AWS Certified Cloud Practitioner (CLF-C02) — Question 506

Which AWS services can host PostgreSQL databases? (Choose two.)

Answer options

• A. Amazon S3
• B. Amazon Aurora
• C. Amazon EC2
• D. Amazon OpenSearch Service
• E. Amazon Elastic File System (Amazon EFS)

Correct answer: B, C

Explanation

Amazon Aurora is a fully managed relational database service that natively supports PostgreSQL compatibility. Amazon EC2 allows you to deploy and self-manage a PostgreSQL database on a virtual machine. Amazon S3, Amazon EFS, and Amazon OpenSearch Service are storage and search services that cannot directly host a relational database.
