You issued the following commands to configure setting in RMAN;RMAN CONFIGURE DEVICE TYPE sbt PARALLELISM 1;RMAN CONFIGURE DEFAULT DEVICE TYPE TO sbt;RMAN CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE sbt TO 2;RMAN CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE sbt TO 2;RMAN CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;Then you issued the following command to take the backup:RMAN BACKUP DATABASE PLUS ARCHIVELOG;Which statement is true about the execution of the above command?（）A. The backup will terminate because the FORMAT clause was not configured for the channelB. It backs up two copies of data files to tape and disk, and two copies of archived log file on tapeC. It backs up the data files and archived log files to disk, making two copies of each data file and archived log fileD.

考题
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/x7fonly. 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 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
