A GIS administrator is setting up a distributed collaboration between an ArcGIS Online organization and an ArcGIS Enterprise organization for a data validation project. Users from a second ArcGIS Online org will also participate. What should the administrator set up?

A single distributed collaboration is limited to having only one ArcGIS Online organization as a participant. To connect an ArcGIS Enterprise organization with two separate ArcGIS Online organizations, the administrator must configure two distinct collaborations. The ArcGIS Enterprise portal will participate in both collaborations, establishing one connection with the first ArcGIS Online organization and a second, separate connection with the other. This architecture is the only supported method to achieve the required data synchronization between all three organizations for the project.

B. Adding users from the second organization to a group does not establish the automated, bi-directional content synchronization that is the core function of a distributed collaboration.
C. A single distributed collaboration cannot include more than one ArcGIS Online organization. This is a fundamental architectural limitation of the technology.
D. Public access is a general sharing mechanism, not a distributed collaboration. It lacks the security, control, and automated synchronization features required for a structured project.

1. Esri ArcGIS Enterprise Documentation. Key concepts for collaboration. Under the section "Participants in a collaboration," it states, "A collaboration can include multiple ArcGIS Enterprise participants but only one ArcGIS Online organization." This directly refutes option C and supports the need for multiple collaborations as described in option A.

2. Esri ArcGIS Enterprise Documentation. Common questions about distributed collaboration. This page addresses the scenario directly in the "Collaboration participants" section. The question "Can I collaborate with more than one ArcGIS Online organization?" is answered with "No. A collaboration is limited to one ArcGIS Online organization." This confirms that option C is invalid.

3. Esri ArcGIS Enterprise Documentation. An overview of distributed collaboration. The overview describes the purpose of collaboration as establishing a trusted environment for content synchronization. This contrasts with simply adding users to a group (Option B) or making data public (Option D), which do not provide the same level of integration and control.
