AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A company has trained a model using Amazon SageMaker and stored the model artifacts in S3 with SSE-KMS encryption. The development team wants to grant cross-account access to the model artifacts so a partner can deploy the model in their own account. Which steps are required?
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
✓
Create an S3 bucket policy allowing the partner account to read the objects, and ensure the KMS key policy allows the partner account to use the key
To share SSE-KMS encrypted objects cross-account, you must grant the partner account access to both the S3 object (via bucket policy) and the KMS key (via key policy). The partner must also have the correct IAM permissions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a new IAM role in the partner account with S3 read permissions
Why it's wrong here
That role would need cross-account permissions from the source account, which requires the bucket policy and key policy.
- ✓
Create an S3 bucket policy allowing the partner account to read the objects, and ensure the KMS key policy allows the partner account to use the key
Why this is correct
Both S3 bucket policy and KMS key policy must grant cross-account access.
- ✗
Use AWS Lake Formation to share the data
Why it's wrong here
Lake Formation is for data lakes, not for sharing model artifacts.
- ✗
Copy the model artifacts to a public S3 bucket
Why it's wrong here
Making data public violates security best practices.
