2. 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 no other destination is configured for recovery files, then RMAN places the control file autobackups in the
flash recovery area by default.
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 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.Answer:A
3. You defined the Recovery Manager (RMAN) retention policy to recovery window of 7 days by executing the
following command:
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

4. You set the recovery window to seven days and the backup optimization to ON using the CONFIGURE
command of Recovery Manager (RMAN). The most recent backup of the TOOLS tablespace to disk was taken on
January 3. The TOOLS tablespace is read-only.
On February 21, when you execute a command to back up all the tablespaces to disk, you find that RMAN backs
up the TOOLS tablespace also, even though the contents of the tablespace have not changed after the backup on
January 3.
Because there are no changes made to the TOOLS tablespace, you decide that the tablespace should not be backed
up by RMAN. What can you to do skip backing up the TOOLS tablespace without changing the current backup
optimization setting?
A. configure a default device for RMAN backups
B. temporarily disable the retention policy for RMAN backups
C. configure automatic channel allocation for RMAN backups
