45. On Tuesday, a junior DBA dropped an important application user ac
count, whose schema has important tables. You are asked to recover al
l the objects in the schema. On investigation, you find that the user
account was dropped at 11:00 a.m. and Sunday's backup is the most re
cent backup. Which flashback feature would you use?
A. Flashback Drop
B. Flashback Table
C. Flashback Database
D. Flashback Version Query
E. Flashback Transaction Query
Answer: C
Flashback Database 类似rman 的不完全恢复,它可以把数据库回退到过去某
个时间点的状态.
Flashback Drop 只是恢复单个table
