AWS Certified Cloud Practitioner — Question 627

A company needs to optimize the cost of its compute resources.

Which type of workload should the company run on Amazon EC2 Reserved Instances?

Answer options

• A. A steady-state workload that requires a particular EC2 instance configuration for a long period of time
• B. A short-term workload that can be interrupted
• C. A steady-state workload that does not require a long-term commitment
• D. A short-term workload that cannot be interrupted

Correct answer: A

Explanation

Amazon EC2 Reserved Instances provide a significant discount compared to On-Demand pricing in exchange for a commitment of one or three years, making them ideal for predictable, steady-state workloads. Short-term workloads that can tolerate interruptions are best suited for Spot Instances, while short-term, non-interruptible workloads should use On-Demand Instances.
