How would you answer an interview scenario involving Hallucination management?

For an interview scenario involving Hallucination management, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Hallucination is when a model produces plausible-sounding content that is unsupported or incorrect. In this scenario, for an internal policy assistant, explain how you would make the model answer only from approved policies and say when evidence is insufficient. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
