AWS Certified Database – Specialty — Question 146

A company is running its customer feedback application on Amazon Aurora MySQL. The company runs a report every day to extract customer feedback, and a team reads the feedback to determine if the customer comments are positive or negative. It sometimes takes days before the company can contact unhappy customers and take corrective measures. The company wants to use machine learning to automate this workflow.
Which solution meets this requirement with the LEAST amount of effort?

Answer options

• A. Export the Aurora MySQL database to Amazon S3 by using AWS Database Migration Service (AWS DMS). Use Amazon Comprehend to run sentiment analysis on the exported files.
• B. Export the Aurora MySQL database to Amazon S3 by using AWS Database Migration Service (AWS DMS). Use Amazon SageMaker to run sentiment analysis on the exported files.
• C. Set up Aurora native integration with Amazon Comprehend. Use SQL functions to extract sentiment analysis.
• D. Set up Aurora native integration with Amazon SageMaker. Use SQL functions to extract sentiment analysis.

Correct answer: C

Explanation

Option C is correct because it allows for direct integration between Aurora and Amazon Comprehend, enabling sentiment analysis using SQL functions without the need for data export, making it the least effort solution. Options A and B require exporting the data to Amazon S3, which adds complexity and effort. Option D involves SageMaker, which is more complicated than using Comprehend for this specific task.
