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

A.
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.

B.
Use the d3MS_pdb package to plug the Oracle 11g database into the existing CDB as a
PDB.

C.
Use the create database … enable pluggable database statement to create a PDB by
copying data files from pd3Sseed and use data pump to load data from the Oracle 11g
database into the newly created PDB.

D.
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.

E.
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.
