AWS Certified Cloud Practitioner — Question 785

Which AWS service provides a relational database management system that is fully compatible with MySQL and PostgreSQL?

Answer options

• A. Amazon DynamoDB
• B. Amazon Aurora
• C. Amazon Neptune
• D. Amazon Athena

Correct answer: B

Explanation

Amazon Aurora is a cloud-native relational database service that provides full compatibility with MySQL and PostgreSQL. In contrast, Amazon DynamoDB is a NoSQL database, Amazon Neptune is a graph database, and Amazon Athena is an interactive query service designed for analyzing data in Amazon S3 rather than a relational database management system.
