A company wants to review its monthly costs of using Amazon EC2 and Amazon RDS for the past year.
Which AWS service or tool provides this information?
AWS Trusted Advisor
Cost Explorer
Amazon Forecast
Amazon CloudWatch
Explanations:
AWS Trusted Advisor provides best practices and recommendations but does not focus on cost analysis.
Cost Explorer is specifically designed to help users analyze their AWS spending and usage, making it the correct choice for reviewing monthly costs.
Amazon Forecast is used for predicting future business outcomes based on historical data, not for reviewing costs.
Amazon CloudWatch monitors resources and applications but does not provide detailed cost analysis.
I organize that the answer is:
Cost Explorer
