Databricks Certified Machine Learning Professional Sample Questions (Q57-Q62):

NEW QUESTION # 57
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_param("max_depth", "5")
mlflow.log_metric("team_score", "0.92")
mlflow.log_artifact("confusion_matrix.png")
B. mlflow.log_param("max_depth", 5)
mlflow.log_metric("team_score", 0.92)
mlflow.log_artifact(open("confusion_matrix.png"))
C. mlflow.log_metric({"team_score": 0.92})
mlflow.log_param(["max_depth", 5])
mlflow.log_file("confusion_matrix.png")
D. mlflow.log_param("max_depth", 5)
mlflow.log_metric("team_score", 0.92)
mlflow.log_artifact("confusion_matrix.png")

Answer: D

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 # 58
A machine learning engineer needs to deliver predictions of a machine learning model in real-time. However, the feature values needed for computing the predictions are available one week before the query time.
Which of the following is a benefit of using a batch serving deployment in this scenario rather than a real-time serving deployment where predictions are computed at query time?

A. There is no advantage to using batch serving deployments over real-time serving deployments
B. Batch serving has built-in capabilities in Databricks Machine Learning
C. Querying stored predictions can be faster than computing predictions in real-time
D. Computing predictions in real-time provides more up-to-date results
E. Testing is not possible in real-time serving deployments

Answer: B

NEW QUESTION # 59
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 the BinaryClassificationEvaluator on the transformed test DataFrame and specify the appropriate metric.
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 MulticlassClassificationEvaluator with weightedPrecision metric since it provides more comprehensive evaluation than BinaryClassificationEvaluator for binary problems.

Answer: B

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 # 60
A machine learning engineer is monitoring categorical input variables for a production machine learning application. The engineer believes that missing values are becoming more prevalent in more recent data for a particular value in one of the categorical input variables.
Which of the following tools can the machine learning engineer use to assess their theory?

A. One-way Chi-squared Test
B. Jenson-Shannon distance
C. None of these
D. Two-way Chi-squared Test
E. Kolmogorov-Smirnov (KS) test

Answer: A

NEW QUESTION # 61
Which MLflow feature helps reproduce training runs?

A. Model Serving
B. MLflow Projects
C. MLflow Tracking
D. Delta Sharing

Answer: C

Explanation:
Tracking logs:
parameters
code version
metrics
artifacts
making runs reproducible.
