MLA-C01 ML Model Development Practice Question
A data scientist is using SageMaker Autopilot to automatically build a binary classification model on a balanced dataset. They want to understand the relationship between the input features and the model predictions. Which feature in SageMaker Autopilot should they use?
⚠ Common exam trap
MLA-C01 often tests the difference between data exploration features and model interpretability features — candidates may confuse 'data visualizations' (which describe the dataset) with 'explainability reports' (which describe the model).

Correct answer & explanation
✓
Explainability reports
SageMaker Autopilot's explainability reports provide feature importance and partial dependence plots (PDPs) that show how each input feature influences model predictions. For a binary classification model, these reports help data scientists understand the relationship between features and predictions. This is exactly what the question asks for.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Explainability reports
Why this is correct
Explainability reports quantify each feature's contribution to predictions, satisfying the requirement to understand feature-prediction relationships. Autopilot generates these automatically for classification models, using SHAP values to attribute prediction outcomes to individual input features, revealing both global importance and per-instance effects without manual analysis.
- ✗
Data visualizations
Why it's wrong here
Data visualizations in Autopilot describe distributions, missing values and target balance in the dataset, not how features influence predictions. It is tempting because exploratory charts precede modelling, and it would be right for assessing data quality before training rather than interpreting feature-prediction relationships.
- ✗
Model tuning results
Why it's wrong here
Model tuning results list candidate hyperparameter configurations and their objective metrics, not feature attribution. It is tempting because tuning output explains which model performed best, and it would be the answer if the question asked how to select an optimal model rather than interpret feature influence on predictions.
- ✗
Model candidate definitions
Why it's wrong here
Model candidate definitions describe the algorithms and preprocessing pipelines Autopilot generated, not the contribution of individual features to predictions. It is tempting because candidates reveal how models were built, and it would be correct for comparing pipeline approaches rather than explaining feature-prediction relationships.
