How many members can be configured with the administrator role in an Enterprise portal?

The correct answer to the question on how many members can be configured with the administrator role in an Enterprise portal is that it can be unlimited. In ArcGIS Enterprise, the administrator role is designed to give users full control over the portal, allowing them to manage users, create and delete content, and configure settings.

Having an unlimited number of administrators provides organizations with the flexibility to assign multiple individuals to this critical role. This can be beneficial for larger organizations where management tasks may need to be shared among several people to ensure effective and timely operations. It also allows for redundancy, meaning that if one administrator is unavailable, the responsibilities can be handled by others without interruption.

In contrast, the other answer choices suggest limitations that do not reflect the capabilities of the ArcGIS Enterprise system. Organizations may have unique needs and structures that require multiple administrators to effectively support their users and resources, so the architecture of the system is designed to accommodate that requirement.
