Oracle Database 12c: Advanced Administration — Question 176

You issue the RMAN commands:
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO disk;
RKAN> CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COPY;
RMAN>CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which three tasks are performed by the BACKUP DATABASE command?

Answer options

• A. switching the online redo log file
• B. backing up all data files as image copies and archive log files, and deleting those archive log files
• C. backing up only the used blocks in the data files
• D. backing up all used and unused blocks in the data files
• E. backing up all archived log files and marking them as obsolete

Correct answer: A, C, E

Explanation

The BACKUP DATABASE command performs three key tasks: it switches the online redo log file (A), backs up only the used blocks in the data files (C), and backs up all archived log files while marking them as obsolete (E). Options B and D are incorrect because the command does not create image copies of all data files nor does it back up unused blocks.
