You must be able to pick the right SageMaker algorithm, training mode, and regularization for a described failure, then justify it with the correct objective metric. The single most important thing is matching the symptom—overfitting, vanishing gradients, slow training—to its specific remedy.

Domain overview
The Modeling domain covers selecting, training, tuning, and evaluating models on AWS. Questions present SageMaker scenarios—built-in algorithms, custom training jobs, hyperparameter tuning, and debugging—and ask you to choose the correct technique or configuration. Expect applied reasoning about overfitting, vanishing gradients, distributed training, and evaluation metrics rather than pure theory.
Exam objectives
Choosing SageMaker built-in algorithms and frameworks like XGBoost, BlazingText, or SSD for a given task
Configuring training jobs with Pipe Mode, File Mode, and distributed data or model parallelism
Applying regularization, batch normalization, and residual connections to fix vanishing gradients or overfitting
Using SageMaker Automatic Model Tuning, Debugger, and Clarify to optimize and evaluate models
Confusing L1/L2 regularization with dropout or early stopping when the question specifically asks about vanishing gradients in deep networks
Assuming Pipe Mode always helps; it streams data and suits large datasets but can hurt algorithms needing random access
Treating Automatic Model Tuning as a replacement for proper objective metric selection or ignoring validation-set overfitting
