You are part of the IT team of a small car manufacturer company. The company is starting to move its On-Premise resources to the cloud. The Marketing department was the first department to migrate its applications to the cloud. Now the finance team wants to do the same. Each department should have its own AWS account but you need one management account to pay for the bills of all the AWS accounts. What do you suggest to solve this?

Answer options:

A.Create a different VPC for the Finance Department and limit their access to resources with IAM Roles and Policies.
B.Use AWS Control Tower.
C.Use AWS Organizations to manage both AWS accounts.
D.Use AWS Cost Explorer to divide the bills and use IAM policies to limit the access to resources.

Correct Answer: C
Option A is incorrect. This option does not cover the splitting bill requirements. Also, a different VPC is not the best option to separate projects or environments.
Option B is incorrect. Control Tower is more suitable to automate a deployment in multi-account environments. More details: https://aws.amazon.com/controltower/faqs/
Option C is CORRECT. With AWS Organizations, you can have separate bills for every account and pay it with the same account using consolidating billing. More details: https://aws.amazon.com/organizations/faqs/.
Option D is incorrect. With AWS Cost Explorer, you can analyze and explore your bills and service usage in the account. But in the end, there will be one bill for the account. More details- https://aws.amazon.com/aws-cost-management/faqs/
