AWS Certified Cloud Practitioner — Question 827

A company is expecting a short-term spike in internet traffic for its application. During the traffic increase, the application cannot be interrupted. The company also needs to minimize cost and maximize flexibility.

Which Amazon EC2 instance type should the company use to meet these requirements?

Answer options

Correct answer: A

Explanation

On-Demand Instances are ideal for short-term, unpredictable workloads because they offer high flexibility with no long-term commitment and guarantee no interruptions. Spot Instances are not suitable because they can be reclaimed by AWS with short notice, which violates the no-interruption requirement. Reserved Instances require a 1- or 3-year commitment, making them cost-ineffective for temporary spikes, while Dedicated Hosts are designed for specific licensing and compliance needs rather than flexible, low-cost scaling.
