Microsoft Azure AI Fundamentals — Question 243

Which two actions are performed during the data ingestion and data preparation stage of an Azure Machine Learning process? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Answer options

• A. Calculate the accuracy of the model.
• B. Score test data by using the model.
• C. Combine multiple datasets.
• D. Use the model for real-time predictions.
• E. Remove records that have missing values.

Correct answer: C, E

Explanation

The correct answers are C and E because during data ingestion and preparation, datasets are often combined to create a comprehensive training set, and records with missing values are typically removed to ensure data quality. The other options refer to model evaluation and deployment stages rather than the ingestion and preparation phase.
