Which tool allows you to monitor AWS service usage and costs?

• A. AWS CloudTrail
• B. AWS Cost Explorer
• C. AWS Trusted Advisor
• D. AWS Personal Health Dashboard

Answer: (B)

AWS Cost Explorer is the primary tool designed to help users monitor their AWS service usage and associated costs effectively. It provides a user-friendly interface that enables you to visualize your spending patterns and usage of AWS services over time. With AWS Cost Explorer, you can break down costs by different dimensions such as service, account, and region, which helps in identifying trends and spikes in spending. Additionally, AWS Cost Explorer allows for forecasting costs based on historical data, making it highly beneficial for budgeting and financial planning for cloud resources. It provides insights that can help users optimize their AWS usage, manage budgets, and ultimately reduce costs. In contrast, the other tools mentioned serve different purposes. AWS CloudTrail is focused on logging and monitoring account activity and API usage across AWS, which is more about governance and security rather than financial aspects. AWS Trusted Advisor offers real-time guidance to help you provision your resources following AWS best practices, addressing areas such as cost optimization, but it does not specifically focus on monitoring costs or usage over time. Finally, the AWS Personal Health Dashboard provides alerts and guidance when AWS is experiencing events that may impact your resources, which is crucial for operational health but not directly tied to monitoring costs or usage.
