AWS Certified Cloud Practitioner (CLF-C02) — Question 528

A company wants to use Amazon EC2 instances for a stable production workload that will run for 1 year.

Which instance purchasing option meets these requirements MOST cost-effectively?

Answer options

Correct answer: B

Explanation

Reserved Instances are the most cost-effective choice for stable, predictable workloads with a known duration of 1 or 3 years, offering significant discounts compared to On-Demand pricing. Spot Instances are unsuitable for production workloads due to the risk of unexpected termination, while On-Demand Instances do not offer commitment-based savings. Dedicated Hosts are designed for specific compliance and licensing needs and are not the most economical option for standard workloads.
