For which of the following scenarios would you use user-managed incomplete recovery? (Choose all that apply.)

Answer: A, B, C

Explanation: A is correct because you cannot perform a full recovery with missing archived redo log files. B is correct because incomplete recovery can be performed to bring the database back to a point in time before the severe logical corruptions occurred. C is correct because you can easily copy the database and recover it to a point in time in the past for regression testing. D is incorrect because you can perform complete recovery if you have lost a datafile and have all archived redo log files since the last backup of the datafile . E is incorrect because you do not need to perform recovery if only one copy of the control file is missing.
