A GIS analyst publishes a 3D scene from ArcGIS Pro to ArcGIS Enterprise to create a hosted 3D scene layer. Which data store hosts the data for the 3D…

When a 3D scene is published from ArcGIS Pro to ArcGIS Enterprise as a hosted scene layer, the data is stored in the tile cache data store. This data store is specifically configured to manage the caches for hosted scene layers and tile layers. Scene layers are pre-generated caches (in the I3S/SLPK format) optimized for fast visualization of large 3D datasets over the web. The tile cache data store provides a highly scalable, file-based storage solution required for these caches.

B. Relational: The relational data store is used for storing the data of hosted feature layers, not the caches for scene layers.

C. Raster: Raster is a data format, not a type of ArcGIS Data Store. While raster data can be published as a tile layer, its cache is stored in the tile cache data store.

clarifying that the tile cache data store is for scene layer caches.
