AIF-C01 Applications of Foundation Models Practice Question
A healthcare company uses Amazon Bedrock to generate patient summaries. They need to ensure no protected health information (PHI) is leaked in the output. Which AWS service can they use to detect and mask PHI in text?
⚠ Common exam trap
AWS often tests the distinction between general-purpose data protection services (like Macie) and domain-specific medical NLP services (like Comprehend Medical), leading candidates to choose Macie because it is associated with sensitive data discovery, even though it cannot perform inline text masking.

Correct answer & explanation
✓
Amazon Comprehend Medical
Amazon Comprehend Medical is specifically designed to extract and identify protected health information (PHI) from unstructured medical text using natural language processing (NLP). It can detect entities such as patient names, dates, medical conditions, and medications, and provides APIs to mask or redact that PHI before output. This makes it the correct choice for the healthcare company's requirement to prevent PHI leakage in patient summaries generated by Amazon Bedrock.
