AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A company uses Amazon SageMaker to train sensitive ML models. Which AWS service should they use to encrypt the training data and model artifacts at rest?
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
✓
AWS Key Management Service (KMS)
AWS Key Management Service (KMS) allows customers to create and manage encryption keys used to encrypt data at rest in SageMaker, including training data and model artifacts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Secrets Manager
Why it's wrong here
Secrets Manager stores and rotates credentials, API keys and database passwords; it does not encrypt SageMaker training data or model artefacts at rest. It would be the right choice for holding a database password or access token used by a training script, not for encrypting stored objects.
- ✗
AWS CloudHSM
Why it's wrong here
CloudHSM provides dedicated single-tenant hardware security modules for key storage and cryptographic operations, not the encryption of SageMaker training data and artefacts. It would be correct where FIPS 140-2 Level 3 key custody or custom key operations are mandated, rather than standard at-rest encryption.
- ✓
AWS Key Management Service (KMS)
Why this is correct
AWS KMS provides the customer-managed keys that encrypt SageMaker training data in S3 and model artefacts at rest, satisfying the at-rest encryption requirement. KMS integrates natively with SageMaker and S3, unlike services handling in-transit encryption or access control.
- ✗
AWS Certificate Manager
Why it's wrong here
Certificate Manager provisions, manages and renews TLS/SSL certificates for HTTPS endpoints; it performs no encryption of stored data or model artefacts. It would be correct for securing an Application Load Balancer or CloudFront distribution with a public certificate, not for at-rest encryption of SageMaker resources.
