AWS Certified Cloud Practitioner (CLF-C02) — Question 53
An online gaming company needs to choose a purchasing option to run its Amazon EC2 instances for 1 year. The web traffic is consistent, and any increases in traffic are predictable. The EC2 instances must be online and available without any disruption.
Which EC2 instance purchasing option will meet these requirements MOST cost-effectively?
Answer options
- A. On-Demand Instances
- B. Reserved Instances
- C. Spot Instances
- D. Spot Fleet
Correct answer: B
Explanation
Reserved Instances are the most cost-effective option for predictable and consistent web traffic, as they provide a significant discount for committing to a one-year term. On-Demand Instances, while flexible, do not offer the same cost savings for long-term usage. Spot Instances and Spot Fleet are less suitable in this scenario because they may not guarantee availability and could lead to disruptions during peak traffic times.
