Oracle Database Administration II — Question 172

Which are two of the steps taken by Database Configuration Assistant (DBCA) to clone a remote pluggable database (PDB) starting from Oracle 19c? (Choose two.)

Answer options

• A. backing up the cloned PDB
• B. opening the cloned PDB
• C. creating a database link from CDB$ROOT in the local database to CDB$ROOT in the remote system that is to be cloned
• D. creating a database link from CDB$ROOT in the local database to the PDB in the remote system that is to be cloned
• E. leaving the cloned PDB in mount state

Correct answer: B, C

Explanation

The correct answers are B and C because DBCA opens the cloned PDB and establishes a database link to the remote CDB$ROOT, which is essential for the cloning process. Options A and E are incorrect as DBCA does not back up or leave the cloned PDB in mount state during this operation, and option D is also incorrect as the link is created to the CDB$ROOT, not directly to the PDB.
