AWS Certified SysOps Administrator – Associate (legacy) — Question 861

A SysOps Administrator has been asked to configure user-defined cost allocation tags for a new AWS account. The company is using AWS Organizations for account management.
What should the Administrator do to enable user-defined cost allocation tags?

Answer options

• A. Log in to the AWS Billing and Cost Management console of the new account, and use the Cost Allocation Tags manager to create the new user-defined cost allocation tags.
• B. Log in to the AWS Billing and Cost Management console of the payer account, and use Cost Allocation Tags manager to create the new user-defined cost allocation tags.
• C. Log in to the AWS Management Console of the new account, use the Tag Editor to create the new user-defined tags, then use the Cost Allocation Tags manager in the new account to mark the tags as cost allocation tags.
• D. Log in to the AWS Management Console of the new account, use the Tag Editor to create the new user-defined tags, then use the Cost Allocation Tags manager in the payer account to mark the tags as cost allocation tags.

Correct answer: B

Explanation

In an AWS Organizations setup, cost allocation tags must be activated and managed from the consolidated billing management (payer) account, not from individual member accounts. Once resources in member accounts are tagged, the administrator must log into the payer account's Billing and Cost Management console to activate those tags for cost tracking. Any attempts to enable or manage cost allocation tags directly within a member account's billing console will not work.
