20+ practice questions focused on ML Workflows — one of the most tested topics on the Databricks Certified Machine Learning Associate exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start ML Workflows PracticeWhich TWO of the following statements regarding the MLflow Model Registry in Databricks are true?
Explanation: The MLflow Model Registry acts as a centralized repository for managing the full lifecycle of a machine learning model, including versioning, stage transitions, and annotations. Understanding the registry is crucial for MLOps, as it provides a single source of truth for production-ready models, enabling team collaboration and automated deployment pipelines by standardizing how models are promoted across development, staging, and production environments in a secure and audited manner.
Refer to the exhibit. You are logging a model to the MLflow Model Registry. What is the primary purpose of providing the model signature and input example shown in the exhibit?
Explanation: Providing a model signature and input example allows MLflow to define the expected schema for the model's inputs and outputs. This metadata is used by Databricks Model Serving to validate incoming requests, ensuring that the input features match the types and order expected by the model. This prevents runtime errors and is a critical practice for maintaining stable production inference pipelines in a distributed, multi-user environment.
When using the Databricks Feature Store, what is the primary benefit of logging the feature table metadata when training a model?
Explanation: Logging feature store metadata allows for automatic tracking of feature lineage. When a model is logged with its feature dependencies, MLflow captures which features were used, enabling better traceability and auditability. This is critical for ML workflows to ensure consistency, as it allows the system to automatically lookup the correct feature values for inference, eliminating training-serving skew where different feature logic might accidentally be applied in production compared to development.
Your organization requires that all models deployed to production are signed off by a human reviewer. Which Databricks feature should be used to enforce this workflow?
Explanation: The MLflow Model Registry provides stage transition states (Staging, Production, Archived). By using permissions or integrating with external CI/CD tools, organizations can enforce a gatekeeping process where a human must manually approve a transition to 'Production'. This workflow is crucial for governance, ensuring that every production model has undergone a rigorous review process, which minimizes the risk of deploying flawed or insecure models into mission-critical business environments.
Refer to the exhibit. A data scientist is setting up a Databricks Workflow task. Which statement accurately describes the function of the 'base_parameters' field?
Explanation: The 'base_parameters' field allows users to pass key-value pairs into a notebook at runtime. This capability is crucial for parameterizing workflows, enabling the same code to be reused with different configurations without code modifications. This promotes cleaner code management and supports hyperparameter tuning workflows where varying inputs are required for the same training script in different job runs, enhancing the modularity and reusability of the machine learning pipeline.

Start with 10 questions to gauge your current understanding of ML Workflows. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
ML Workflows questions on the Databricks-ML-Assoc frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
