Databricks Certified Machine Learning Professional Sample Questions (Q165-Q170):

NEW QUESTION # 165
Which of the following lists all of the model stages are available in the MLflow Model Registry?

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

Answer: C

NEW QUESTION # 166
A Machine Learning Engineer is responsible for maintaining a fraud detection model deployed on Databricks. They want to implement a retraining pipeline that automatically starts when the model's F1 score drops below a threshold or when input feature distributions change significantly.
Which two actions should the engineer take to implement this automated retraining? (Choose two.)

A. Schedule a recurring query on the Lakehouse monitoring table.
B. Use MLflow to manually log metrics and retrain the model offline.
C. Configure these alerts to send webhook notifications that trigger the model training job.
D. Set up a manual retraining schedule to run every week regardless of alerts.
E. Use Databricks SQL to create alerts on model performance and data drift metrics stored in Delta tables.

Answer: C,E

Explanation:
Databricks Lakehouse Monitoring stores model performance and data drift metrics in Delta tables, which can be monitored using Databricks SQL alerts. By creating alerts on F1 score degradation or significant feature drift and configuring those alerts to send webhook notifications, the engineer can automatically trigger a retraining job whenever predefined conditions are met, enabling event-driven, automated retraining aligned with MLOps best practices.

NEW QUESTION # 167
A Data Scientist is training a binary classification model using LogisticRegression in SparkML on a large dataset stored in a Delta table. After fitting the pipeline, they want to evaluate the model's performance using an appropriate metric and scalable method across the distributed test data using the SparkML API. Which model evaluation strategy will suit their needs?

A. Convert the DataFrame to RDD and use MulticlassMetrics.confusionMatrix() to calculate precision and recall manually, as this avoids the overhead of DataFrame operations in distributed environments.
B. Use MulticlassClassificationEvaluator with weightedPrecision metric since it provides more comprehensive evaluation than BinaryClassificationEvaluator for binary problems.
C. Use BinaryClassificationEvaluator with rawPredictionCo1 parameter, but first convert probability predictions to binary predictions using a UDF to ensure consistent evaluation across different Spark versions.
D. Use the BinaryClassificationEvaluator on the transformed test DataFrame and specify the appropriate metric.

Answer: D

Explanation:
BinaryClassificationEvaluator is the Spark ML-native, distributed evaluation API designed specifically for binary classification models. It operates directly on the transformed DataFrame produced by the pipeline and efficiently computes scalable metrics such as areaUnderROC or areaUnderPR without requiring data conversion or custom logic, making it the correct and efficient choice for large, distributed datasets.

NEW QUESTION # 168
A data scientist has developed and logged a scikit-learn random forest model model, and then they ended their Spark session and terminated their cluster. After starting a new cluster, they want to review the feature_importances_ of the original model object.
Which of the following lines of code can be used to restore the model object so that feature_importances_ is available?

A. client.list_artifacts(run_id)["feature-importances.csv"]
B. client.pyfunc.load_model(model_uri)
C. This can only be viewed in the MLflow Experiments UI
D. mlflow.sklearn.load_model(model_uri)
E. mlflow.load_model(model_uri)

Answer: E

NEW QUESTION # 169
In order to connect an MLflow Model Registry Webhook to a Databricks Job, the Job ID must be provided to the code block used to create the webhook. Which approach can be used to obtain a Databricks Job ID?

A. The Job ID field in the Jobs page in the UI
B. The Job ID field in the Job details section of the specific Job page in the UI
C. The Job ID field returned in a query using the Jobs API
D. All of these approaches

Answer: D

Explanation:
A Databricks Job ID can be obtained in multiple ways - it is displayed directly in the Jobs page, in the Job details section of a specific Job, and can also be retrieved programmatically through the Databricks Jobs API. Any of these methods can be used to supply the Job ID when configuring an MLflow Model Registry Webhook.
