Databricks Certified Machine Learning Professional Sample Questions (Q37-Q42):

NEW QUESTION # 37
A machine learning engineer has developed a random forest model using scikit-learn, logged the model using MLflow as random_forest_model, and stored its run ID in the run_id Python variable.
They now want to deploy that model by performing batch inference on a Spark DataFrame spark_df. Which of the following code blocks can they use to create a function called predict that they can use to complete the task?

Answer: B


NEW QUESTION # 38
A data scientist is utilizing MLflow to track their machine learning experiments. After completing a series of runs for the experiment with experiment ID exp_id, the data scientist wants to programmatically work with the experiment run data in a Spark DataFrame. They have an active MLflow Client client and an active Spark session spark. Which of the following lines of code can be used to obtain run-level results for exp_id in a Spark DataFrame?

Answer: C


NEW QUESTION # 39
A Data Scientist has been performing hyperparameter tuning using Ray Tune with grid search.
After team discussions, they decide to switch to Bayesian optimization to more efficiently explore the parameter space.
Their current code is:

How can they implement this change?

Answer: B

Explanation:
Bayesian optimization in Ray Tune requires defining a continuous or discrete search space (such as tune.randint) and explicitly configuring a Bayesian search algorithm. Using tune.randint defines a probabilistic parameter domain, and setting search_alg to BayesOptSearch enables Bayesian optimization to efficiently explore the space based on past trial results, rather than exhaustively enumerating all values as in grid search.


NEW QUESTION # 40
A Machine Learning Engineer wants to deploy a new change to their existing model training pipeline for a social media app. Currently, they use the Databricks Feature Store to create a training set to train their LightGBM model, which is then used in a Pandas UDF for batch inference to suggest potential friends to users. They have updated the feature engineering pipeline to include an additional feature function, which now computes the number of mutual friends a user has. Which test should they add to quickly inform them if something has broken in the test environment?

Answer: D

Explanation:
A unit test targeting the new feature function provides the fastest and most reliable signal that the recent change behaves correctly. By validating the mutual friends calculation on a controlled, fake dataset in the test environment, the engineer can quickly detect logic errors without the cost, risk, or latency of running full pipeline or production-based tests.


NEW QUESTION # 41
Why is Apache Spark useful for machine learning training?

Answer: C

Explanation:
Spark processes large distributed datasets efficiently.
