Question #879

Which practices are recommended for securing an AWS account root user? (Choose two.)

A

Store root user access keys for backup purposes.

B

Use the root user account for regular administrative activities.

C

Activate multi-factor authentication (MFA) for the root user.

D

Set up an IAM user with administrator permissions for daily tasks.

E

Provision additional root users for separate business units.

Explanation

C and D are correct because:
- C: Activating MFA for the root user adds an extra layer of protection against unauthorized access, a core AWS security recommendation.
- D: Using an IAM user with admin permissions for daily tasks reduces reliance on the root user, limiting its exposure to potential risks.

Other options are incorrect:
- A: Root access keys should never be created or stored, as they bypass all IAM policies and pose a severe security risk.
- B: The root user should only perform account-level tasks (e.g., changing billing info), not regular administrative work.
- E: AWS accounts have only one root user; additional root users cannot be provisioned.

Key Points: Always enable MFA for the root user, avoid using it for daily tasks, and use IAM roles/users instead.

Answer

The correct answer is: CD
