AWS Certified Cloud Practitioner (CLF-C02) — Question 407

A company uses Amazon EC2 instances to run its application. The application needs to be available and running continuously for three or more years.

What type of EC2 instance should the company purchase for a discount on the EC2 pricing?

Answer options

Correct answer: A

Explanation

Reserved Instances offer a significant discount compared to On-Demand Instances when committing to a one-year or three-year term, making them ideal for continuous, long-term workloads. Spot Instances are not suitable because they can be interrupted by AWS, and On-Demand Instances do not provide long-term commitment discounts.
