- 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.
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.

Amazon Macie
Why this is correct
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.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Amazon Inspector
Why it's wrong here
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.
When this WOULD be correct
An exam question asking which AWS service can automatically assess EC2 instances for software vulnerabilities and unintended network exposure, with no manual scanning required.
- ✗
AWS Config
Why it's wrong here
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.
When this WOULD be correct
A company needs to continuously monitor and record changes to S3 bucket policies and ensure they comply with a custom rule (e.g., requiring encryption or blocking public access). AWS Config would be the correct service to track configuration changes and trigger alerts for non-compliant resources.
- ✗
AWS Security Hub
Why it's wrong here
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.
When this WOULD be correct
A company wants a single pane of glass to view and prioritize security alerts across multiple AWS accounts and services, including findings from Amazon GuardDuty, Amazon Inspector, and AWS Config. AWS Security Hub would be the correct service to aggregate and manage these findings centrally.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓Amazon MacieCorrect answer▾
Why this is correct
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.
✗Amazon InspectorWrong answer — click to see why▾
Why this is wrong here
Amazon Inspector is designed for vulnerability management and network security assessments of EC2 instances and container workloads, not for discovering or classifying sensitive data in S3 buckets.
★ When this WOULD be the correct answer
An exam question asking which AWS service can automatically assess EC2 instances for software vulnerabilities and unintended network exposure, with no manual scanning required.
Why candidates choose this
Candidates may confuse 'automatically identify' with vulnerability scanning, assuming Inspector's automated assessment extends to data classification in S3.
✗AWS ConfigWrong answer — click to see why▾
Why this is wrong here
AWS Config evaluates resource configurations against rules but does not automatically scan data content for PHI. It cannot identify protected health information within S3 objects, which is required for HIPAA compliance.
★ When this WOULD be the correct answer
A company needs to continuously monitor and record changes to S3 bucket policies and ensure they comply with a custom rule (e.g., requiring encryption or blocking public access). AWS Config would be the correct service to track configuration changes and trigger alerts for non-compliant resources.
Why candidates choose this
Candidates may confuse AWS Config's ability to monitor resource configurations with the need to scan data content, assuming that 'identify' includes data classification, but Config only checks metadata and settings, not object contents.
✗AWS Security HubWrong answer — click to see why▾
Why this is wrong here
AWS Security Hub aggregates security findings from multiple services but does not automatically scan S3 buckets for PHI. It relies on other services like Amazon Macie to provide such findings, so it cannot directly identify PHI in S3.
★ When this WOULD be the correct answer
A company wants a single pane of glass to view and prioritize security alerts across multiple AWS accounts and services, including findings from Amazon GuardDuty, Amazon Inspector, and AWS Config. AWS Security Hub would be the correct service to aggregate and manage these findings centrally.
Why candidates choose this
Candidates may think Security Hub provides comprehensive security monitoring including data classification, but it is a centralized dashboard that requires other services to generate findings, not a data scanning service itself.

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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
