MLA-C01 ML Model Development Practice Question
A financial services company trains multiple models on SageMaker and needs to track hyperparameters, metrics, and artifacts for each experiment. Which SageMaker feature should they use to organize and compare experiments?
⚠ Common exam trap
MLA-C01 often tests the confusion between SageMaker Experiments (tracking/comparing runs) and Model Registry (versioning/approving models) — both involve 'models' but serve different lifecycle stages.

Correct answer & explanation
✓
SageMaker Experiments
SageMaker Experiments is purpose-built for tracking, organizing, and comparing machine learning experiments — it captures hyperparameters, metrics, input datasets, and output artifacts for each trial and groups them into experiments and runs. This lets data scientists visualize and compare results across many training jobs in a single view.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SageMaker Model Registry
Why it's wrong here
Model Registry catalogues trained model versions and their approval status for deployment; it stores no hyperparameter, metric or artifact tracking across runs. It is tempting because it organises models, and would be correct when promoting a validated model version through approval stages to a production endpoint.
- ✗
SageMaker Pipelines
Why it's wrong here
Pipelines orchestrates reproducible ML workflows as directed acyclic graphs of processing, training and registration steps; it does not itself record and compare per-experiment runs. It is tempting because it automates training, and would be correct when the requirement is CI/CD-style automation of an end-to-end workflow.
- ✓
SageMaker Experiments
Why this is correct
SageMaker Experiments groups training runs into experiments and trials, automatically capturing hyperparameters, metrics, and artifacts for each job. This directly satisfies the requirement to organise and compare runs across multiple models, providing the lineage and side-by-side analysis the financial services company needs.
- ✗
SageMaker Debugger
Why it's wrong here
Debugger captures tensors and analyses training anomalies such as vanishing gradients or overfitting during a job; it holds no experiment-tracking store for comparing runs. It is tempting because it monitors training metrics, and would be correct when diagnosing why a specific training job converges poorly.
