AWS Certified Cloud Practitioner — Question 891

Which task requires using AWS account root user credentials?

Answer options

• A. Viewing billing information
• B. Changing the AWS Support plan
• C. Starting and stopping Amazon EC2 instances
• D. Opening an AWS Support case

Correct answer: B

Explanation

Modifying the AWS Support plan is a highly privileged task that specifically requires AWS account root user credentials. Other day-to-day administrative activities, such as managing Amazon EC2 instances, viewing billing details, or opening support cases, can be safely delegated to IAM users by assigning the appropriate IAM policies.
