Which statement is true regarding the update process for Read-Only custom fields?

The statement regarding the update process for Read-Only custom fields that is true is that Read-Only custom fields can only be updated by a data feed. This means that these fields are designed to prevent manual edits from standard users, ensuring that the data remains consistent and reliable.

The reasoning behind this is that Read-Only custom fields are typically used to hold important information that should not be altered by any user actions, except through a defined and controlled process such as a data feed. Data feeds can automate the entry of data from external sources, ensuring that the information is updated without manual intervention.

The other options suggest that updates can be made through various means such as user roles, specific administrators, or IT technicians, but these do not apply to Read-Only custom fields as they are specifically designed to restrict modifications to safeguard data integrity. This characteristic reinforces the idea that Read-Only fields should maintain their state unless they are programmatically updated through a secure and methodical approach like a data feed.
