A company applies cost allocation tags such as 'Project' and 'Environment' to its AWS resources. What is the primary purpose of these tags?
- ATo break down and organize billing data by category in cost reports
- BTo enforce IAM permissions on tagged resources
- CTo restrict which Regions a resource can be launched in
- DTo automatically apply Reserved Instance discounts to tagged resources
Show answer & explanationAnswer & explanation
Correct answer: A. To break down and organize billing data by category in cost reports
Cost allocation tags are key-value pairs applied to resources that appear in the AWS Cost and Usage Report and Cost Explorer, allowing organizations to categorize and track spending by project, department, or environment. They do not affect IAM permissions, RI application, or Region restrictions.
Why the other options are wrong
- B. Tags can be used in IAM policies for access control, but that is a separate use case from cost allocation.
- C. Region restrictions are controlled via IAM/SCP policies, not cost tags.
- D. RI discounts apply automatically based on instance attributes, not tags.
Cost Allocation Tags
Key-value labels applied to AWS resources that enable cost tracking and reporting by category such as project or department.
- Activated in the Billing console before appearing in reports
- Used in Cost Explorer and Cost and Usage Reports
- AWS-generated and user-defined tag types exist
Memory trick: Tag it to track it
