AWS Certified SysOps Administrator – Associate (legacy) — Question 345

A user is trying to understand the CloudWatch metrics for the AWS services. It is required that the user should first understand the namespace for the AWS services. Which of the below mentioned is not a valid namespace for the AWS services?

Answer options

• A. AWS/StorageGateway
• B. AWS/CloudTrail
• C. AWS/ElastiCache
• D. AWS/SWF

Correct answer: B

Explanation

AWS services that publish metrics to Amazon CloudWatch use a specific namespace convention prefixed with 'AWS/'. While AWS/StorageGateway, AWS/ElastiCache, and AWS/SWF are valid service namespaces, AWS/CloudTrail is not a valid metric namespace because CloudTrail integration with CloudWatch is handled via CloudWatch Logs rather than direct metric namespaces.
