Which of the following features cannot be altered for a Managed Source?

The correct answer indicates that deletion is the feature that cannot be altered for a Managed Source. In the context of a Managed Source, certain aspects such as creation, editing, and importing can typically be modified or configured to suit the needs of the organization or to adapt to changing requirements.

Managed Sources are intended to provide stability and consistency in how data is managed and accessed. By restricting the ability to delete these sources, the integrity and continuity of the data infrastructure are maintained, preventing accidental loss of important configurations or data sets that might impact overall system functionality. Thus, while you may create new sources, edit existing configurations, or import data, the deletion of a Managed Source is restricted to ensure the system remains reliable and secure.
