You need to perform a block media recovery on the tools01.dbf data file in the SALES database by using Recovery Manager (RMAN).Which two are the prerequisites to perform this operation? ()(Choose two) A. You must configure block change tracking fileB. You must have first level 1 backups for RMAN to restore blocksC. You must ensure that the SALES database is mounted or openD. You must have full or level 0 backups for RMAN to restore blocksE. You must take the tools01.dbf data file offline before you start a block media recovery
Which of the following statements is NOT true about RMAN？（）A、It improves usability by enabling you to reuse the scripts to perform recovery operations.B、It detects block corruption while restoration and recovery operations.C、It enables you to perform block media recovery.D、It is capable to recover through unrecoverable operations， with only full database backups.
Which of the following is the MOST important step in any disaster recovery plan？（）A、 Appropriate use of backup media and offsite storageB、 The disaster recovery testing process过程C、 Classifying systems according to operational impactD、 Use appropriate fire suppressant systems
What are the two advantages of RMAN Block Media Recovery （BMR） over file/x7flevel recovery？（）A、BMR lowers the mean time to recover （MTTR）.B、BMR supports pointintime recovery of individual data blocks.C、BMR enables you to use incremental backups for block recovery.D、BMR enables recovery even when the database is not mounted or open.E、BMR enables you to use proxy backups to perform block media recovery.F、BMR enables increased availability of data during recovery because the data file that requires a recovery can remain online.
As a result of a media failure， the current online redo log group is corrupted. The database crashes， as the current online group is inaccessible. Which type of incomplete recovery are you most likely to perform？ （）A、Cancel-basedB、Recovery using a backup control fileC、Time-basedD、Change-based
You are performing a block media recovery on the tools01.dbf data file in the SALES database by using RMAN. Which two statements are correct in this scenario？（）A、You must ensure that the SALES database is mounted or open.B、You must restore a backup control file to perform a block media recovery.C、You must take the tools01.dbf data file offline before you start a block media recovery.D、You must put the database in NOARCHIVELOG mode to perform a block media recovery.E、You can perform only a complete media recovery of individual blocks； point-in-time recovery of individual data blocks is not supported.

多选题In your database， all the tablespaces are locally managed. You started Recovery Manager （RMAN） using recovery catalog and restored the control file by using the following command： RMAN RESTORE CONTROLFILE； Which two operations do you need to perform after restoring the control file from backup？（）Ashut down and restart the instanceBadd new tempfiles to the temporary tablespaces after recoveryCperform a media recovery and open the database with the RESETLOGS optionDperform a media recovery and bring the database to NOARCHIVELOG mode
多选题Media recovery can sometimes be stopped by the inability to read past a certain point in the redo stream. This is often referred to as “stuck recovery”. Before Oracle9i， the Database Administrator had few options to deal with stuck recovery. If the corrupt redo could not be recovered from some other source， then all transactions that committed after the corrupt point in the redo steam would be lost. Oracle9i changes that with the Trial Recovery feature. Trial Recover is used to test the application of the redo logs to the database. What are three other characteristics of Trial Recovery（）ASpeeds up subsequent media recover actions.BWrites any uncorrupted block to disk during the test recovery.CCan be invoked by adding the TEST option to any RECOVER command.DAllows the Administrator to determine how many blocks are affected by corruption.EMarks blocks as corrupt in memory， allowing the test recover to proceed to completion.
多选题You noticed that the index tablespace in your database requires a recovery. However， instead of performing a media recovery， you decided to re-create the indexes in a new tablespace. Which two options would you use to reduce the time it takes to re-create the indexes？（）AONLINEBREVERSECPARALLELDCOMPRESSENOLOGGINGFCOMPUTE STATISTICS
