B - https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-run-lambda-schedule.html + https://aws.amazon.com/blogs/mt/using-aws-lambda-to-decommission-products-provisioned-from-an-aws-service-catalog-portfolio/ Ideally you want to delete the Stack, not just the EC2 and RDS instances. Persistant EBS volumes and snapshots may still exist that can incurr cost.

Correct Answer: B Option B provides an operationally efficient approach. By using AWS CloudFormation, each developer can easily create an identical development environment from a template. Scheduling a nightly EventBridge rule to invoke a Lambda function that deletes the CloudFormation stacks is efficient because it ensures all resources (EC2 instances, RDS instances, etc.) are automatically deleted every night, reducing costs without requiring additional manual work. Other Options: Option A stops processes to reduce CPU usage but does not terminate resources, meaning costs associated with instances and RDS would still accrue. Option C and Option D require developers to manually provision environments with CLI commands, which is less efficient than CloudFormation templates. Additionally, Option C does not delete CloudFormation stacks, so it’s less organized for ongoing, consistent setup and teardown.

it should be C, keyword is "Terminate all resources", not delete stack only

B for sure!

This solution allows each developer to easily create an identical development environment when they need it by using the CloudFormation template. AWS CloudFormation templates are a great way to version and standardize infrastructure, and can be used to create and manage a collection of related AWS resources. The EventBridge rule scheduled to trigger the Lambda function ensures that all resources associated with each CloudFormation stack are deleted every night, minimizing unnecessary costs.

B is correct

B is correct. It cannot possibly be "C" because the question stipulates the environments must be identical. Handing over access to run CLI commands will not result in identical environments, but provisioning them in CloudFormation will accomplish that.
