What information does AWS Trusted Advisor provide?

AWS Trusted Advisor is a tool designed to help users optimize their AWS infrastructure by providing real-time guidance on best practices. It offers insights into various aspects of AWS accounts, primarily focusing on cost optimization, performance improvements, security enhancements, and service limits.

The correct answer highlights that AWS Trusted Advisor assesses the usage of fault tolerance within a user’s AWS environment. Fault tolerance refers to the ability of a system to continue operating properly in the event of a failure of some of its components. Trusted Advisor evaluates the extent to which your AWS resources are designed to tolerate failures, suggesting enhancements like deploying resources across multiple Availability Zones or using load balancers to improve application resiliency.

The other options provided don't accurately reflect the primary functionalities of AWS Trusted Advisor. For example, while it does help identify cost-saving opportunities, the direct mention of service limits and cost savings is part of a broader set of recommendations rather than being the primary focus. The tool does not actively report on security breaches, which fall under different security monitoring solutions, nor does it generate regular monthly usage reports for all services, which are typically
