A user can use the same login credentials on any computer in an Active Directory Domain.

A user can use the same login credentials on any computer in an Active Directory Domain.

• A. True
• B. False
• C. Only on networked computers
• D. Only with roaming profiles

Answer: (A)

In an Active Directory domain, authentication is centralized. User accounts and passwords are stored in AD, and every domain-joined computer trusts that domain for logons. When a user signs in on any domain computer, the system validates the credentials with a domain controller (typically using Kerberos). As long as the computer can reach a DC, that user’s identity is recognized across the entire domain, and the same credentials grant access on any machine joined to that domain. The fact that roaming profiles exist is unrelated to this behavior; roaming profiles move user data, not the ability to log on with the same credentials. (If a DC isn’t reachable, Windows can sometimes use cached credentials, but the intended model is centralized authentication across domain-joined machines.)
