Which combination of actions will accomplish this?
(Choose two.)
Ensure the root user uses a strong password.
Enable multi-factor authentication to the root user.
Store root user access keys in an encrypted Amazon S3 bucket.
Add the root user to a group containing administrative permissions.
Apply the required permissions to the root user with an inline policy document.
Explanations:
Ensuring the root user uses a strong password is fundamental for account security.
Enabling multi-factor authentication (MFA) adds an essential layer of security for the root user.
Storing root user access keys in an S3 bucket is not recommended; root access keys should not be used.
Adding the root user to a group is not applicable since root users cannot be added to groups.
Applying inline policies to the root user is unnecessary and not recommended; the root user has full permissions by default.
As I see it, the answer is:
Ensure the root user uses a strong password.
