Databricks Certified Machine Learning Professional Sample Questions (Q23-Q28):

NEW QUESTION # 23
A Machine Learning Engineer is working with a Spark DataFrame containing 100 million rows of retail transactions across thousands of stores. Each store requires its own demand forecasting model using the same scikit-learn pipeline. They want to train and apply these models in parallel for each store without collecting the data to the driver. Which approach will do this?

A. Use rdd.mapPartitions() to iterate through each store and apply the model logic in Python.
B. Use groupBy("store_id").applyInPandas() to train and apply the model per group using a Pandas UDF.
C. Use pyspark.pandas to call .groupby("store_id").apply() and train the model on each group.
D. Convert the DataFrame to a Pandas DataFrame using .toPandas() and loop through each store locally.

Answer: B

Explanation:
groupBy().applyInPandas() enables grouped Pandas UDFs that receive each store's data as a Pandas DataFrame on the executors. This allows training and applying a separate scikit-learn model per store in parallel without collecting data to the driver, making it the correct and scalable approach for large Spark DataFrames.

NEW QUESTION # 24
A Data Scientist is building a propensity model for an e-commerce start-up. The company maintains 7GB of historical data and receives about 5MB of new transaction data daily. The goal is to generate daily purchase predictions for all users by 7:00 AM each morning. As the start-up is in its early stages, the data scientist must prioritize a highly cost-efficient approach. Which approach should the Data Scientist take?

A. Use a multi-node compute and leverage distributed frameworks like SparkML to train the model.
The model can then be scheduled as a nightly batch job that runs on a multi-node compute.
B. Use a single-node compute to build a model with libraries like scikit-learn. The model can then be integrated into an always-on streaming pipeline, to ensure immediate processing of incoming data in order to meet the SLA.
C. Use a single-node compute to build a model with libraries like scikit-learn. The model can then be deployed as an always-on REST API so that users can query the API to get the predictions whenever they want.
D. Use a single-node memory compute to build a model with libraries like scikit-learn. The model can then be scheduled as a nightly batch job that runs on a single-node compute.

Answer: D

Explanation:
With only 7GB of historical data and a small daily increment (about 5MB), a single-node memory- optimized cluster can comfortably train and score using scikit-learn without the overhead and cost of distributed compute. Scheduling a nightly batch job is the most cost-efficient way to meet a fixed daily SLA (7:00 AM) because the compute can be started only for the job run and then terminated, avoiding the expense of always-on serving or streaming infrastructure.

NEW QUESTION # 25
Which of the following is a simple statistic to monitor for categorical feature drift?

A. Percentage of missing values
B. Mode, number of unique values, and percentage of missing values
C. None of these
D. Number of unique values
E. Mode

Answer: B

NEW QUESTION # 26
A machine learning engineer has developed a model and registered it using the FeatureStoreClient fs. The model has model URI model_uri. The engineer now needs to perform batch inference on customer-level Spark DataFrame spark_df, but it is missing a few of the static features that were used when training the model. The customer_id column is the primary key of spark_df and the training set used when training and logging the model.
Which of the following code blocks can be used to compute predictions for spark_df when the missing feature values can be found in the Feature Store by searching for features by customer_id?

A. df = fs.get_missing_features(spark_df, model_uri)
fs.score_batch(model_uri, df)
B. df = fs.get_missing_features(spark_df, model_uri)
fs.score_model(model_uri, df)
C. df = fs.get_missing_features(spark_df)
fs.score_batch(model_uri, df)
D. fs.score_model(model_uri, spark_df)
E. fs.score_batch(model_uri, spark_df)

Answer: E

NEW QUESTION # 27
