Which two methods can be used to add an Oracle 11g database to a multitenant container database (CDB) as a pluggable database (PDB)? (Choose two.)

A. Use the DBMS_PDB package to plug the Oracle 11g database into the existing CDB as a PDB.
B. Use the CREATE DATABASE ... ENABLE PLUGGABLE DATABASE statement to create a PDB by copying data files from PDB$SEED and use data pump to load data from the Oracle 11g database into the newly created PDB.
C. Pre-create a PDB in CDB and use data pump to load data from the complete database export of the Oracle 11g database into the newly created PDB.
D. Pre-create a PDB in CDB and use the NETWORK_LINK and PARALLEL parameters with data pump import to import data from the Oracle 11g database to the newly created PDB. E. Upgrade the Oracle 11g database to a 12c non-CDB and use the DBMS_PDB.DESCRIBE procedure to plug the database as a new PDB into the CDB.
