AWS Certified SysOps Administrator Practice Exam

Which AWS service can help identify storage optimization opportunities for an S3 environment?

1. AWS Trusted Advisor

2. AWS Directory Service

3. AWS Identity and Access Management

4. AWS CloudFront

The correct answer is: AWS Trusted Advisor

The most fitting option for identifying storage optimization opportunities in an S3 environment is AWS Trusted Advisor. Trusted Advisor is a management tool that provides real-time guidance to help you provision your resources following AWS best practices. One of its features includes the ability to analyze your S3 usage and identify areas where you can reduce costs by optimizing storage, such as recommendations for underutilized or idle storage. The other options serve different purposes. AWS Directory Service is focused on managing directories and integrating with Microsoft Active Directory, making it unrelated to storage optimization. AWS Identity and Access Management (IAM) is centered around access control and managing permissions for AWS services, which does not pertain to storage optimization either. AWS CloudFront is a content delivery network (CDN) service that accelerates the delivery of content but does not provide insights into optimizing storage within S3. Therefore, AWS Trusted Advisor is specifically designed to help users manage their AWS resources more effectively, including identifying optimization opportunities in S3.
