Machine Learning Associate: practice questions
Original practice questions for the ML lifecycle on Databricks: MLflow tracking, models in Unity Catalog, the feature store, AutoML, and serving. Concept questions here are citation-grounded in the current docs rather than executed, and every answer links its source.
ML Associate set
12 questions, drawn fresh from the bank. Every code question was executed on Spark before it shipped, and each answer links to the documentation it rests on.

A sample question, with the answer
You load a model with models:/main.ml.churn@champion. What does @champion refer to?
- aThe model version with the highest accuracy metric
- bA mutable alias a person or job assigned to some versioncorrect
- cThe most recently registered version
- dA Unity Catalog tag filtered at query time
Why: Aliases are named, mutable pointers to a specific model version in Unity Catalog. Retraining can move @champion to a new version without touching the serving code that loads it, which is exactly what the old fixed stage names could not do cleanly.

I am preparing for the Databricks Certified Machine Learning Associate exam. Quiz me with 10 original multiple-choice questions in the style of that exam, one at a time, across these areas: mlflow, unity-catalog. Never reuse real exam content. Do not show the answer until I respond. After each answer, explain why, and ground the explanation in docs.databricks.com. Keep score. At the end, list my weakest areas and what to read for each.

Frequently asked
How many questions is the Databricks Machine Learning Associate exam?
48 scored questions in 90 minutes, per the official exam guide dated March 1, 2025. It costs $200, is proctored, and the credential is valid for two years. Databricks does not publish the passing score.
Are these real exam questions?
No. Every question is original, written from public documentation with the supporting page cited next to the answer. Real exam content is covered by the exam NDA, and Databricks warns that dumps can void a certification.
Why are these questions not marked as executed on Spark?
The ML set is concept questions grounded in cited documentation, because MLflow tracking servers, Unity Catalog registries, and serving endpoints cannot be reproduced on a local Spark engine the way DataFrame semantics can. The citation next to each answer is the check.
