AWS Certified Cloud Practitioner (CLF-C02) — Question 250

A company needs Amazon EC2 instances for a workload that can tolerate interruptions.

Which EC2 instance purchasing option meets this requirement with the LARGEST discount compared to On-Demand prices?

Answer options

• A. Spot Instances
• B. Convertible Reserved Instances
• C. Standard Reserved Instances
• D. Dedicated Hosts

Correct answer: A

Explanation

Spot Instances allow users to bid on unused EC2 capacity, often providing substantial discounts compared to On-Demand prices. In contrast, Convertible and Standard Reserved Instances require a commitment for a longer term and provide savings, but not as significant as Spot Instances. Dedicated Hosts are typically used for specific compliance or licensing requirements and do not offer the same level of cost savings.
