12. Your database is configured in archivelog mode.
Examine the RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO COPY;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
Examine the command:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which 2 are true?
A) It fails because the delete input option can be used only with the backup as backupset command.
B) It falls because the delete input option can be used only with the backup as copy command.
C) It creates image copies of the archivelogs.
D) It creates image copies of the database files.
E) It creates a backupset of archive log files
Answer：CD
