You plan to duplicate multitenant container database (CDB) cdb1 that contains the pluggable database (PDB) SALES:
RMAN> DUPLICATE TARGET DATBASE TO cdbdup
PLUGGABLE DATABASE sales
FROM ACTIVE DATABASE
PASSWORD FILE
SPFILE
NOFILENAMECHECK;
Which two statements are true?
A.
The root and seed databases are included in the duplication.
B.
Only the SALES PDB is duplicated as the non-CDB CDBDUP.
C.
A backup of the SALES PDB must exist before the execution of the command.
D.
An auxiliary instance must have been started with the initialization parameter
ENABLE_PLUGGABLE_DATABASE set to TRUE.
E.
RMAN must be connected to a recovery catalog for the execution of the command.
AD
To duplicate PDBs, you must create the auxiliary instance as a CDB. To do so, start the instance with the declaration enable_pluggable_database=TRUE in the initialization parameter file. When you duplicate one or more PDBs, RMAN also duplicates the root (CDB$ROOT) and the seed database (PDB$SEED). The resulting duplicate database is a fully functional CDB that contains the root, the seed database

Might be C too
