AWS Certified Solutions Architect – Associate (SAA-C02) — Question 393

A company hosts multiple production applications. One of the applications consists of resources from Amazon EC2, AWS Lambda, Amazon RDS, Amazon Simple
Notification Service (Amazon SNS), and Amazon Simple Queue Service (Amazon SQS) across multiple AWS Regions. All company resources are tagged with a tag name of `application` and a value that corresponds to each application. A solutions architect must provide the quickest solution for identifying all of the tagged components.
Which solution meets these requirements?

Answer options

• A. Use AWS CloudTrail to generate a list of resources with the application tag.
• B. Use the AWS CLI to query each service across all Regions to report the tagged components.
• C. Run a query in Amazon CloudWatch Logs Insights to report on the components with the application tag.
• D. Run a query with the AWS Resource Groups Tag Editor to report on the resources globally with the application tag.

Correct answer: D

Explanation

The AWS Resource Groups Tag Editor is the most efficient service for searching and identifying resources globally across multiple AWS Regions based on tags. AWS CloudTrail and Amazon CloudWatch Logs Insights (options A and C) are logging and log analysis tools, not resource discovery tools. While using the AWS CLI (option B) is technically possible, it requires writing and maintaining complex scripts across multiple services and regions, making it far slower than using Tag Editor.
