AWS Certified SysOps Administrator – Associate — Question 223

A company has a core application that must run 24 hours a day, 7 days a week. The application uses Amazon EC2. AWS Fargate, and AWS Lambda. The company uses a combination of operating systems across different AWS Regions.

The company needs to maximize cost savings while committing to a pricing model that offers flexibility to make changes.

What should the company do to meet these requirements?

Answer options

• A. Purchase a Compute Savings Plan that is based on Savings Plans recommendations
• B. Purchase an EC2 Instance Savings Plan that covers the EC2 instance types and the Fargate and Lambda vCPU equivalents.
• C. Purchase a Reserved Instance for the instance types, operating systems, Region, and tenancy,
• D. Use EC2 Spot Instances that match the type and size of existing instances that run in each Region.

Correct answer: A

Explanation

The correct choice is A, as a Compute Savings Plan provides flexibility across various services and allows for cost savings without locking into specific resources. Option B, while beneficial for EC2 and related services, does not offer the same level of adaptability. Option C restricts the company to specific instance types and configurations, which might not accommodate future changes. Option D involves using Spot Instances, which are not suitable for applications that require 24/7 uptime due to their potential for interruption.
