To recover from the loss of the entire database, including all current control files, all online redo log files, and all parameter files, what backups are required, at a minimum, torestore the database successfully? (choose all that apply.)

Answer: A, B, D

Explanation: To recover your database fully, you need a backup of all datafiles, all archived log files created since the last datafile backup, and an autobackup of the control file. c and e are incorrect because you can easily re-create the password file, and rman creates a dummy spfile during recovery.
