Use the following Exhibit to answer this question (note: This is not a hacked OCP question. This question
came about out of the experience of one of our junior DBA's that I had to come in and figure out...Several
Sr. DBA's that I know have gotten it wrong already... but we got some smart fokls here! :-)  

RMAN backup. Autobackup of control file is not enabled.  

Time a - Backup of database
Time b - Archivelog Backups
Time c - Drop tablespace
Time d - Archivelog Backup
 

To restore successfully, with RMAN (no manual fiddling) to time point b, you will first need to restore a control file. Which backup would you want to restore the control file from... (more than one answer may well be correct, I'm not telling).  

1. Control file from point a
2. Control file from point b
3. Control file from before point c
4. Control file from after point c
5. Control file from point d
6. Recovery is not possible.

I'll reveal the answer in the next 2 days...(and this *IS* a trick question, so
think carefully).

Clark Griswold: Eddie, has anyone ever told you that you're bad luck? Cousin Eddie: Those were my mother's dying words. But I guess if your body's covered in third degree burns, and your foot's caught in a bear trap, you tend to start talkin' crazy.
