question 347

Multiple Choice

A company's legacy application uses IAM user credentials to access resources in the company's AWS Organizations organization. A DevOps engineer needs to ensure new IAM users cannot be created unless the employee creating the IAM user is on an exception list. Which solution will meet these requirements?

• A) Attach an Organizations SCP with an explicit deny for all iam:CreateAccessKey actions with a condition that excludes StringNotEquals for aws:username with a value of the exception list.
• B) Attach an Organizations SCP with an explicit deny for all iam:CreateUser actions with a condition that includes StringNotLike for aws:username with a value of the exception list.
• C) Create an Amazon EventBridge (Amazon CloudWatch Events) rule with a pattern that matches the iam:CreateAccessKey action with an AWS Lambda function target. The function will check the user name account against an exception list. If the user is not in the exception list, the function will delete the user.
• D) Create an Amazon EventBridge (Amazon CloudWatch Events) rule with a pattern that matches the iam:CreateUser action with an AWS Lambda function target. The function will check the user name and account against an exception list. If the user is not in the exception list, the function will delete the user.
