AWS Certified Machine Learning – Specialty — Question 29

A Machine Learning Specialist is working with a large company to leverage machine learning within its products. The company wants to group its customers into categories based on which customers will and will not churn within the next 6 months. The company has labeled the data available to the Specialist.
Which machine learning model type should the Specialist use to accomplish this task?

Answer options

• A. Linear regression
• B. Classification
• C. Clustering
• D. Reinforcement learning

Correct answer: B

Explanation

The correct answer is B, Classification, as it is used to predict categorical outcomes based on labeled data, which is exactly the requirement for identifying churn. Options A (Linear regression) is inappropriate since it predicts continuous values, C (Clustering) is not suitable because it deals with unlabeled data, and D (Reinforcement learning) is focused on decision-making in dynamic environments rather than classification tasks.
