AWS Certified SysOps Administrator – Associate (legacy) — Question 718

A SysOps Administrator needs to report on Amazon EC2 instance cost by both project and environment (production, staging, development).
Which action would impact the operations team the LEAST?

Answer options

• A. For each project and environment, create a new AWS account and link them to the master payer for unified management and billing
• B. Use AWS Organizations to create a new organization for each project, then for each environment use a separate linked AWS account
• C. Implement cost allocation tagging in the Billing and Cost Management console to implement tags to identify resources by project and environment
• D. Add the project and environment information to the instance metadata so that the values can be queried and rolled up into reports

Correct answer: C

Explanation

Using cost allocation tags is the most efficient and least disruptive method to track resources by project and environment directly within the Billing and Cost Management console. Creating multiple new AWS accounts or organizations would introduce massive administrative overhead for the operations team. Storing this data in instance metadata does not natively feed into AWS billing reports, making it ineffective for cost tracking.
