（602）On Friday at 11:30 am you decided to flash back the database because of a user error that occurred at 8:30 am.

Which option must you use to check whether a flashback operation can recover the database to the specified time?

A. Check the alert log file

B. Query the V$FLASHBACK_DATABASE_LOG view

C. Query the V$RECOVERY_FILE_DEST_SIZE view

D. Query the V$FLASHBACK_DATABASE_STAT view

E. Check the value assigned for the UNDO_RETENTION parameter

答案：（B）

解析：

我们在做闪回数据库的时候，查询V$FLASHBACK_DATABASE_LOG判定你可以闪回的数据库最早的时间，查询v$restore_point;可以查看你有没有还原点，也有可能成为考点
