Which types of RDS databases are currently available?

  1. Aurora, MySQL, MSSQL, Cassandra

  2. Postgres, Cassandra, MongoDB, Aurora

  3. Oracle, MSSQL, MySQL, Cassandra

  4. Oracle, MSSQL, MySQL, Postgres

The correct answer is: Oracle, MSSQL, MySQL, Postgres

The correct answer identifies the types of RDS (Relational Database Service) databases that are officially supported by AWS. Amazon RDS offers a variety of relational database engines, and among these, Oracle, Microsoft SQL Server (MSSQL), MySQL, and PostgreSQL (Postgres) are included. Amazon RDS simplifies the management of these databases by providing automated backups, patching, scaling, and high availability, which are critical features for applications requiring reliable data storage and retrieval. Other options inaccurately include non-relational database services, such as Cassandra and MongoDB, which are not offered as part of Amazon RDS. These databases operate under different paradigms compared to the other options listed and typically require different management approaches. Thus, only the databases listed in the correct answer align with the relational offerings of Amazon RDS.
