As an AWS system administrator working in a startup, you need to publish the AWS billing information to an Amazon Simple Storage Service (Amazon S3) bucket. The billing data should include the cost and usage of each product in CSV format and should be refreshed daily. How would you implement this in the easiest way?

Answer options:

A.In the AWS Billing and Cost Management console, create the Cost and Usage Reports and deliver the reports to an S3 bucket.
B.In the AWS Cost Explorer console, register an S3 bucket to receive the daily cost and usage information.
C.In the AWS Saving Plans console, register a savings plan to publish the daily cost and usage data to a custom S3 bucket.
D.In AWS Budgets, create a cost and usage budget plan that automatically transfers the billing data to an S3 bucket.

Correct Answer: A
Option A is CORRECT because Cost and Usage Reports provide the required data to an S3 bucket. Users can choose the report granularity to be hourly, daily or monthly.
Option B is incorrect because, in AWS Cost Explorer, users cannot register an S3 bucket to receive the billing data.
Option C is incorrect because a savings plan cannot provide daily cost and usage data.
Option D is incorrect because there is no cost and usage budget plan in AWS Budgets. The description is invalid.
