From where does ArcGIS Data Store obtain its license?

ArcGIS Data Store obtains its license from the registered ArcGIS Server. This relationship is essential for the operation of the Data Store, as it must be associated with a particular ArcGIS Server site to function correctly. When you register the Data Store with an ArcGIS Server, it establishes a link that allows the Data Store to manage its resources in a way that is compatible and aligned with the configurations and capabilities of the server.

This licensing structure allows for seamless integration and management of data, enabling the Data Store to serve a variety of functions, such as hosting data for web layers and backing up the server's primary data. This ensures that the services running on the ArcGIS Server can effectively utilize the data managed by the Data Store, thus facilitating the overall architecture of an ArcGIS Enterprise deployment.

In contrast, the other choices do not accurately represent how ArcGIS Data Store acquires its license. ArcGIS Online does not provide licensing for local server setups like ArcGIS Server, and local machine licenses or a master license server don't apply in this context. The Data Store's licensing is intrinsically woven into the framework of the registered ArcGIS Server, establishing a coherent environment for data management and service distribution.
