An ArcGIS Online administrator can use the Content section to monitor which two types of usage information?

The focus of the Content section in ArcGIS Online is primarily on managing and monitoring content, which includes understanding how users interact with the shared items. Among the options provided, the correct answer pertaining to the usage information that can be monitored is indeed the number of members sharing items. This component of the administration tools allows the administrator to assess engagement with shared content among members in the organization.

By monitoring how many members are actively sharing items, administrators gain insights into collaboration, data dissemination, and content management within the organization. It reflects the level of participation in content sharing and can help highlight users who are heavily involved in the community or identify areas where engagement might be lacking.

The other options, while they relate to various aspects of ArcGIS Online administration, do not specifically pertain to the details about item sharing found in the Content section. The amount of credits consumed relates to billing, while knowing the number of members in each group and identifying top contributors pertain more to membership management and activity tracking rather than content sharing specifically.
