第5题：

ou are using the flash recovery area （fast recovery area in 11g Release 2） to store backup related files in your database. After regular monitoring of space usage in the Mash recovery area. You realize that the flash recovery area is （jetting filled up very fast and it is running out of space.  Your database flash recovery area is low on specie and you have no more room on disk. Proactively， which two options could you use to make more space available in the flash recovery（）

• A、 Change the RMAN archived log deletion policy.
• B、 Use the RMAN CROSSCHECK command to reclaim the archived log space.
• C、 Change the RMAN retention policy to retain backups for a shorter period of time.
• D、 Use OS command to move files from the flash recovery area to some other location.

第6题：

You decided to change the location of the flash recovery area. You executed the following command：   ALTER SYSTEM SET DB_RECOVERY_FILE_DEST=’+disk1’ SCOPE=BOTH SID=’*’；   Which statement is true？（）

• A、 The location can be changed only if the flash recovery area is empty.
• B、 After executing the command， all new flash recovery area files will be created in the new location.
• C、 The command will generate an error because you cannot change the flash recovery area while the database is open.
• D、 All the existing files in the flash recovery area will be moved to the new location and all new Flash Recovery Area files will be created in the new location.

第7题：

You have configured the flash recovery area to store online redo log files， control files， archived redo logs and RMAN backups. Which of the following files can you successfully delete from the flash recovery area if you want to reclaim the space within it？（）
