AWS Certified Cloud Practitioner (CLF-C02) — Question 190

Which Amazon EC2 instance pricing model can provide discounts of up to 90%?

Answer options

• A. Reserved Instances
• B. On-Demand
• C. Dedicated Hosts
• D. Spot Instances

Correct answer: D

Explanation

The correct answer is D, Spot Instances, which allow users to bid on unused EC2 capacity and can provide significant savings. Reserved Instances offer savings but typically do not reach 90%, while On-Demand pricing charges the full price for instances used without any long-term commitment. Dedicated Hosts provide a physical server for use but do not offer the same level of discount as Spot Instances.
