An application will call Amazon Q Business APIs to produce product recommendations, and the company must ensure responses never include the name of its main competitor. Which configuration enforces this?

Adding the competitor's name as a blocked phrase in Amazon Q Business directly prevents the model from generating that specific phrase in its responses, ensuring compliance with the requirement. Configuring the retriever to exclude the name from retrieved content might not prevent the model from generating the name if it's part of its learned knowledge. Using an Amazon Kendra retriever and omitting the name in indexes would prevent retrieval but not necessarily generation. Document attribute boosting would only deprioritize results, not guarantee exclusion from the generated response.
