This MLA-C01 practice question tests your understanding of ml model development. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure IAM policies to restrict access to SageMaker resources
Option A is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Related concept
Read the scenario before looking for a memorised answer.
✗
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
Read the scenario before looking for a memorised answer.
✗
Use SageMaker Network Isolation
Why it's wrong here
Network isolation prevents internet access but does not encrypt data in transit.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network isolation (Option E) with encryption or access control, but network isolation only restricts network connectivity, not data encryption or authorization.
Detailed technical explanation
How to think about this question
S3 server-side encryption (SSE-S3 or SSE-KMS) encrypts training data at rest using AES-256, while using a VPC with private subnets and VPC endpoints ensures data in transit stays within the AWS network (via AWS PrivateLink) without traversing the public internet. IAM policies can be scoped to specific SageMaker actions (e.g., sagemaker:CreateTrainingJob) and resource ARNs, enabling least-privilege access to training artifacts stored in S3 or ECR.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
