Exam AWS Certified Cloud Practitioner topic 1 question 824 discussion

Option A (adding a department tag to each resource and configuring cost allocation tags) is the option with the least operational overhead because it does not require moving resources to separate VPCs or AWS accounts, which can be time-consuming and complex to set up and manage. Instead, it simply involves adding a tag to each resource and configuring cost allocation tags, which is a relatively straightforward process. Once set up, the cost allocation tags will automatically generate detailed billing reports that are broken down by department, enabling each department to be charged only for the resources that it uses.

Answer A: cost allocation tags "A tag is a label that you or AWS assigns to an AWS resource. Each tag consists of a key and a value. For each resource, each tag key must be unique, and each tag key can have only one value. You can use tags to organize your resources, and cost allocation tags to track your AWS costs on a detailed level. After you activate cost allocation tags, AWS uses the cost allocation tags to organize your resource costs on your cost allocation report, to make it easier for you to categorize and track your AWS costs.
