MLA-C01 Practice Question: An ML team uses SageMaker Model Registry to…
An ML team uses SageMaker Model Registry to manage model versions. They want to automatically deploy a model to a staging endpoint when a new version is approved. Which AWS service can orchestrate this?
⚠ Common exam trap
The trap here is that candidates often pick SageMaker Pipelines (Option C) because it is associated with model workflows, but Pipelines is for training and registration, not for post-approval deployment orchestration, which requires a state machine like Step Functions.

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 Step Functions
AWS Step Functions is the correct choice because it can orchestrate a workflow that triggers on a Model Registry event (e.g., model version approval) and then deploys the model to a staging endpoint using SageMaker SDK calls. Step Functions provides built-in integration with SageMaker via service integrations, allowing you to chain approval checks, model creation, and endpoint deployment without custom code.
