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 can be configured with MFA, but it is not the only user that can be configured with MFA.
Other IAM users can access the AWS Management Console, not just the root user.
The root user is the first sign-in identity available when an AWS account is created.
The root user password can be changed just like any other user in AWS.
I plot that the answer is:
The root user is the first sign-in identity that is available when an AWS account is created.
