Which databases are available on Amazon RDS?
(Choose two.)
Sybase
Microsoft SQL Server
IBM Db2
MongoDB
PostgreSQL
Explanations:
Sybase is not supported by Amazon RDS. RDS offers managed services for other databases but not for Sybase.
Microsoft SQL Server is available on Amazon RDS, allowing users to deploy, manage, and scale SQL Server databases easily.
IBM Db2 is not available on Amazon RDS. AWS does not provide managed services for Db2 within the RDS platform.
MongoDB is not supported by Amazon RDS. RDS is designed for relational databases and does not offer MongoDB as an option.
PostgreSQL is available on Amazon RDS, providing a fully managed PostgreSQL database service with features such as scaling and backups.
I compute that the answer is:
Microsoft SQL Server
