Correct Answer: C. Tag all the AWS resources with a key for cost and a value of the application's name. Activate cost allocation tags. Use Cost Explorer to get the desired information.

Explanation

The most cost-effective solution to meet the company's requirements is:C. Tag all the AWS resources with a key for cost and a value of the application's name. Activate cost allocation tags. Use Cost Explorer to get the desired information.Here's why:Cost Allocation Tags: Cost allocation tags allow you to categorize your AWS resources based on application names or other relevant criteria. This enables you to break down costs by application.Cost Explorer: Cost Explorer is a free, built-in tool that provides detailed cost analysis and reporting capabilities. It allows you to filter and group costs based on tags, providing the desired breakdown of costs for each application.Regular Reports: Cost Explorer offers customizable reports that can be scheduled to be delivered regularly, meeting the company's requirement for a recurring report.Why other options are less efficient or cost-effective:A. Use AWS Budgets to download data for the past 3 months into a .csv file. Look up the desired information. While AWS Budgets can provide cost data, it's not designed for detailed application-level cost analysis. It's primarily for setting spending limits.B. Load AWS Cost and Usage Reports into an Amazon RDS DB instance. Run SQL queries to get the desired information. This approach involves additional infrastructure costs for the RDS instance and data loading, making it less cost-effective.D. Tag all the AWS resources with a key for cost and a value of the application's name. Use the AWS Billing and Cost Management console to download bills for the past 3 months.Look up the desired information. This approach requires manual analysis of downloaded bills, which is inefficient and prone to errors.In summary:Option C provides the most cost-effective and efficient solution by leveraging cost allocation tags and Cost Explorer. It allows for accurate cost breakdown by application, customizable reports, and regular delivery, meeting the company's requirements without additional infrastructure costs.
