Your multitenant container database (CDB) cdb1 that is running in archivelog mode contains two pluggable databases (PDBs), pdb2_1 and pdb2_2. RMAN is
connected to the target database pdb2_1.
Examine the command executed to back up pdb2_1:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which statement is true about the execution of this command?
A. It fails because archive log files cannot be backed up using a connection to a PDB.
B. It succeeds but only the data files belonging to the pdb2_i pluggable database are backed up.
C. It succeeds and all data files belonging to PD32_i are backed up along with the archive log files.
D. It fails because the pluggable clause is missing.
