Sample Practice Questions with Answers
Question 1: MLflow Usage
Q: What does mlflow.log_metric() do in a training script?
A: It logs a single key-value pair for a metric to track experiment performance over time.
Question 2: Model Deployment
Q: How do you register a trained model into the model registry in Databricks?
A: Use mlflow.register_model() with the run URI and a model name.
Question 3: Feature Engineering
Q: What’s the best technique to handle high-cardinality categorical features?
A: Target encoding or embedding, depending on the model and data volume.
Detailed Answer Explanations
Why Each Answer Is Correct
Understanding not just the right answer—but why it’s right—is crucial for applying the concept later.
Common Mistakes and Traps to Avoid
Many learners confuse logging metrics with logging parameters or forget to enable autologging.
