AWS Certified Cloud Practitioner — Question 384

A company needs the historical cost and service usage details of its Amazon EC2 instances.

Which AWS service or tool will provide this information?

Answer options

• A. AWS Budgets
• B. Amazon Forecast
• C. AWS Cost Explorer
• D. AWS Pricing Calculator

Correct answer: C

Explanation

AWS Cost Explorer is the correct tool because it allows users to visualize, understand, and analyze their historical AWS cost and usage data over time. AWS Budgets is used to set custom budgets and receive alerts, AWS Pricing Calculator estimates costs for planned services, and Amazon Forecast is a machine learning service for time-series forecasting, making them incorrect for retrieving historical EC2 usage details.
