MLA-C01 A company uses SageMaker to train a model Practice Question

A company uses SageMaker to train a model. They want to ensure that training data is encrypted at rest and in transit, and that only authorized users can access the training artifacts. Which three steps should they take? (Choose three.)

⚠ Common exam trap

Many candidates confuse network isolation (Option E) with encryption or access control, but network isolation only restricts network connectivity, not data encryption or authorization.

Correct answer & explanation

✓

Configure IAM policies to restrict access to SageMaker resources

IAM policies allow you to define fine-grained permissions to control which users or roles can create, describe, or delete SageMaker resources (e.g., training jobs, endpoints). By restricting access via IAM, you ensure that only authorized principals can interact with training artifacts, such as model output in S3 or logs in CloudWatch. This directly addresses the requirement of limiting access to authorized users.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
Configure IAM policies to restrict access to SageMaker resources
Why this is correct
Controls who can create, modify, and access SageMaker resources.
✗
Use SageMaker Model Monitor
Why it's wrong here
Model Monitor is for monitoring model quality, not encryption or access control.
✓
Use a VPC with private subnets and VPC endpoints
Why this is correct
Keeps traffic within the VPC and uses VPC endpoints for S3, ensuring encryption in transit.
✓
Enable S3 server-side encryption for training data
Why this is correct
Encrypts data at rest in S3.
✗
Use SageMaker Network Isolation
Why it's wrong here
Network isolation prevents internet access but does not encrypt data in transit.

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
