Databricks-ML-Assoc ML Workflows Practice Question
A data scientist is training a machine learning model on Databricks and needs to log parameters, metrics, and model artifacts. Which tracking component should be used to ensure the reproducibility of the experiment runs?
⚠ Common exam trap
Candidates select general storage solutions like DBFS or standard cloud buckets, overlooking the dedicated MLflow tracking component designed specifically for reproducibility.

Correct answer & explanation
✓
MLflow Tracking
MLflow Tracking is the core component for logging parameters, code versions, metrics, and output files when running machine learning code. By recording these artifacts, teams can compare multiple runs, track model lineage, and ensure that experiments are reproducible across different environments. Integrating MLflow into the workflow is essential for transitioning from local notebook experimentation to production-ready MLOps pipelines within the Databricks ecosystem.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Databricks Feature Store
Why it's wrong here
The Feature Store is designed for storing, sharing, and managing curated feature data for training and inference. It does not provide the experiment logging capabilities required to track hyperparameters or model metrics across individual training runs, which is the primary purpose of the MLflow Tracking module.
- ✗
MLflow Model Registry
Why it's wrong here
The Model Registry manages the lifecycle of registered models, including versioning, stage transitions like Staging to Production, and annotations. While it works closely with MLflow Tracking, it is not the correct component for the initial logging of hyperparameters and metrics during the active training experiment phase.
- ✓
MLflow Tracking
Why this is correct
MLflow Tracking provides a robust API and UI for logging parameters, code versions, metrics, and output artifacts. It serves as the primary tool for experiment management, allowing users to organize runs into experiments, compare results visually, and maintain a historical audit trail of model development workflows.
- ✗
Delta Lake Versioning
Why it's wrong here
Delta Lake versioning tracks data changes and provides time travel capabilities for datasets. While it ensures data reproducibility, it does not capture the specific machine learning parameters, model metrics, or artifacts generated by training code, which are necessary for experiment tracking and model comparison purposes.
