An organisation needs to ensure that all conversation logs in watsonx Assistant are retained for no more than 30 days to comply with a GDPR data-minimisation requirement. Where should the administrator configure this retention period?

watsonx Assistant provides a Privacy settings section at the service-instance level where administrators can configure how long conversation logs are retained before automatic deletion. Setting this to 30 days satisfies a data-minimisation requirement without requiring a support ticket or relying on non-existent compliance-mode toggles. The Analytics panel displays data but does not control retention policy. The correct answer, "Under Privacy settings in the watsonx Assistant service instance configuration, set the log retention period to 30 days", directly satisfies the scenario because it aligns with watsonx Assistant's design principles and the specific capability being tested. The incorrect options ("In the assistant's Analytics settings, set the log retention slider to 30 days", "Submit an IBM Cloud support ticket requesting a custom data-retention policy for the service instance", "Enable the built-in GDPR compliance mode toggle in the Integrations panel to automatically purge logs after 30 days") may appear relevant but each misses a key requirement or introduces a step that is either unnecessary or belongs to a different workflow. Mastering the distinction between these approaches is essential for effective watsonx Assistant implementations and is a core focus of the Domain 5: Administration section of the certification exam.
