A healthcare organization plans to modernize an on-premises information system and use generative AI to answer patients' medical questions. Which AWS offering should they use to help ensure responsible AI behavior for the application?

Guardrails for Amazon Bedrock is the correct choice because it is specifically designed to implement responsible AI policies for generative AI applications. It allows organizations to define custom policies to detect and prevent the generation of harmful, off-topic, or inappropriate content, which is crucial for a healthcare application answering patient questions. Amazon Inspector is a security assessment service that identifies vulnerabilities in applications and infrastructure, not generative AI content. Amazon Rekognition is a computer vision service for image and video analysis, unrelated to generative AI text output. AWS Trusted Advisor provides recommendations for cost optimization, security, performance, and fault tolerance, but does not directly manage generative AI content safety.
