第16题：

The database is running in ARCHIVELOG mode and the FORMAT option is not configured in RMAN for disk backups. You configured the flash recovery area location and size by using the DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE initialization parameters. Which statement is correct in this scenario？（）

• A、 If the FORMAT option to the RMAN BACKUP command is specified， then RMAN creates backup pieces and image copies in the flash recovery area with names in the Oracle Managed Files （OMF） format.
• B、 If any local destinations for LOG_ARCHIVE_DEST_n are set， then archived redo logs are stored in these destinations as well as in the flash recovery area.
• C、 If the flash recovery area location is configured using the DB_RECOVERY_FILE_DEST initialization parameter， then the RMAN backup of Oracle managed datafiles （OMF） only will go to the flash recovery area by default.
• D、 If no other destination is configured for recovery files， then RMAN places the control file autobackups in the flash recovery area by default.

第17题：
