Question

A company uses Amazon RDS to store transactional data. The company runs an RDS DB instance in a private subnet. A developer wrote an AWS Lambda function with default settings to insert, update, or delete data in the DB instance. The developer needs to give the Lambda function the ability to connect to the DB instance privately without using the public internet. Which combination of steps will meet this requirement with the LEAST operational overhead? (Choose two.)

Accepted Answer

Correct answer: C, D. The correct answer is C, D. Option C: Configure the Lambda function to run in the same subnet that the DB instance uses. Option D: Attach the same security group to the Lambda function and the DB instance. Include a self-referencing rule that allows access through the database port. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. AWS Config tracks resource configuration changes and evaluates compliance.
