Content Domain 4: Billing, Pricing, and Support

A company runs an uninterruptible Amazon EC2 workload on AWS 24 hours a day, 7 days a week. The company will require the same instance family and instance type to run the workload for the next 12 months.

Which combination of purchasing options should the company choose to MOST optimize costs?

Choose two
  • A Standard Reserved Instance
  • B Convertible Reserved Instance
  • C Compute Savings Plan
  • D Spot Instance
  • E All Upfront payment
Explanation

For a 24/7 predictable workload running for exactly 12 months with the same instance family and type, Standard Reserved Instances provide significant cost savings over On-Demand. Choosing the All Upfront payment option further maximizes the discount compared to partial upfront or no upfront payment plans. Spot Instances would not work for an uninterruptible workload.
