Which statement is TRUE about Read-Only custom fields?

Read-Only custom fields are designed to ensure that the data they contain cannot be modified directly through the user interface by end-users. This feature is particularly useful for maintaining the integrity of critical data and ensuring that specific information remains consistent and accurate over time.

The only way to update these fields is through a data feed, which is a system or automated process that imports or updates information in bulk. This allows for controlled updates while minimizing the risk of user errors or unauthorized modifications.

The other statements do not accurately represent how Read-Only custom fields function within the system. For instance, they cannot be updated by any user, nor can they be changed through the user interface, and there is no requirement for them to be filled out during the initial user creation unless predetermined by system design. Thus, the correct answer emphasizes the specific mechanism by which these fields can be updated, reinforcing the controlled nature of their data management.
