Which service generates a detailed billing report containing line items for each AWS product and usage type?

• A. AWS Cost Explorer
• B. Savings Plans
• C. Amazon EC2
• D. AWS Cost and Usage Report

Answer: (D)

The ability to produce a detailed bill with a line-item for every AWS product and usage type is provided by the Cost and Usage Report. This report is designed to give full, granular visibility into what you’re being charged for, broken down by product, usage type, region, and resource, and it can include resource IDs if you enable that option. The report is delivered to an S3 bucket in CSV or Parquet format, making it ideal for feeding into custom analyses, dashboards, or data pipelines.

This is different from Cost Explorer, which offers interactive dashboards and summarized views of costs and usage rather than raw, per-line-item data. Savings Plans is a pricing model that can affect how you’re charged, but it’s not a reporting tool. Amazon EC2 is a compute service and does not itself generate billing reports.
