You are a developer for a company that is planning on using the AWS RDS service. Your Database administrator spins up a new MySQL RDS Instance in AWS. You now need to connect to that instance. How can you achieve this? Choose 2 answers from the options given below.

Answer options:

A.Use the DescribeDBInstances API and get the endpoint for the database instance.
B.Use the DescribeDBInstances API and get the IP address for the database instance.
C.Request an endpoint for the instance from the Database Administrator.
D.Request the IP address of the instance from the Database Administrator.

Answer – A and C
The AWS Documentation mentions the following.
Before you can connect to a DB instance running the MySQL database engine, you must create a DB instance. For information, see Creating a DB Instance Running the MySQL Database Engine. Once Amazon RDS provisions your DB instance, you can use any standard MySQL client application or utility to connect to the instance. In the connection string, you specify the DNS address from the DB instance endpoint as the host parameter and specify the port number from the DB instance endpoint as the port parameter.
You can use the AWS Management Console, the AWS CLI describe-db-instances command, or the Amazon RDS API DescribeDBInstances action to list the details of an Amazon RDS DB instance, including its endpoint.
Options B and D are incorrect since even the endpoints resolve to IP addresses and the IP addresses can be used to connect to the database, this is not a recommended option because the underlying IP address could change during failover.
