AWS Certified Cloud Practitioner (CLF-C02) — Question 409

Which recommendation can AWS Cost Explorer provide to help reduce cost?

Answer options

• A. Use a specific database engine.
• B. Change the programming language for an application.
• C. Deploy a specific operating system.
• D. Terminate an idle instance.

Correct answer: D

Explanation

AWS Cost Explorer provides resource optimization recommendations, such as identifying and suggesting the termination of idle or underutilized Amazon EC2 instances to reduce costs. It does not provide recommendations related to application code, operating systems, or database engine selections, as these are architectural and software configurations outside its cost-optimization scope.
