AWS Certified Cloud Practitioner (CLF-C02) — Question 216

A company wants to migrate its PostgreSQL database to AWS. The company does not use the database frequently.

Which AWS service or resource will meet these requirements with the LEAST management overhead?

Answer options

• A. PostgreSQL on Amazon EC2
• B. Amazon RDS for PostgreSQL
• C. Amazon Aurora PostgreSQL-Compatible Edition
• D. Amazon Aurora Serverless

Correct answer: D

Explanation

Amazon Aurora Serverless is designed for applications with variable workloads, allowing automatic scaling and reducing management tasks. In contrast, PostgreSQL on Amazon EC2 requires manual setup and maintenance, while Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition still involve more management compared to Serverless options.
