A solutions architect has created a new AWS account and must secure AWS account root user access. Which combination of actions will accomplish this? (Choose two.)

Securing the AWS account root user is paramount. A strong password makes it significantly harder for unauthorized individuals to guess or crack the credentials. Enabling multi-factor authentication (MFA) adds an essential layer of security, requiring a second verification factor in addition to the password, even if the password is compromised. Storing root user access keys in an S3 bucket is not recommended; root user access keys should generally not be used for programmatic access and should be deleted if they exist. The root user already has full administrative permissions by default, so adding it to a group or applying an inline policy is redundant and unnecessary.
