Which changes should be made in ADUC when setting up a new user account?

When setting up a new user account in Active Directory User Accounts (ADUC), it is essential to ensure that the correct email domain is associated with the user's account. The answer provided indicates using "DOD + 117004, @mil," which reflects the appropriate username format for Department of Defense (DOD) personnel. This format is crucial because it aligns with the military's standardized naming conventions, ensuring that the user account is properly recognized within the system and can access the necessary resources.

Using the correct domain (@mil) is an important part of user account management in a military or government context, as it helps maintain security, organization, and access rights within the network.

While other options may touch on aspects of user account setup, they do not specifically address the fundamental requirement of using the correct username format tied to the organization's domain, which is critical for operational integrity and compliance.
