AWS Certified AI Practitioner (AIF-C01) — Question 266

A company wants to create an ML model to predict customer satisfaction. The company needs fully automated model tuning.

Which AWS service meets these requirements?

Answer options

• A. Amazon Personalize
• B. Amazon SageMaker
• C. Amazon Athena
• D. Amazon Comprehend

Correct answer: B

Explanation

Amazon SageMaker provides comprehensive capabilities for building, training, and deploying machine learning models, including automatic model tuning to find the best performing model. Amazon Personalize is designed specifically for recommendation systems, and Amazon Comprehend is a natural language processing service, neither of which support general-purpose custom ML model building and automated tuning. Amazon Athena is an interactive query service for analyzing data in Amazon S3 using SQL, not a machine learning service.
