AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A machine learning team is training a model using Amazon SageMaker with data stored in an S3 bucket. The security policy requires that all data be encrypted at rest and in transit, and that the training job cannot access the internet. Which combination of settings should the team use?
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
✓
Disable Network Isolation, place the training job in a private VPC subnet, and use an S3 VPC Endpoint
SageMaker training jobs can be run in a VPC without internet access by disabling 'Enable Network Isolation' (which actually blocks all network access) and using a VPC with no NAT gateway or internet gateway. KMS encryption for both S3 and the attached ML storage volume ensures encryption at rest.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Network Isolation and use an S3 VPC Endpoint
Why it's wrong here
Network Isolation blocks all network access including S3, so the job cannot read data from S3 even with a VPC endpoint.
- ✓
Disable Network Isolation, place the training job in a private VPC subnet, and use an S3 VPC Endpoint
Why this is correct
This allows the job to access S3 via the VPC endpoint without internet access, meeting the no-internet requirement.
- ✗
Enable Network Isolation and use a VPC with a NAT gateway
Why it's wrong here
Network Isolation prevents all network access, so even a NAT gateway cannot be used. Also, NAT gateway provides internet access.
- ✗
Disable Network Isolation and use a public VPC subnet
Why it's wrong here
A public subnet has internet access via an internet gateway, violating the no-internet policy.
