Correct Answer: A,C,D
Explanation/Reference:
Explanation:
Starting with Oracle Database 12c Release 1 (12.1), RMAN can use backup sets to transfer the source database files that need to be duplicated. The backup sets are transferred over the network to the auxiliary database. Backup sets can be encrypted for additional security. Specify the encryption algorithm by using the SET ENCRYPTION ALGORITHM command before the DUPLICATE command. RMAN uses backup sets to perform active database duplication when the connection to the target database is established using a net service name and any one of the following conditions is satisfied: The DUPLICATE ... FROM ACTIVE DATABASE command contains either the USING BACKUPSET, USING COMPRESSED BACKUPSET, or SECTION SIZE clause. The number of auxiliary channels allocated is equal to or greater than the number of target channels allocated. http://docs.oracle.com/database/121/BRADV/ rcmdupdb.htm#BRADV298
