When you perform a whole database backup with the command BACKUP DATABASE PLUS ARCHIVELOG, which database objects are included in the backup? (Choose the best answer.)

Answer: B

Explanation: The command backs up all datafiles plus the archived log files. It backs up the SPFILE if you include the SPFILE keyword, and it backs up the control file if autobackup of the control file is configured. A is incorrect because no such CONTROLFILE keyword exists, and you cannot specify autobackup of the SPFILE alone. C is incorrect because archived log files are deleted only if you include the DELETE INPUT option. D is incorrect because configured RMAN settings specify other files included in the backup.
