Databricks Certified Machine Learning Professional Sample Questions (Q33-Q38):

NEW QUESTION # 33
A data scientist would like to switch from manually using MLflow logging to MLflow Autologging for all machine learning libraries used in a notebook.
They begin by adding mlflow.autolog()to the top of the below code block:

The data scientist is now trying to determine which line of code will kick off the MLflow Autologging process.
Which line of code within the above code block will start the MLflow Autologging process?

A. mlflow.log_metric("training_mse", mse)
B. mlflow.sklearn.log_model(rf_model, "rf_model")
C. rf_model = rf.fit(X_train, y_train)
D. with mlflow.start_run(run_name="ML Project") as run:

Answer: C

Explanation:
The MLflow Autologging process is triggered when a model's training function is called. In this case, rf.fit(X_train, y_train) starts the autologging process because mlflow.autolog() automatically tracks parameters, metrics, and the model when a supported estimator (like RandomForestRegressor) is fitted. The context manager mlflow.start_run() only initiates an MLflow run, but the actual autologging begins during the .fit() execution.

NEW QUESTION # 34
A Machine Learning Engineer needs to build a time series model. In Databricks, they have created isolated environments in different workspaces for development, staging, and production.
To manage this model, they are planning on using a "deploy code" strategy. They are concerned that the model trained in development will not remain consistent across environments, due to differences in the dependencies installed. What can they do to ensure that the model is trained with the same packages?

A. Use MLflow to track the model parameters and metrics in development, then export the same training conditions in staging and production.
B. Use the same Databricks Runtime (DBR) version across environments and define dependencies in a lock file that is installed as part of the job.
C. Use Databricks Repos to store the model code and install the required libraries in the notebook.
D. Use custom init scripts that install the necessary packages as part of the job.

Answer: B

Explanation:
Using the same Databricks Runtime across environments ensures a consistent base environment, and installing dependencies from a lock file guarantees identical package versions during training. This combination follows best practices for deploy-code workflows by making the training environment reproducible and preventing dependency drift between development, staging, and production.

NEW QUESTION # 35
Which of the following lists all of the model stages are available in the MLflow Model Registry?

A. Staging. Production. Archived
B. None. Staging. Production. Archived
C. Development. Staging. Production
D. Development. Staging. Production. Archived
E. None. Staging. Production

Answer: B

NEW QUESTION # 36
A Machine Learning Engineer has deployed a fraud detection model that processes 10,000 transactions per hour. The model was trained on data from Q1 2024, but it's now Q4 2024. The ML team notices three concerning trends: (1) the model's precision has dropped from 92% to
78% over the past month, (2) the average transaction amount in recent data has increased from
$150 to $220 and (3) the relationship between transaction frequency and fraud likelihood has weakened significantly due to new payment methods being introduced. The engineer needs to implement a monitoring solution that can detect the root cause of the performance degradation, identify why the precision dropped, and be able to do this at the scale needed. Which monitoring pipeline component will do this?

A. Drift Detection Pipeline because it can identify both the data drift (transaction amount changes) and concept drift (weakened relationship between features and target).
B. Model Performance Monitoring Pipeline because it directly tracks precision metrics and can alert when thresholds are breached.
C. Logging and Monitoring Pipeline because it captures all prediction requests and can identify patterns in the fraud predictions.
D. Model Health Monitoring Pipeline because it ensures the infrastructure can handle the 10,000 transactions per hour load.

Answer: A

Explanation:
A drift detection pipeline is designed to diagnose the root causes of model performance degradation at scale. It can detect data drift, such as changes in the distribution of transaction amounts, and concept drift, where the relationship between input features and the fraud label changes due to new payment methods. This directly explains why precision dropped and provides actionable insight beyond simply observing metric degradation.

NEW QUESTION # 37
A Machine Learning Engineer has trained a credit scoring model and needs to evaluate fairness metrics across different customer segments while maintaining different levels of granularity for business reporting. They need to compute metrics like precision, recall, and demographic parity at the individual feature level (credit_score_range, income_bracket) as well as intersectional slices (combinations of features). The model outputs are stored in a Delta table with prediction probabilities and actual default labels. The engineer wants to systematically evaluate model performance across these various feature slices and granularities. Which approach will do this?

A. Create Lakehouse Monitoring with slicing expressions for individual features and intersection conditions.
B. Use Unity Catalog metric views with dimensions defined for each feature and measures for the fairness metrics.
C. Implement custom MLflow evaluation functions that iterate through all possible feature combinations.
D. Build separate Spark DataFrames for each slice and compute metrics using standard DataFrame operations.

Answer: A

Explanation:
Lakehouse Monitoring supports defining slicing expressions on one or more columns, allowing metrics such as precision, recall, and fairness indicators to be computed at both individual feature levels and intersectional combinations. This provides a systematic, scalable, and governed way to evaluate model performance and fairness across multiple granularities directly from Delta tables without custom metric pipelines.
