AIF-C01 Practice Question: Using Amazon Textract to extract text from…
A company is using Amazon Textract to extract text from scanned documents stored in an S3 bucket. The security team requires that all access to the documents be logged and that the documents be encrypted at rest using a customer-managed key. What should the company do to meet these requirements?
⚠ Common exam trap
Test-takers frequently confuse S3 server access logs with CloudTrail data events, assuming both provide equivalent logging, but only CloudTrail data events offer reliable, real-time, and comprehensive object-level access logging required for security audits.

Correct answer & explanation
✓
Enable S3 server-side encryption with AWS KMS (SSE-KMS) and enable CloudTrail data events for the S3 bucket
Enabling S3 server-side encryption with AWS KMS (SSE-KMS) satisfies the requirement for encryption at rest using a customer-managed key, and enabling CloudTrail data events for the S3 bucket captures all access to the documents (including GetObject, PutObject, etc.) for logging. This combination meets both security requirements precisely.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use S3 default encryption and enable Textract logging
Why it's wrong here
Textract does not have its own logging; S3 default encryption uses SSE-S3.
- ✓
Enable S3 server-side encryption with AWS KMS (SSE-KMS) and enable CloudTrail data events for the S3 bucket
Why this is correct
SSE-KMS provides encryption with customer-managed keys; CloudTrail data events log access to objects.
- ✗
Enable S3 server access logs and use S3 SSE-KMS
Why it's wrong here
S3 server access logs do not provide the same level of auditing as CloudTrail data events.
- ✗
Use S3 server-side encryption with S3-managed keys (SSE-S3) and enable S3 access logs
Why it's wrong here
SSE-S3 does not use customer-managed keys; S3 access logs do not capture all API activity like CloudTrail.

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 |
