Which three statements are true about the startup and shutdown of multitenant container
databases (CDBs) and pluggable databases (PDBs)?
A.
When a CDB is open in restricted mode, PDBs must also be opened in restricted mode.
B.
When a CDB is in mount state, PDBs are automatically placed in mount state.
C.
All PDBs must be shut down before shutting down a CDB instance.
D.
When a CDB instance is started, PDBs can be placed in open state by using database
triggers or by executing the alter pluggable database command.
E.
A PDB opened in restricted mode allows only local users to connect.
I would Say A, B and D
Answer C is incorrect. I can shutdown a CDB with PDB in open state (in my lab, with Oracle 12.1)
A, B, D.
A- When a CDB is open in restricted mode, PDBs are placed in mount state.
C- “Must be” is misleading
E- local user with restricted session privilege can connect to pdb. statement incomplete
I can say only B,D are correct
