Oracle Cloud Infrastructure 2021 Architect Professional — Question 10

You want to train a classification model with MySQL HeatWave AutoML. Which two are requirements of the training data set? (Choose two.)

Answer options

• A. The target column must be numeric.
• B. The target column and all feature columns must be stored in a single table.
• C. All feature columns must be numeric.
• D. There must be at least two feature columns.
• E. The target column must have at least two distinct values.

Correct answer: B, E

Explanation

The correct answers are B and E because the target column and all feature columns must indeed be in the same table for proper training, and the target must have at least two distinct values to enable classification. Options A and C are incorrect as the target and feature columns do not need to be exclusively numeric, and D is not necessary as having two feature columns is not a strict requirement.
