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

NEW QUESTION # 165
A machine learning engineer wants to deploy a model for real-time serving using MLflow Model Serving. For the model, the machine learning engineer currently has one model version in each of the stages in the MLflow Model Registry. The engineer wants to know which model versions can be queried once Model Serving is enabled for the model. Which of the following lists all of the MLflow Model Registry stages whose model versions are automatically deployed with Model Serving?

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

Answer: B

NEW QUESTION # 166
A machine learning engineer is attempting to create a webhook that will trigger a Databricks Job job_id when a model version for model model transitions into any MLflow Model Registry stage.
They have the following incomplete code block:

Which of the following lines of code can be used to fill in the blank so that the code block accomplishes the task?

A. "MODEL_VERSION_CREATED"
B. "MODEL_VERSION_TRANSITIONED_STAGE"
C. "MODEL_VERSION_TRANSITIONED_TO_STAGING", "MODEL_VERSION_TRANSITIONED_TO_PRODUCTION"
D. "MODEL_VERSION_TRANSITIONED_TO_STAGING"
E. "MODEL_VERSION_TRANSITIONED_TO_PRODUCTION"

Answer: D

NEW QUESTION # 167
A Data Scientist is developing a model training pipeline on Databricks and needs to track custom performance metrics during training. They want to log a custom evaluation score (team_score), a single hyperparameter, and a confusion matrix plot as part of their MLflow experiment. Which code snippet correctly logs all three types of information in MLflow?

A. mlflow.log_metric({"team_score": 0.92})
mlflow.log_param(["max_depth", 5])
mlflow.log_file("confusion_matrix.png")
B. mlflow.log_param("max_depth", "5")
mlflow.log_metric("team_score", "0.92")
mlflow.log_artifact("confusion_matrix.png")
C. mlflow.log_param("max_depth", 5)
mlflow.log_metric("team_score", 0.92)
mlflow.log_artifact("confusion_matrix.png")
D. mlflow.log_param("max_depth", 5)
mlflow.log_metric("team_score", 0.92)
mlflow.log_artifact(open("confusion_matrix.png"))

Answer: C

Explanation:
This snippet correctly uses MLflow's APIs to log each item in its expected form: a single hyperparameter with log_param, a numeric custom metric with log_metric, and a file-based artifact such as a confusion matrix image by passing its file path to log_artifact. This is the standard and correct way to track parameters, metrics, and artifacts in an MLflow experiment.

NEW QUESTION # 168
A Data Scientist has trained a regression model using Spark's MLlib to predict housing prices.
The model needs to be evaluated to determine how well it predicts on a testing dataset. The Data Scientist wants to use a standard regression metric for the evaluation. They also want to evaluate the model with the least processing overhead required. Which approach will suit their needs?

A. Convert the testing dataset to a pandas DataFrame and use scikit-learn's root_mean_squared_error function to calculate the root mean squared error on the testing dataset.
B. Use the MLlib's RegressionEvaluator with the metricName set to rmse to calculate root mean squared error on the testing dataset.
C. Implement a Spark UDF to calculate the root mean squared error for each row in the testing dataset and aggregate these values to obtain the overall RMSE score.
D. Use the MLlib's RankingEvaluator with the metricName set to rmse to calculate root mean squared error on the testing dataset.

Answer: B

Explanation:
RegressionEvaluator is the Spark ML-native, distributed evaluation API for regression models.
Setting metricName to rmse computes root mean squared error directly on the distributed test DataFrame with minimal overhead, avoiding unnecessary data movement or custom computation logic.

NEW QUESTION # 169
A Machine Learning Engineer is building a Databricks ML pipeline to predict customer churn. The pipeline needs to include automated feature engineering, model training, evaluation, and deployment to a REST API endpoint using MLflow. What is the primary goal of an integration test for this pipeline?

A. To ensure that the pipeline's performance meets latency and scalability requirements under simulated production loads
B. To monitor the model's performance after it has been deployed into the production environment
C. To ensure the pipeline runs with all components working together and data flowing correctly between stages
D. To verify that the pipeline can process a variety of data formats, even if some stages are skipped or bypassed

Answer: C

Explanation:
The primary purpose of an integration test is to validate that all components of the ML pipeline work together as expected. This includes confirming that data flows correctly through feature engineering, training, evaluation, and deployment steps, ensuring the end-to-end pipeline functions properly as a cohesive system.
