AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A financial services company uses Amazon SageMaker to train models with sensitive customer data. They must ensure that no data leaves a specific AWS Region due to data residency regulations. The training data is in S3. Which architecture meets this requirement while minimizing data transfer?
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 S3 VPC endpoints and place SageMaker training job in a private subnet with no internet access
Using a VPC with S3 VPC endpoints ensures data stays within the AWS network and does not traverse the internet. Data remains in the same Region because S3 endpoints are Regional.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place SageMaker training job in a private subnet with a NAT gateway and route traffic through the internet
Why it's wrong here
NAT gateway sends traffic to the internet, which could cross regions.
- ✗
Configure S3 Transfer Acceleration and use a public SageMaker training job
Why it's wrong here
Transfer Acceleration uses edge locations and could cause data to leave the region.
- ✗
Use AWS Glue to copy data to an EBS volume attached to the training instance
Why it's wrong here
Glue would still need to access S3, and EBS volumes are in the same AZ, but the initial data transfer may not be controlled.
- ✓
Use S3 VPC endpoints and place SageMaker training job in a private subnet with no internet access
Why this is correct
VPC endpoints keep S3 traffic within AWS network and same region; no internet access ensures residency.

| 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 |
