The standard feature analysis tools in ArcGIS Enterprise (e.g., buffer, overlay, aggregate points) require hosted feature layers, which depend on the relational data store (a component of ArcGIS Data Store). The relational data store is the default location for hosting feature layers.

From ArcGIS Enterprise documentation:

“To use the standard spatial analysis tools and create hosted feature layers, the ArcGIS Data Store (relational) must be configured and set as the default hosting location.”

Option A (spatiotemporal big data store) is used for real-time and big data feeds, not standard analysis.

Option C supports cached tiles, not feature layers.
