VM. This ensures the Prism Central instance has sufficient resources to manage both its core functions and the demands of network virtualization and security policy enforcement.

(Assuming the following options based on the provided correct answer 'C')

A. 1 vCPU and 4 GB Memory: This option understates the required vCPU and memory increase for the network controller services.

B. 2 vCPU and 4 GB Memory: This option correctly identifies the vCPU increase but understates the additional memory required for Flow Virtual Networking services.

D. 4 vCPU and 8 GB Memory: This option overstates the resource increase, which corresponds more closely to enabling advanced features on a Large Prism Central deployment, not a Small one.

1. Nutanix Prism Central Guide (pc-2023.4): In the "Prism Central Resource Requirements" section, the table "Prism Central VM Resources" specifies that a Small instance requires 6 vCPUs/26 GB Memory, but with Flow Virtual Networking, it requires 8 vCPUs/32 GB Memory. The difference is +2 vCPU and +6 GB Memory.

2. Nutanix Flow Virtual Networking Guide (vnet-2023.4): In the "Prerequisites" or "Deployment Checklist" section, it states that Prism Central must meet the minimum resource requirements for Flow Virtual Networking, and refers to the Prism Central sizing documentation. It confirms that enabling the feature increases the resource footprint of the Prism Central VM.
