Oracle Database Administration II — Question 161

Which three are true about cloning databases into an existing CDB with RMAN? (Choose three.)

Answer options

• A. A user with SYSDBA or SYSBKUP must be logged in with RMAN to the non-CDB being cloned when cloning a non-CDB.
• B. The target and auxiliary instance passwords must be the same.
• C. Two or more PDBs can be cloned with the same command.
• D. A non-CDB can be cloned into a PDB.
• E. Only one PDB can be cloned at a time.
• F. A user with SYSDBA or SYSBKUP must be logged in with RMAN to CDB$ROOT when cloning a PDB.

Correct answer: B, E, F

Explanation

The correct answers are B, E, and F because for cloning to succeed, the passwords for both the target and auxiliary instances must indeed match (B), only one PDB can be cloned at a time (E), and a user with the appropriate privileges must be logged into CDB$ROOT (F). Options A, C, and D are incorrect; a user must be logged into the CDB for PDB cloning, multiple PDBs cannot be cloned simultaneously, and cloning a non-CDB into a PDB is not supported.
