AWS Certified Cloud Practitioner — Question 595

Which database engine is compatible with Amazon RDS?

Answer options

• A. Apache Cassandra
• B. MongoDB
• C. Neo4j
• D. PostgreSQL

Correct answer: D

Explanation

Amazon RDS is a managed service designed specifically for relational databases, natively supporting engines like PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server. Other options such as Apache Cassandra, MongoDB, and Neo4j are NoSQL databases and are not supported as engines within Amazon RDS. Therefore, PostgreSQL is the only compatible database engine among the choices provided.
