Explanation

C - OK - new in 12c Example 25-1 illustrates how to perform active duplication. RMAN uses the pull method DUPLICATE TARGET DATABASE TO dupdb FROM ACTIVE DATABASE NOFILENAMECHECK; D,E - OK - new in 12c As of Oracle Database 12c, RMAN lets you restore or recover files by connecting, over the network, to a physical standby database that contains the required files. You can restore an entire database, data files, control files, spfile, or tablespaces. Restoring files over the network is very useful in scenarios where you need to synchronize the primary and standby databases. https://docs.oracle.com/database/121/SBYDB/rman.htm#SBYDB5457 RMAN restores database files, over the network, from a physical standby database by using the FROM SERVICE clause of the RESTORE command. The FROM SERVICE clause provides the service name of the physical standby database from which the files must be restored. During the restore operation, RMAN creates backup sets, on the physical standby database, of the files that need to be restored and then transfers these backup sets to the target database over the
