Which technique should you use to minimize down time while plugging this non-CDB into the CDB?

You are about to plug a multi-terabyte non-CDB into an existing multitenant container database
(CDB) as a pluggable database (PDB).
The characteristics of the non-CDB are as follows:
Version: Oracle Database 12c Releases 1 64-bit
Character set: WE8ISO8859P15
National character set: AL16UTF16
O/S: Oracle Linux 6 64-bit
The characteristics of the CDB are as follows:
Version: Oracle Database 12c Release 1 64-bit
Character set: AL32UTF8
O/S: Oracle Linux 6 64-bit
Which technique should you use to minimize down time while plugging this non-CDB into the
CDB?

A.
Transportable database

B.
Transportable tablespace

C.
Data Pump full export / import

D.
The DBMS_PDB package

E.
RMAN

Explanation:

Note:
* Generating a Pluggable Database Manifest File for the Non-CDB
Execute the dbms_pdb.describe procedure to generate the manifest file.
exec dbms_pdb.describe(pdb_descr_file=>’/u01/app/oracle/oradata/noncdb/noncdb.xml’);
Shut down the noncdb instance to prepare to copy the data files in the next section.
shutdown immediate
exit
