- A
Amazon Macie
Correct. Amazon Macie is designed to automatically discover, classify, and protect sensitive data in Amazon S3, including PHI, using machine learning. It requires no manual scanning and integrates with AWS Security Hub for alerting.
- B
Amazon Inspector
Why wrong: Incorrect. Amazon Inspector is a vulnerability management service that scans Amazon EC2 instances and container images for software vulnerabilities and unintended network exposure. It does not scan S3 data content for sensitive information.
- C
AWS Config
Why wrong: Incorrect. AWS Config is a service that evaluates and records the configuration of AWS resources, such as whether an S3 bucket is publicly accessible. It does not analyze the contents of S3 objects for sensitive data like PHI.
- D
AWS Security Hub
Why wrong: Incorrect. AWS Security Hub provides a centralized view of security alerts and compliance status across multiple AWS accounts. It can aggregate findings from Amazon Macie, but by itself it does not discover sensitive data in S3.
Quick Answer
The answer is Amazon Macie, the fully managed AWS service designed to automatically detect protected health information in S3 buckets. Macie uses machine learning and pattern matching to discover and classify sensitive data like medical record numbers, diagnosis codes, and patient names, then generates alerts—all without any manual scanning effort, making it ideal for HIPAA compliance. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of managed security services versus manual or third-party tools; a common trap is confusing Macie with Amazon GuardDuty (which focuses on threat detection) or AWS Config (which tracks resource configuration). Remember that Macie is your go-to for data classification and privacy, not for infrastructure monitoring. A simple memory tip: Macie “minds” your data’s privacy, so think “Macie for medical.”
CLF-C02 Security and Compliance Practice Question
This CLF-C02 practice question tests your understanding of security and compliance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A healthcare company is migrating patient records to Amazon S3. The company must comply with HIPAA and needs to automatically identify any S3 buckets that contain protected health information (PHI) and generate alerts. The solution must be fully managed and require no manual effort to scan the data. Which AWS service should the company use?

Correct answer & explanation
Amazon Macie
Amazon Macie is a fully managed data security and data privacy service that uses machine learning and pattern matching to discover, classify, and protect sensitive data in Amazon S3. It automatically identifies protected health information (PHI) such as medical record numbers, diagnosis codes, and patient names, and can generate alerts when such data is found in S3 buckets, meeting HIPAA compliance requirements without any manual scanning effort.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Incorrect. AWS Security Hub provides a centralized view of security alerts and compliance status across multiple AWS accounts. It can aggregate findings from Amazon Macie, but by itself it does not discover sensitive data in S3.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Amazon Inspector (which sounds like it 'inspects' data) with Macie, but Inspector only scans for vulnerabilities in compute resources, not for sensitive data content in S3 objects.
Detailed technical explanation
How to think about this question
Amazon Macie uses a combination of machine learning models and managed data identifiers (e.g., regex patterns for US Social Security numbers, HIPAA-specific identifiers like ICD-10 codes) to automatically discover and classify sensitive data. It can be configured to run continuous, automated sensitive data discovery jobs against S3 buckets, and when PHI is detected, it generates findings that can be sent to Amazon EventBridge, AWS Security Hub, or Amazon SNS for alerting and remediation workflows.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
