Oracle Database Administration II — Question 130

Which three resources are always shared among CDB$ROOT and pluggable databases (PDBs)? (Choose three.)

Answer options

• A. the data dictionary in CDB$ROOT
• B. temporary tablespaces
• C. the Process Monitor Process (PMON)
• D. SYSAUX tablespaces
• E. the log writer process (LGWR)
• F. undo tablespaces

Correct answer: A, C, E

Explanation

The correct answer includes the data dictionary in CDB$ROOT, the Process Monitor Process (PMON), and the log writer process (LGWR) as these are shared resources between the container and pluggable databases. Temporary tablespaces, SYSAUX tablespaces, and undo tablespaces are not shared; they can be defined separately for each PDB.
