Which ArcGIS Online capability allows for immediate updates to data presented in maps?

The correct choice emphasizes the functionality of real-time data sharing, which is essential in scenarios where immediate updates and responsiveness to changes are critical. This capability allows users to visualize and interact with data that is constantly being updated based on real-world events or conditions, ensuring that maps reflect the most current information available.

Real-time data sharing is particularly useful in applications like monitoring environmental changes, tracking assets, or providing up-to-date information in emergency management situations. As data changes in the source, these updates are automatically reflected in the maps, facilitating better decision-making and situational awareness.

In contrast, the other options do not offer the same immediacy. Scheduled backups refer to the regular archiving of data rather than live updating. Static data uploads involve uploading a dataset that remains unchanged until a new upload occurs, and while manual updates by users allow for changes, they can introduce delays and are not as efficient as automated real-time updates.
