2 questions from the DATABRICKS-CERTIFIED-MACHINE-LEARNING-PROFESSIONAL practice set, with the answer and explanation.
- Question 1A data scientist wants every run in a shared experiment to record scikit-learn hyperparameters and evaluation metrics without writing explicit log calls. Which MLflow feature provides this?
- A.mlflow.autolog()
- B.mlflow.register_model()
- C.mlflow.pyfunc.spark_udf()
- D.mlflow.set_tag()
Show answerHide answer
Correct answer:
- A.mlflow.autolog()
Explanation
mlflow.autolog() instruments supported libraries such as scikit-learn so parameters, metrics and the fitted model are logged to the active run automatically. mlflow.register_model() only adds an existing model to the registry, and mlflow.set_tag() writes one manual tag, so neither captures training metadata. spark_udf is used to score with a logged model, not to log it. - A.
- Question 2Calling mlflow.start_run(nested=True) inside an active parent run creates a child run grouped under that parent, which suits logging each trial of a hyperparameter search.
- A.True
- B.False
Show answerHide answer
Correct answer:
- A.True
Explanation
Nested runs let each trial of a tuning job appear as a child of one parent run, which keeps the experiment table organized. Starting a run with nested=True while no parent run is active is the case that needs care, so the statement as written describes the intended pattern correctly. - A.
