Which of the following is a characteristic of AD DS replication?

• A. Group replication
• B. Broadcast reduction
• C. Pull replication
• D. Data store partitioning

Answer: (C)

AD DS replication uses a pull-based model. A domain controller fetches updates from its replication partners on a scheduled basis, pulling only the changes it needs since its last synchronization. This approach, driven by Change Sequence Numbers (USNs), keeps all DCs in sync while minimizing network traffic and allowing offline controllers to catch up when they come back online. It also fits the multi-master, partitioned nature of AD data, where changes in a naming context on one DC are propagated to others through pull replication. The idea that replication happens as a broadcast or push to groups isn’t how AD DS handles updates, and “data store partitioning” describes how data is organized into partitions rather than how replication moves data between controllers.
