AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 380

Question

A company is migrating its on-premises workload to the AWS Cloud. The company already uses several Amazon EC2 instances and Amazon RDS DB instances. The company wants a solution that automatically starts and stops the EC2 instances and DB instances outside of business hours. The solution must minimize cost and infrastructure maintenance. Which solution will meet these requirements?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create an AWS Lambda function that will start and stop the EC2 instances and DB instances. Configure Amazon EventBridge to invoke the Lambda function on a schedule. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures. This option delivers the requirement at the lowest cost.
