AWS Certified Cloud Practitioner (CLF-C02) — Question 156

A company plans to migrate its application to AWS and run the application on Amazon EC2 instances. The application will have continuous usage for 1 year.

Which EC2 instance purchasing option will meet these requirements MOST cost-effectively?

Answer options

Correct answer: A

Explanation

Reserved Instances provide a significant cost saving for long-term, continuous usage, such as the 1-year period mentioned. Spot Instances are not suitable for consistent workloads due to their variable availability, while On-Demand Instances offer flexibility but at a higher cost for long-term use. Dedicated Hosts are used for compliance purposes and are typically more expensive than Reserved Instances.
