Answer: Amazon CloudWatch

## Explanation Amazon CloudWatch is the correct AWS service that shows whether an Amazon EC2 instance has failed status checks. ### Why Amazon CloudWatch? - **EC2 Status Checks**: CloudWatch monitors EC2 instances and provides status checks that include: - **System Status Checks**: Monitor the AWS systems required to use your instance - **Instance Status Checks**: Monitor the software and network configuration of your individual instance - **Monitoring Capabilities**: CloudWatch collects monitoring and operational data in the form of logs, metrics, and events - **Alarms and Notifications**: You can set up CloudWatch alarms to notify you when status checks fail ### Why not the other options? - **AWS CloudTrail**: Records API calls and management events for auditing and compliance, not for monitoring instance health - **AWS Health Dashboard**: Provides information about AWS service health and personal health events, but not specific EC2 instance status checks - **AWS Cloud Map**: A service discovery service for cloud resources, not for monitoring instance health CloudWatch is specifically designed for monitoring AWS resources and provides detailed metrics and status information for EC2 instances.
