Databricks Machine Learning Professional exam format
Use the official format to set your pace before choosing a question bank or building a study schedule.
Experience guidance: There is no formal prerequisite, but Databricks recommends at least one year of hands-on experience performing the machine-learning tasks in the guide. ANSI SQL can be tested.
Allocate study time by weight
Current exam domains and weighting
Model Development and MLOps together account for 88% of the published blueprint. Treat deployment as important, but do not let it displace the two largest domains.
Model Development
Spark ML pipelines, distributed training, MLflow and production feature engineering.
MLOps
Lifecycle automation, testing, retraining, Databricks Asset Bundles and Lakehouse Monitoring.
Model Deployment
Safe rollout strategies, Unity Catalog models and programmatic serving workflows.
Avoid outdated study lists
What the current Databricks ML Professional blueprint covers
The official guide effective September 30, 2025 materially emphasizes scalable training, managed features, automated MLOps, monitoring and production serving.
Model Development
- Choose and use Spark ML estimators, transformers, pipelines, evaluation, tuning and batch or streaming inference.
- Scale training with Spark and pandas function APIs, grouped model training, Optuna with MLflow, and Ray.
- Reason about horizontal versus vertical scaling, data versus model parallelism, and when Ray or Spark is appropriate.
- Use advanced MLflow capabilities, including nested runs, custom metrics, parameters, artifacts and custom models.
- Build point-in-time-correct features, automated feature pipelines, online tables, streaming features and on-demand features.
MLOps
- Design environment transitions, deployment workflows, unit tests and integration tests for ML systems.
- Use Databricks Asset Bundles to manage experiments, models and model-serving resources across environments.
- Automate retraining using drift or performance triggers and select the best candidate model.
- Configure Lakehouse Monitoring for snapshot, time-series and inference tables; add alerts, custom metrics and slices.
- Interpret drift comparisons, model-performance trends and serving-endpoint health signals.
Model Deployment
- Choose blue-green or canary deployment strategies and implement gradual rollout with Model Serving.
- Package custom PyFunc models and artifacts in Unity Catalog.
- Deploy through REST APIs or the MLflow Deployments SDK and serve custom models safely.

4 free Databricks Machine Learning Professional practice questions
These are original learning questions based on public objectives—not live exam questions, recalled content or leaked Databricks exam dumps. Choose an answer, then open the explanation.
0 of 4 answers reviewed
Question 1 · Distributed training
A team must train a separate model for each of several thousand stores. Each store's data and model fit comfortably in a worker's memory. Which approach best distributes this workload?
- Train all stores sequentially on the driver.
- Use a grouped pandas function API so each group can train independently across the cluster.
- Increase only the driver's memory and keep a single training task.
- Use model parallelism to split every small store model across all workers.
Show answer and explanation
Answer: B. Grouped model training is a natural fit when independent groups can be trained in parallel and each group's workload fits on one worker. Driver-only training underuses the cluster, while model parallelism adds unnecessary complexity.
Question 2 · Feature engineering
A training table contains historical events. The team must prevent a feature lookup from using values recorded after each label timestamp. What capability addresses this requirement?
- Point-in-time feature lookup correctness
- Randomly shuffle all event timestamps
- Cache only the newest feature values
- Increase the feature table's retention period
Show answer and explanation
Answer: A. Point-in-time-correct lookups use the value that was available at the relevant event time, reducing future-data leakage in training examples.
Question 3 · MLOps
A team wants version-controlled definitions for an MLflow experiment, a Unity Catalog model and a serving endpoint, promoted consistently through development and production. What is the best fit?
- A manually maintained notebook for each workspace
- A cluster init script containing resource IDs
- A Databricks Asset Bundle with environment-specific targets
- A dashboard that documents the deployment steps
Show answer and explanation
Answer: C. Databricks Asset Bundles provide source-controlled resource definitions and deployment targets, supporting repeatable promotion of ML resources across environments.
Question 4 · Model deployment
A team wants to expose a new model version to a small portion of production traffic, evaluate model and endpoint health, then increase traffic gradually. Which rollout matches this goal?
- Immediately replace the only served model for all requests.
- Create a second served entity and use a canary traffic split while monitoring results.
- Export predictions to a static file before every request.
- Keep both versions offline and compare only training metrics.
Show answer and explanation
Answer: B. A canary rollout sends limited live traffic to the new version, providing evidence from production before the allocation is increased or rolled back.
