AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A data scientist is training a model using Amazon SageMaker and needs to ensure the training data is encrypted at rest and in transit. The data is stored in S3. Which combination of steps meets this requirement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an S3 bucket with SSE-KMS encryption and configure the SageMaker training job to use a VPC with no internet access
S3 server-side encryption (SSE-S3 or KMS) protects data at rest. SageMaker uses HTTPS for data in transit between S3 and the training instance, and VPC configuration can enforce network isolation.
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 an S3 bucket with SSE-KMS encryption and configure the SageMaker training job to use a VPC with no internet access
Why this is correct
SSE-KMS encrypts data at rest; VPC with no internet ensures data in transit stays within AWS network, and SageMaker uses HTTPS for encryption.
- ✗
Enable S3 Transfer Acceleration and use a public SageMaker training job
Why it's wrong here
Transfer Acceleration speeds up transfers but does not provide encryption at rest or in transit beyond default HTTPS.
- ✗
Use client-side encryption before uploading to S3 and disable SageMaker internet access
Why it's wrong here
Client-side encryption alone does not ensure encryption at rest on S3; also, SageMaker training jobs require internet access for some features unless using VPC.
- ✗
Enable default S3 bucket encryption and use a SageMaker notebook instance in a private subnet
Why it's wrong here
The notebook instance is for development, not for training jobs. Training jobs need VPC configuration for network isolation.

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 |
