Your multitenant container database (CDB) contains a pluggable database, HR_PDB. The
default permanent tablespace in HR_PDB is USERDATA. The container database (CDB) is

BACKUP TABLESPACE hr_pdb:userdata; Which task should you perform before issuing
the command?
A.
Place the root container in ARHCHIVELOG mode.
B.
Take the user data tablespace offline.
C.
Place the root container in the nomount stage.
D.
Ensure that HR_PDB is open.
