AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A company wants to automatically discover sensitive data such as credit card numbers in their Amazon S3 training datasets before using them for model training. Which AWS service should they use?
⚠ Common exam trap
AIF-C01 often tests the confusion between data classification services (Macie) and threat detection or compliance services (GuardDuty, Config, Audit Manager), so candidates must map 'sensitive data in S3' directly to Macie.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Macie
Amazon Macie is a fully managed data security service that uses machine learning and pattern matching to automatically discover, classify, and protect sensitive data stored in Amazon S3. It is purpose-built to detect PII such as credit card numbers, social security numbers, and API keys in S3 buckets, making it the correct choice for scanning training datasets before use.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon Macie
Why this is correct
Amazon Macie uses machine learning and pattern matching to automatically discover, classify and alert on sensitive data such as credit card numbers stored in Amazon S3. It directly satisfies the requirement to scan S3 training datasets before use, providing continuous visibility without manual inspection or custom scripts.
- ✗
AWS Config
Why it's wrong here
AWS Config records resource configuration changes and evaluates compliance rules; it does not inspect object contents for credit card numbers. It tempts because it audits S3 bucket settings, but detecting sensitive data inside objects requires Amazon Macie, which uses pattern matching and machine learning to identify PII in S3.
- ✗
Amazon GuardDuty
Why it's wrong here
GuardDuty detects anomalous activity and threats in accounts, workloads and logs; it does not scan S3 object contents for credit card numbers. It tempts because it monitors S3 for suspicious behaviour, but data discovery of sensitive content requires Amazon Macie's managed identifiers and custom data identifiers.
- ✗
AWS Audit Manager
Why it's wrong here
Audit Manager collects evidence and assesses controls against frameworks; it does not scan S3 objects for credit card numbers. It tempts because it supports compliance reporting, but discovering sensitive data within datasets is Amazon Macie's function, using pattern matching and machine learning classification of S3 objects.

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 |
