What controls data access at the authentication level within Analytics?

The correct choice is based on the role that integration user access to fields and objects plays in controlling data access at the authentication level within Analytics. This involves managing which users can access specific data features based on their authentication credentials.

Integration users typically have defined permissions that allow them to interact with data objects and fields in a controlled manner, effectively determining what data a user can see and manipulate once they are authenticated and logged in. This ensures that sensitive information is protected and that data access aligns with the organizational policies regarding user roles and responsibilities.

The other options, while they may involve aspects of data management and security, do not specifically address data access control at the authentication level in the way that integration user access does. For instance, user interface settings relate more to the visual aspects of the application rather than data access restrictions, data masking settings are focused on obscuring sensitive data rather than controlling access, and role-based permissions, while relevant, do not capture the direct connection to integration user access in the context of authentication.
