AWS Certified Cloud Practitioner (CLF-C02) — Question 634
A company wants a cost-effective option when running its applications in an Amazon EC2 instance for short time periods. The applications can be interrupted.
Which EC2 instance type will meet these requirements?
Answer options
- A. Spot Instances
- B. On-Demand Instances
- C. Reserved Instances
- D. Dedicated Instances
Correct answer: A
Explanation
Amazon EC2 Spot Instances allow you to utilize spare AWS capacity at steep discounts, making them the most cost-effective choice for workloads that can tolerate being interrupted. On-Demand and Reserved Instances are designed for continuous or predictable workloads and do not offer the same level of short-term savings, while Dedicated Instances are premium physical servers meant for compliance or licensing needs.
