A is correct answer , multiple account, With tag you cannot control all type of data transfer , Tag is also only for the services and it said exact!

what about the services that are rarely used?

yo opino que es la a por que la b solo dice de etiquetar los recursos que mas se usan

Option B talks about the tags for services which can give bill services wise not department wise. While for option A. billing will generate according to different department

the key word here is exact

The answer is A. Read this article and you'll see the answer is stated there. https://docs.aws.amazon.com/whitepapers/latest/organizing-your-aws-environment/benefits-of-using-multiple-aws-accounts.html#manage-costs

A. Use one AWS account for each department.

They are only tagging most used services with allocation tags where as company wants complete bifurcation of their departmental bills which makes A the correct answer.

B. Use cost allocation tags on services that are used the most often. Cost Allocation Tags: AWS allows you to apply tags to resources such as EC2 instances, S3 buckets, and other services. Tags are key-value pairs that can be used to categorize and organize resources. By applying cost allocation tags to resources used by each department, the company can track usage and costs at a granular level. Using one AWS account for each department can be a valid approach, but it can lead to management overhead and complexity if there are many departments. Cost allocation tags can be a more flexible and scalable solution.

Option B states allocated tags are assigned only to services that are used the MOST OFTEN. not all services. So I'd go for A

*exact* AWS Cloud usage

B. Use cost allocation tags on services that are used the most often. Cost allocation tags allow you to assign metadata to your AWS resources, such as EC2 instances, S3 buckets, or RDS databases. By using cost allocation tags, you can categorize your resources by department, project, or any other relevant criteria. This enables you to track and allocate costs accurately based on these tags.

One AWS account for each department, grouped into an organization, will achieve full cost coverage.

To determine AWS Cloud usage costs by department, the company can use cost allocation tags (B) on services that are used most often. Cost allocation tags are labels that can be applied to AWS resources such as EC2 instances, S3 buckets, and RDS instances, to categorize and track costs. By tagging resources with department-specific tags, the company can use AWS Cost Explorer to view detailed billing reports for each department.
