Question 19
Content Domain 3: ModelingA machine learning practitioner must choose a compute platform for model training. Based on the available guidance, which platform choice is explicitly within scope for this decision?
Correct answer: D
Explanation
When selecting a compute platform for model training, the decision is framed as choosing between Spark and non-Spark platforms. — Choose appropriate compute platforms (Spark or non-Spark).
Why each option is right or wrong
A. Choose only among GPU memory sizes
The stated decision is between Spark and non-Spark platforms for compute selection.
B. Choose only among supervised learning algorithms
The guidance addresses compute platform selection, not algorithm family selection.
C. Choose only among data labeling workflows
The topic is model-training compute platforms, not data preparation workflow choices.
D. Choose between Spark and non-Spark compute platforms
The source explicitly defines the compute-platform decision as "Choose appropriate compute platforms (Spark or non-Spark)." Therefore, the in-scope choice is between Spark and non-Spark platforms.
