To store AWS Cost and Usage Report files, which AWS service must be used?

1. An S3 Bucket that you own

2. Trusted Advisor

3. An AWS owned S3 Bucket

4. CloudWatch

The correct answer is: An S3 Bucket that you own

The AWS Cost and Usage Report files are designed to be stored in an Amazon S3 bucket that you own. This service provides the flexibility and scalability needed to manage large amounts of data, such as detailed billing information from AWS usage. When you set up the AWS Cost and Usage Reports, you must specify an existing S3 bucket where the report files will be delivered. This option ensures you have complete control over the bucket, its configurations, and access permissions. Additionally, utilizing your own S3 bucket allows for easy integration with other AWS services for further data processing and analysis. Other options do not serve the purpose of storing these reports. Trusted Advisor is a tool that provides recommendations regarding best practices for your AWS environment, but it does not provide storage capabilities. An AWS-owned S3 bucket does not exist for customers to access or store their reports, as AWS manages account-level resources distinctly. CloudWatch, while instrumental in monitoring and logging AWS resources, does not provide file storage capabilities for cost reports. Thus, only an S3 bucket that you own is the appropriate destination for AWS Cost and Usage Report files.
