Which statement is true about the synchronization process, as performed by the Configuration Utility or by typing b config sync all.

Config sync should be run from the active system or the system holding the desired configuration, not necessarily the standby, to push the correct config to the peer.

While running sync from the system with the latest configuration is generally best practice, the answer is incomplete - the key technical fact being tested is which file is synchronized, not which system initiates it.

During a config sync operation - whether run via the Configuration Utility or 'b config sync all' - the /config/BIG-IP.conf file is copied from the source system to the peer, making the two files identical. This is the primary configuration file synced in a standard BIG-IP high-availability sync operation.

/config/BIG-IP_base.conf contains base network configuration that is not synchronized during a standard config sync; only /config/BIG-IP.conf is synchronized.
