Which statement is correct regarding domain controller replication?

• A. Changes on one Domain Controller will replicate to synchronize changes to other DCs.
• B. Replication is not automatic
• C. You must manually trigger replication
• D. Replication only occurs within a single domain

Answer: (A)

Domain Controller replication automatically keeps all DCs in sync. In Active Directory, any change made on one Domain Controller is recorded and then propagated to other DCs through the replication topology. This is multi-master replication, so every DC can accept updates and these updates are replicated to others to maintain a consistent directory across the domain and, when applicable, across the forest. The process is asynchronous and governed by sites, link costs, and schedules, which can affect how quickly changes appear on other DCs. You generally don’t have to manually trigger replication; it runs by design, though you can initiate replication if you need to expedite it. Because replication spans domains and is designed to keep data consistent across the forest, the statement that it only happens within a single domain isn’t accurate.
