• Question 376:

  A company is running workloads for multiple departments within a single VPC. The company needs to be able to bill each department for its resource usage. Which action should the company take to accomplish this goal with the LEAST operational overhead?

  A. Add a department tag to each resource and configure cost allocation tags.
  B. Move each department resource to its own VPC.
  C. Move each department resource to its own AWS account.
  D. Use AWS Organizations to get a billing report for each department.
  A. Add a department tag to each resource and configure cost allocation tags.

  ---

  Explanation/Reference:

  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.
