Consider the following scenario for your database:- Backup optimization is enabled in RMAN.- The recovery window is set to 7 days in RMAN.- The most recent backup to disk for the TOOLS tablespace was taken on November 3, 2007.- The TOOLS tablespace is read-only since November 4, 2007.On November 23, 2007, you issue the RMAN command to back up the database to disk.Which statement is true regarding the backup of the TOOLS tablespace?（）A. The RMAN backup fails because the TOOLS tablespace is read-onlyB. The RMAN skips the backup of the tablespace because backup optimization is enabledC.

You want to take the backup of the USERS tablespace. It has a single data file of 900 MB. You have tape drives of 300 MB each. The SBT channel is configured for Recovery Manager (RMAN).To accomplish the backup, you issued the following RMAN command:RMAN BACKUP SECTION SIZE 300M TABLESPACE users;Which two statements are true about the execution of the above command? （）(Choose two.)A. The backup piece size will be limited to 300 MBB. The RMAN uses multiplexing to perform backupC. The operation is accomplished using the default channel availableD.

You set the recovery window to seven days and the backup optimization to ON using the CONFIGURE command of Recovery Manager （RMAN）.

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 backupsB、temporarily disable the retention policy for RMAN backupsC、configure automatic channel allocation for RMAN backupsD、use the CONFIGURE command to reconfigure the recovery window to 60 days
