Test Your Knowledge of DataBricks Machine Learning Associate

A data scientist needs to quickly build a baseline classification model to predict customer churn without writing extensive code.

Which Databricks feature enables rapid baseline model creation with minimal code?

A) Databricks AutoML, which automatically trains and evaluates multiple models and generates a notebook with the best-performing approach
B) Writing a custom neural network from scratch
C) Using Databricks SQL dashboards
D) Manually testing algorithms one at a time in a spreadsheet

 

Correct answers: A – Explanation:
AutoML automatically trains, evaluates, and ranks models with generated notebooks. Custom neural networks (B) are slower for baselines. Dashboards (C) are for visualization. Manual testing (D) is inefficient.

The team wants to track every model training run including parameters, metrics, and artifacts for reproducibility and comparison.

Which tool should be used for experiment tracking in Databricks?

A) MLflow tracking with experiment runs recording parameters, metrics, and model artifacts
B) Saving results in text files on local disk
C) Taking screenshots of notebook output cells
D) Maintaining a spreadsheet of model results

 

Correct answers: A – Explanation:
MLflow tracking provides structured experiment logging with comparisons. Text files (B) lack searchability. Screenshots (C) are not queryable. Spreadsheets (D) are manual and error-prone.

Feature values like customer lifetime value and average order frequency need to be computed once and reused across multiple ML models consistently.

Which Databricks component enables centralized, reusable feature management?

A) Databricks Feature Store for creating, storing, and serving features across models with lineage tracking
B) Recomputing features from raw data for every model
C) Storing features in unmanaged CSV files
D) Hardcoding feature values in each notebook

 

Correct answers: A – Explanation:
Feature Store provides centralized, reusable features with lineage. Recomputing (B) wastes resources. CSV files (C) lack governance. Hardcoding (D) creates inconsistency.

After training a model, the data scientist needs to evaluate whether it generalizes well to unseen data and select the best model variant.

What evaluation approach ensures a model generalizes well?

A) Use cross-validation, evaluate on a held-out test set with appropriate metrics (AUC, F1, RMSE), and compare model variants in MLflow
B) Evaluate only on the training data
C) Select the model with the most parameters
D) Choose the fastest model regardless of accuracy

 

Correct answers: A – Explanation:
Cross-validation and test-set evaluation with proper metrics assess generalization. Training-only evaluation (B) risks overfitting. More parameters (C) do not mean better performance. Speed alone (D) ignores quality.

The data scientist needs to explore a new dataset to understand distributions, correlations, and potential data quality issues before modeling.

What is the recommended approach for exploratory data analysis on Databricks?

A) Use Databricks notebooks with pandas profiling, visualization libraries, and summary statistics to understand data distributions and quality
B) Skip exploration and start modeling immediately
C) Only look at the first 5 rows of data
D) Use AutoML without any data understanding

 

Correct answers: A – Explanation:
Thorough EDA with profiling and visualization reveals data patterns and issues. Skipping EDA (B) risks building on flawed data. Five rows (C) are insufficient. AutoML without understanding (D) may produce poor results.

A categorical feature with 500 unique values needs to be prepared for model training without introducing excessive dimensionality.

Which feature engineering technique handles high-cardinality categorical variables efficiently?

A) Target encoding, frequency encoding, or embedding layers that capture category information without creating 500 one-hot columns
B) One-hot encoding all 500 categories
C) Dropping the feature entirely
D) Converting categories to sequential integers without encoding

 

Correct answers: A – Explanation:
Target/frequency encoding or embeddings handle high cardinality efficiently. One-hot (B) creates excessive dimensions. Dropping (C) loses information. Sequential integers (D) imply false ordinal relationships.

The trained model needs to be registered and versioned so it can be promoted through staging to production environments.

Which MLflow component manages model versioning and environment promotion?

A) MLflow Model Registry with version tracking and stage transitions (Staging, Production, Archived)
B) Saving model files with date-stamped filenames
C) Emailing model files between teams
D) Manually testing algorithms one at a time in a spreadsheet

 

Correct answers: A – Explanation:
Model Registry provides formal versioning and stage management. Date-stamped files (B) lack formal promotion. Email (C) lacks governance. No versioning (D) prevents rollback.

The model needs to be deployed as a real-time API endpoint so the web application can get predictions on individual customer records.

How should the model be deployed for real-time serving on Databricks?

A) Deploy using Databricks Model Serving endpoints that provide REST API access for real-time inference
B) Run a notebook manually for each prediction request
C) Export the model to a spreadsheet for manual lookups
D) Batch-score all possible inputs in advance

 

Correct answers: A – Explanation:
AutoML automatically trains, evaluates, and ranks models with generated notebooks. Custom neural networks (B) are slower for baselines. Dashboards (C) are for visualization. Manual testing (D) is inefficient.

The data scientist suspects the model is overfitting because training accuracy is 98% but test accuracy is only 72%.

What techniques should be applied to address model overfitting?

A) Apply regularization, reduce model complexity, increase training data, use cross-validation, and implement early stopping
B) Increase model complexity to fit training data better
C) Remove the test set and evaluate only on training data
D) Accept the gap as normal model behavior

 

Correct answers: A – Explanation:
Regularization, simplification, more data, and early stopping combat overfitting. More complexity (B) worsens overfitting. Removing test sets (C) hides the problem. A 26-point gap (D) is not normal.

The team needs to tune hyperparameters like learning rate, max depth, and number of estimators to find the optimal model configuration.

What is the recommended approach for hyperparameter tuning on Databricks?

A) Use Hyperopt or Optuna integrated with MLflow to run distributed hyperparameter search with automatic logging of all trial results
B) Manually try three parameter combinations
C) Use default parameters for all models
D) Random parameter selection without tracking results

 

Correct answers: A – Explanation:
Distributed search with Hyperopt/Optuna and MLflow logging efficiently optimizes hyperparameters. Manual trials (B) are slow. Defaults (C) may be suboptimal. Untracked random search (D) prevents learning from results.
