AWS DevOps Engineer Professional Practice Test 2025 - Free DevOps Practice Questions and Certification Study Guide

The correct answer is AWS Trusted Advisor, which is designed to provide best practices and recommendations that can help users optimize their AWS environment. It evaluates an organization's AWS account and gives insights on various aspects such as cost optimization, performance, security, and fault tolerance. By doing so, it helps identify potential risks and areas where improvements can be made to enhance the overall security and efficiency of the cloud system.

Trusted Advisor's security checks can highlight issues such as unencrypted data, open security groups, and IAM access keys that have not been rotated, allowing organizations to take proactive measures to mitigate those risks. Its actionable recommendations empower users to strengthen their cloud security posture.

In contrast, while services like AWS Shield, AWS Inspector, and AWS CloudTrail contribute to security and compliance, they focus on specific functions. Shield provides protection against DDoS attacks, Inspector assesses application vulnerabilities, and CloudTrail enables logging and monitoring of account activity. These services are valuable in their roles but do not offer the overarching risk management approach that Trusted Advisor provides across various dimensions of an AWS account.
