Which of the following is a characteristic of the AWS account root user?
The root user is the only user that can be configured with multi-factor authentication (MFA).
The root user is the only user that can access the AWS Management Console.
The root user is the first sign-in identity that is available when an AWS account is created.
The root user has a password that cannot be changed.
Explanations:
The root user is not the only user that can be configured with MFA; other IAM users can also be configured with MFA.
The root user is not the only user that can access the AWS Management Console; IAM users can also access it with appropriate permissions.
The root user is indeed the first sign-in identity created when an AWS account is set up.
The root user’s password can be changed, just like any other user in AWS.
I gauge that the answer is:
The root user is the first sign-in identity that is available when an AWS account is created.
