AWS Certified Machine Learning – Specialty — Question 41

A company is running a machine learning prediction service that generates 100 TB of predictions every day. A Machine Learning Specialist must generate a visualization of the daily precision-recall curve from the predictions, and forward a read-only version to the Business team.
Which solution requires the LEAST coding effort?

Answer options

• A. Run a daily Amazon EMR workflow to generate precision-recall data, and save the results in Amazon S3. Give the Business team read-only access to S3.
• B. Generate daily precision-recall data in Amazon QuickSight, and publish the results in a dashboard shared with the Business team.
• C. Run a daily Amazon EMR workflow to generate precision-recall data, and save the results in Amazon S3. Visualize the arrays in Amazon QuickSight, and publish them in a dashboard shared with the Business team.
• D. Generate daily precision-recall data in Amazon ES, and publish the results in a dashboard shared with the Business team.

Correct answer: C

Explanation

Option C is the correct answer because it combines the data generation and visualization processes in a streamlined manner, minimizing coding needs. Options A and D do not include visualization directly in the workflow, which adds complexity, while option B lacks the data generation step required for a complete solution.
