Which is the default port for ArcGIS Data Store?

The default port for ArcGIS Data Store is 6443. This port is used for secure communication. The reason this is the correct choice is that ArcGIS Data Store operates as a secure service that requires standardized communication protocols. Port 6443 is designated for HTTPS traffic that ensures the data is transmitted securely between the Data Store and the ArcGIS Server.

Other options signify different purposes; for instance, port 6080 is typically used for the ArcGIS Server web services. Ports like 2443 and 7080 are not standard assignments associated with ArcGIS Data Store or generally recognized services within the ArcGIS ecosystem. Awareness of these designated ports helps in proper configuration and troubleshooting when setting up Communicationally reliant components within the Esri platform.
