CLF-C02 Question 47
Single answerYour company is running an application on an EC2 instance that is underutilized, with CPU usage consistently below 10%. To reduce costs without impacting performance, what would be the most appropriate rightsizing action?
- A
Switch to a smaller instance type with lower compute capacity.
- B
Upgrade to a larger instance type to improve performance.
- C
Terminate the instance and migrate to an on-premises server.
- D
Move the application to a dedicated host for better resource allocation.
Show answer and explanation
Correct answer: A
Explanation
Rightsizing involves analyzing resource usage and adjusting the instance type to better match the workload requirements. In this scenario, the instance is underutilized, so switching to a smaller instance size is the most appropriate action to reduce costs while maintaining performance.
- A. Correct.
Switching to a smaller instance type with lower compute capacity is a key rightsizing strategy to optimize costs when the current instance is underutilized.
- B. Incorrect.
Upgrading to a larger instance type would increase costs unnecessarily and is not appropriate for an underutilized instance.
- C. Incorrect.
Terminating the instance and migrating to an on-premises server is not aligned with the principles of rightsizing in the cloud, which focuses on optimizing cloud resources.
- D. Incorrect.
Moving the application to a dedicated host is typically used for compliance or licensing needs, not for cost optimization due to underutilization.
