A Microsoft domain can have multiple domain controllers.

• A. FALSE
• B. TRUE
• C. Depends on domain functional level
• D. Not applicable

Answer: (B)

In Active Directory, a domain can be supported by more than one domain controller. This setup provides redundancy and better performance: each domain controller holds a copy of the domain’s data and they replicate changes among themselves, so if one controller goes down, others can still authenticate users and apply policies. The domain functional level controls available AD features, not how many domain controllers you can have, so you can deploy multiple domain controllers at any supported functional level. This makes the statement true and aligns with standard best practices for availability and resilience.
