Which three statements are true about redo transport?

With synchronous redo transport, LGWR ships redo directly to RFS processes on the standby database instances and waits for an acknowledgment.

An RFS process on a standby database instance may receive redo from an archiver process on the primary database instance to perform archive gap resolution.

With asynchronous redo transport, TTnn processes may read redo from the log buffer or from standby redo logs on the primary database.

Multiple RFS processes may receive redo on one standby database instance.

Multiple RFS processes may receive redo on one far sync instance.
