Which task requires a user to sign in as the AWS account root user?
The deletion of IAM users
The deletion of an AWS account
The creation of an organization in AWS Organizations
The deletion of Amazon EC2 instances
Explanations:
Deleting IAM users can be performed by users with the necessary IAM permissions. It does not require root user access.
Deleting an AWS account can only be done by the root user. This is a critical operation that affects the entire account and requires the highest level of access.
Creating an organization in AWS Organizations can be done by users with appropriate IAM permissions; it does not necessitate root user access.
Deleting Amazon EC2 instances can also be done by users with sufficient IAM permissions. It does not require signing in as the root user.
I plan that the answer is:
The deletion of an AWS account
