Difficulty: EasyCost Allocation Tags and Resource Tagging Strategies

A SysOps Administrator in a multi-account organization wants to organize monthly AWS spending by project using the tag key `ProjectName`. The administrator has successfully applied this tag to all Amazon EC2 instances within the member accounts. However, when generating a monthly cost report in AWS Cost Explorer from the management account, the administrator cannot find `ProjectName` in the tag filtering options. Which action must the administrator take to ensure the `ProjectName` tag is available in Cost Explorer?

  1. Activate the `ProjectName` tag as a cost allocation tag in the AWS Billing and Cost Management console of the management account.Answer
  2. B
    Wait for the monthly billing cycle to complete, as user-defined tags are automatically activated and processed only at the end of each billing period.
  3. C
    Enable detailed monitoring on all EC2 instances to allow the Cost Explorer API to retrieve metadata tags.
  4. D
    Attach an IAM policy to the member accounts allowing the `aws:RequestTag` permission for the EC2 instances.

Answer

Activate the `ProjectName` tag as a cost allocation tag in the AWS Billing and Cost Management console of the management account.
The correct action is to activate the `ProjectName` tag as a cost allocation tag in the AWS Billing and Cost Management console of the management account. Applying a tag to resources only creates the metadata on the resource; to use it for tracking costs and filtering in AWS Cost Explorer, it must be explicitly activated. In an AWS Organizations setup, cost allocation tags must be activated from the management account.

Step-by-Step Solution

1
Sign in to the AWS Management Console using the credentials of the management (payer) account of the organization.
Access to consolidated billing and organization-wide cost management features is established.
Only the management account has the permissions required to manage cost allocation tags for member accounts in an organization.
2
Navigate to the AWS Billing and Cost Management console, select 'Cost allocation tags' from the navigation pane, locate the user-defined tag key `ProjectName`, select it, and click 'Activate'.
The `ProjectName` tag is registered for cost allocation tracking.
Applying a tag to resources does not automatically designate it for billing. It must be explicitly activated to begin appearing in AWS Cost Explorer and cost reports.
