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?() 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.
