Which method should an administrator of the BIG-IP use to sync the configuration to only certain other BIG-IPs?

Folder synchronization controls what configuration objects are synced, not which devices receive the sync.

Traffic Groups manage floating IP resources and failover behavior, not configuration synchronization targets.

Sync Groups in BIG-IP define which devices are included in a configuration synchronization relationship. By excluding certain devices from a Sync Group, an administrator can ensure that a configuration push only reaches the intended subset of BIG-IP devices, rather than propagating to all trusted peers.

Device Groups define trust and failover relationships but are not the mechanism used to selectively target devices for a configuration sync operation.
