Databricks Certified Machine Learning Professional Sample Questions (Q82-Q87):

NEW QUESTION # 82
Which of the following is a benefit of logging a model signature with an MLflow model?

A. The schema of input data can be validated when serving models
B. The model can be deployed using real-time serving tools
C. The model will have a unique identifier in the MLflow experiment
D. The model will be secured by the user that developed it
E. The schema of input data will be converted to match the signature

Answer: E

NEW QUESTION # 83
A data scientist wants to remove the star_rating column from the Delta table at the location path.
To do this, they need to load in data and drop the star_rating column. Which of the following code blocks accomplishes this task?

A. Delta tables cannot be modified
B. spark.read.format("delta").load(path).drop("star_rating")
C. spark.read.table(path).drop("star_rating")
D. spark.read.format("delta").table(path).drop("star_rating")
E. spark.sql("SELECT * EXCEPT star_rating FROM path")

Answer: C

NEW QUESTION # 84
Which of the following can be used to compare the relative prevalence of specific values in a single categorical variable between two datasets or time periods?

A. Mode
B. Jensen-Shannon distance
C. Contingency tables
D. Number of unique values

Answer: C

Explanation:
Contingency tables (also known as cross-tabulations) display the frequency distribution of categorical variables, allowing comparison of how specific category values occur across two datasets or time periods. This makes them effective for identifying categorical feature drift or shifts in value prevalence.

NEW QUESTION # 85
A Machine Learning Engineer is considering moving their functions and unit tests from notebooks into separate Python files (e.g., modules and test scripts) to take advantage of the numerous benefits of this approach like automated execution, code reusability, and version control. Which challenge should the engineer consider with this approach?

A. It makes functions harder to import and reuse across different notebooks.
B. This change would prevent the use of any non-Python environments like Scala.
C. Managing a more complex project structure can be harder to maintain and navigate.
D. Separating code and tests often leads to decreased reliability and poor code quality.

Answer: C

Explanation:
Moving code and unit tests into separate Python modules introduces a more structured project layout, which can increase complexity. Engineers must manage directories, dependencies, and imports carefully, making the project slightly harder to navigate and maintain compared to simple notebook-based workflows, especially for teams new to this structure.

NEW QUESTION # 86
A machine learning engineer is migrating a machine learning pipeline to use Databricks Machine Learning. They have programmatically identified the best run from an MLflow Experiment and stored its URI in the model_uri variable and its Run ID in the run_id variable. They have also determined that the model was logged with the name "model". Now, the machine learning engineer wants to register that model in the MLflow Model Registry with the name "best_model".
Which line of code can they use to register the model to the MLflow Model Registry?

A. mlflow.register_model(model_uri, "model")
B. mlflow.register_model(run_id, "best_model")
C. mlflow.register_model(f"runs:/{run_id}/model")
D. mlflow.register_model(f"runs:/{run_id}/best_model", "model")
E. mlflow.register_model(model_uri, "best_model")

Answer: E
