AWS Certified SysOps Administrator – Associate — Question 164

A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the computer. The overall usage is predictable. The amount of computer that is consumed in each Region varies, depending on the users' locations.

Which approach should the SysOps administrator use to optimize this workload?

Answer options

• A. Purchase Computer Savings Plans based on the usage during the past 30 days.
• B. Purchase Convertible Reserved Instances by calculating the usage baseline.
• C. Purchase EC2 Instance Savings Plans based on the usage during the past 30 days.
• D. Purchase Standard Reserved Instances by calculating the usage baseline.

Correct answer: A

Explanation

The correct answer is A because Compute Savings Plans offer flexibility and are ideal for variable workloads while providing savings based on past usage. Options B, C, and D involve Reserved Instances which are less flexible and may not align well with the predictable but varying usage across Regions, making them less suitable for this scenario.
