Test Your Knowledge of DataBricks Machine Learning Professional
Question #1
A senior ML engineer needs to train a model on a dataset too large to fit in memory on a single machine.
What approach should be used for distributed model training on Databricks?
A) Use SparkML for distributed training across cluster nodes, or use distributed deep learning frameworks like Horovod or TorchDistributor
B) Subsample the data to fit on one machine
C) Use a pandas DataFrame on the driver node only
D) Train separate models on random data splits and average predictions
Solution
Correct answers: A – Explanation:
SparkML and distributed frameworks scale training across clusters. Subsampling (B) loses information. Single-node pandas (C) does not scale. Averaging separate models (D) is not distributed training.
Question #2
Hyperparameter tuning needs to evaluate hundreds of configurations efficiently across a distributed Databricks cluster.
Which tools should be used for distributed hyperparameter tuning?
A) Ray Tune or Optuna with Databricks integration for parallel trial execution across cluster workers with MLflow tracking
B) Sequential grid search on a single machine
C) Manually testing one configuration at a time
D) Using default hyperparameters without any tuning
Solution
Correct answers: A – Explanation:
Ray/Optuna distribute tuning across workers with MLflow tracking. Sequential grid search (B) is slow. Manual testing (C) is inefficient. Default parameters (D) miss optimization opportunities.
Question #3
The ML team needs to manage the full model lifecycle from experimentation through staging, production deployment, and retirement.
How should the model lifecycle be managed at enterprise scale?
A) Use MLflow with Unity Catalog model management for versioning, stage transitions, access controls, and lineage tracking across the model lifecycle
B) Save model files to shared folders with naming conventions
C) Track models in a shared spreadsheet
D) Deploy models without any lifecycle management
Solution
Correct answers: A – Explanation:
MLflow with Unity Catalog provides enterprise model lifecycle management. Shared folders (B) lack governance. Spreadsheets (C) are error-prone. No management (D) creates operational risk.
Question #4
Feature pipelines need to run automatically on a schedule, computing and updating feature values used by multiple production models.
How should automated Feature Store pipelines be implemented?
A) Create scheduled Databricks Jobs that compute features and write to Feature Store tables with Unity Catalog governance
B) Manually recompute features before each model training
C) Hardcode feature values and never update them
D) Compute features only at model serving time
Solution
Correct answers: A – Explanation:
Scheduled jobs automate feature computation with governance. Manual recomputation (B) is unreliable. Hardcoded values (C) become stale. Serving-time computation (D) adds latency.
Question #5
The team needs MLOps practices including automated testing, environment management, and deployment automation for ML pipelines.
What MLOps tooling should be used for CI/CD of ML pipelines on Databricks?
A) Databricks Asset Bundles for pipeline packaging, Git integration for version control, and automated testing in staging before production promotion
B) Deploy models directly to production without testing
C) Manual notebook execution for each deployment
D) Use only local development without any production pipeline
Solution
Correct answers: A – Explanation:
Asset Bundles, Git, and automated testing enable ML CI/CD. Direct deployment (B) risks failures. Manual execution (C) is unreliable. Local-only development (D) prevents production deployment.
Question #6
A production model’s prediction accuracy has degraded over time, and the team suspects data drift is the cause.
How should model and data drift be detected and addressed?
A) Use Databricks Lakehouse Monitoring to track data drift, prediction drift, and model performance metrics with automated alerts and retraining triggers
B) Ignore accuracy degradation and hope it recovers
C) Retrain the model on the same historical data
D) Manually compare prediction distributions quarterly
Solution
Correct answers: A – Explanation:
Lakehouse Monitoring detects drift with automated alerts and retraining triggers. Ignoring degradation (B) worsens outcomes. Same data retraining (C) does not address drift. Quarterly manual checks (D) miss issues between reviews.
Question #7
An automated retraining workflow should trigger when monitoring detects that model performance drops below an acceptable threshold.
How should automated model retraining be implemented?
A) Configure Databricks Jobs triggered by monitoring alerts that execute the training pipeline, register the new model in MLflow, and promote upon validation
B) Manually retrain whenever someone notices poor predictions
C) Schedule retraining on a fixed calendar regardless of performance
D) Train separate models on random data splits and average predictions
Solution
Correct answers: A – Explanation:
Alert-triggered automated retraining with validation ensures quality. Manual retraining (B) is reactive. Calendar-based (C) may retrain unnecessarily or too late. Never retraining (D) guarantees degradation.
Question #8
The ML engineer needs to implement A/B testing to compare a new model version against the current production model.
How should A/B testing be configured for model comparison?
A) Use Model Serving traffic splitting to route a percentage of requests to the new model while monitoring comparative metrics
B) Deploy the new model to all users immediately
C) Test only on synthetic data
D) Compare models using only training metrics
Solution
Correct answers: A – Explanation:
SparkML and distributed frameworks scale training across clusters. Subsampling (B) loses information. Single-node pandas (C) does not scale. Averaging separate models (D) is not distributed training.
Question #9
A complex ML workflow involves data preparation, feature engineering, model training, evaluation, and deployment as interconnected stages.
How should multi-stage ML workflows be orchestrated?
A) Design a Databricks Jobs workflow with task dependencies connecting each ML stage, with conditional logic for promotion based on evaluation results
B) Run each stage manually in sequence
C) Combine all stages into a single monolithic notebook
D) Skip workflow orchestration and run stages independently
Solution
Correct answers: A – Explanation:
Jobs workflows with dependencies and conditional logic orchestrate complex ML pipelines. Manual sequencing (B) is error-prone. Monolithic notebooks (C) lack modularity. Independent stages (D) lose coordination.
Question #10
The team needs to ensure ML models meet fairness, explainability, and regulatory compliance requirements before production deployment.
How should responsible AI practices be implemented in the ML pipeline?
A) Integrate fairness metrics evaluation, model explainability tools (SHAP, LIME), bias detection, and compliance documentation into the MLflow-tracked pipeline
B) Deploy models without any fairness or explainability checks
C) Only check compliance after customer complaints
D) Rely on model accuracy as the sole quality metric
Solution
Correct answers: A – Explanation:
Integrated fairness, explainability, and compliance checks ensure responsible AI. Skipping checks (B) risks harm. Reactive compliance (C) is too late. Accuracy alone (D) ignores fairness and regulatory needs.
