Answer: AWS Trusted Advisor

The correct answer is D, AWS Trusted Advisor. AWS Trusted Advisor is a service that provides recommendations to help you follow AWS best practices. One of its checks is 'Security Groups - Specific Ports Unrestricted', which identifies security groups that allow unrestricted access to specific ports, including SSH. This helps in identifying potential security risks where access is not properly restricted. The other options are not relevant to this specific task: Amazon Cognito is an identity service, AWS Shield is for DDoS protection, and Amazon Macie is for discovering and protecting sensitive data.
