Oracle Database 12c: Advanced Administration — Question 2

Examine the RMAN commands executed in your database:
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO disk;
RMAN> CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO BACKUPSET;
RKAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
You issue the command:
RMAN> BACKUP DATABASE;
Which two statements are true about the command?

Answer options

• A. It performs a log switch.
• B. It creates compressed backup sets by using binary compression by default.
• C. It backs up only the used blocks in data files.
• D. It backs up data files, the control file, and the server parameter file.
• E. It creates a backup of only the control file whenever the database undergoes a structural change.

Correct answer: B, E

Explanation

The correct answers are B and E. Option B is accurate because the default behavior of RMAN is to create compressed backup sets using binary compression. Option E is also correct as RMAN backs up the control file during structural changes. Options A, C, and D do not reflect the behavior of the BACKUP DATABASE command in this context.
