C, D is correct. Not only java, but also python, node.js would require the appropriate driver package being included / installed in the environment.

Not sure what "endpoint" A is referring to, but you do need driver and connection string to access database, even though in most cases, you don't have to manually "download and include"

To connect to the database, add the appropriate driver JAR file to your application, load the driver class in your code, and create a connection object with the environment properties provided by Elastic Beanstalk. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-rds.html

The link you provided is applicable to Java. The question didn't mention specifically for Java. Therefore irrelevant. I think it's AD. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.RDS.html

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.db.html "Elastic Beanstalk provides integration with Amazon Relational Database Service (Amazon RDS). You can use Elastic Beanstalk to add a MySQL, PostgreSQL, Oracle, or SQL Server database to an existing environment or a new one when you create it. When you add a database instance, Elastic Beanstalk provides the connection information to your application. It does this by setting the environment properties for the database hostname, port, user name, password, and database name."

Ans: A, D https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.RDS.html After you launch your database instance and configure security groups, you can pass the connection information, such as the endpoint and password, to your application by using environment properties. This is the same mechanism that Elastic Beanstalk uses in the background when you run a database instance in your environment.
