https://oracle-base.com/articles/12c/multitenant-rman-backup-recovery-cdb-and-pdb-12cr1 Archived Redo Log Backups Redo is managed at the root container level. There is no concept of redo from the PDB perspective, but of course any changes in tablespaces owned by the root container or a user-defined PDB are protected by redo in the normal manner. As a result, you will never perform a PDB-level archived redo log backup, because there are no PDB-specific redo logs. Instead, you will do your archived redo log backups in the normal way from the root container. They can be done along with the database backups or as a separate operation, as shown below. $ rman target=/ RMAN> BACKUP DATABASE PLUS ARCHIVELOG; RMAN> BACKUP ARCHIVELOG ALL; Answer is B

C? Found this in the Docs: Create a full backup of the PDB including the archived redo log files. If RMAN backups of the PDB already exist, then these backups are usable after the PDB is migrated to another destination CDB. However, it is recommended that you back up the archived redo log files. The following command backs up the PDB when you are connected to the PDB as a local user with the SYSDBA or SYSBACKUP privilege: RMAN> BACKUP DATABASE PLUS ARCHIVELOG ALL TAG for_migration; Ref: https://docs.oracle.com/en/database/oracle/oracle-database/19/bradv/backing-up-database.html#GUID-E5A3E523-C55C-4666-8334-81E7A224371B

B is the right answer

C is correct. Note that the PLUS ARCHIVELOG clause performs the following: Runs the ALTER SYSTEM ARCHIVE LOG CURRENT command Runs the BACKUP ARCHIVELOG ALL command. If backup optimization is enabled only backs up logs that have not already been backed up. Backs up files specified in the BACKUP command Runs the ALTER SYSTEM ARCHIVE LOG CURRENT command Backs up any remaining archived logs including those generated during the backup

Definitely B，PDB is same as non-CDB for user,so they won't know which kind of database will be backedup,it must be success

B is the correct answer
