Databricks Certified Machine Learning Professional 認定 Databricks-Machine-Learning-Professional 試験問題 (Q150-Q155):

質問 # 150
A machine learning engineer has developed the following custom model class with preprocessing logic to combine two columns:

However, instances of this class are unable to compute predictions.
Which set of changes will update the class so predictions can be computed while continuing to apply the preprocessing logic?

A. Remove the self.rf_model = rf_model line from the fit method
B. Replace model_input.copy() with self.preprocess_input(model_input.copy()) in the preprocess_input method
C. Replace self.rf_model.predict(input) with self.predict(input) in the predict method
D. Replace model_input.copy() with self.preprocess_input(model_input.copy()) in the predict method

正解：D

解説：
The issue is that the predict() method does not apply the same preprocessing as the fit() method.
During training, the model uses preprocessed data (via self.preprocess_input()), but during prediction, it directly uses raw input. This mismatch causes prediction errors because the model expects preprocessed input.
By updating the predict() method to call self.preprocess_input(model_input.copy()), both training and prediction use consistent feature transformations, allowing predictions to be computed successfully.

質問 # 151
A machine learning engineer is in the process of implementing a feature drift monitoring solution.
They are planning to use the following steps:
1. Measure the distributions of each feature variable in the training
set
2. Deploy a model to production
3. Measure the distributions of each feature variable in inference
4. _______
Which action should be completed as Step #4?

A. Measure the latency of the model's prediction time
B. Run a statistical test to determine if there are changes in the feature variable distribution over time
C. Obtain the observed values (actual) feature values and compare to the predicted values
D. Retrain the model based on any new feature variables that have been added to the feature set

正解：B

解説：
The final step in a feature drift monitoring solution is to run a statistical test (e.g., Kolmogorov- Smirnov test) to determine whether the feature distributions in production have significantly diverged from those in the training set. This helps detect drift and maintain model reliability.

質問 # 152
A data scientist has developed a scikit-learn random forest model model, but they have not yet logged model with MLflow. They have created a model signature model_signature and a few example input records input_records. Which block of code can be used to log all of this information?

A. There is no way to log a model signature.
B. mlflow.sklearn.log_model(model, "model")
mlflow.log_signature(model_signature)
mlflow.log_input(input_records)
C.
D.

正解：C

解説：
The code block correctly uses the mlflow.sklearn.log_model() function with both signature and input_example parameters.
signature=model_signature defines the expected model input and output schema, ensuring reproducibility and validation during inference.
input_example=input_records provides a sample input that helps users understand the model's expected input format.

質問 # 153
A machine learning engineer has implemented a numeric drift monitoring solution by examining trends in the summary statistics of input variables. However, the engineer's stakeholders would like a more robust monitoring solution. Which of the following can provide a more robust drift monitoring solution for numeric feature variables?

A. None of these can provide more robust drift monitoring than summary statistics
B. Statistical tests
C. Oversampling
D. Correlations

正解：B

解説：
Statistical tests (such as the Kolmogorov-Smirnov test or Wasserstein distance) provide a more robust and quantitative method for detecting numeric feature drift compared to simple summary statistics. These tests compare the full distributions of features between datasets, making them more sensitive to subtle changes in data behavior over time.

質問 # 154
A Machine Learning Engineer has a large dataset with a customer_region column and wants to train separate models for each region, then generate predictions. They need to parallelize this group-specific model training process using Databricks and the Pandas Function API. Which approach will implement this solution?

A. Use mapInPandas() to apply the training function across all partitions without grouping.
B. Use groupBy("customer_region") and apply a training function with applyInPandas().
C. Use foreachBatch() to sequentially process each region's data.
D. Use collect() to gather all data and process regions using standard pandas groupby.

正解：B

解説：
The Pandas Function API supports parallel, group-specific processing by using groupBy on the grouping column and applyInPandas to execute a custom training function independently for each group. This enables separate models to be trained per region in parallel across the cluster, with each function invocation receiving only the data for its group.
