MLS-C01 Practice Question: Machine Learning Implementation and Operations
A data scientist needs to perform hyperparameter optimization for a gradient boosting model. Which built-in Amazon SageMaker feature should they use?
⚠ Common exam trap
Many candidates confuse SageMaker Debugger's monitoring capabilities (e.g., capturing loss curves) with the active optimization of hyperparameters, but Debugger only observes and reports, it does not suggest or iterate on hyperparameter values.

Correct answer & explanation
✓
Amazon SageMaker Automatic Model Tuning
Amazon SageMaker Automatic Model Tuning (A) is the built-in feature specifically designed for hyperparameter optimization. It automates the search for the best combination of hyperparameters by launching multiple training jobs with different hyperparameter values, using strategies like Bayesian optimization, random search, or Hyperband. This directly addresses the data scientist's need to optimize a gradient boosting model's hyperparameters.
