Which component enables data synchronization to passive members?

• A. bloxSync, via the active member
• B. GridSync
• C. SyncAgent
• D. DataReplicator

Answer: (A)

The mechanism that makes sure passive members stay up to date is bloxSync, which runs on the active member and pushes incremental updates to each passive member. The active member holds the authoritative data, and bloxSync propagates changes such as DNS zones and grid configuration out to the passives, keeping them synchronized without each passive pulling updates itself. GridSync operates at the grid level as the overall synchronization framework, but the actual delivery to passive members is accomplished by bloxSync via the active member. The other components aren’t used for this specific passive synchronization path.
