QUESTION 1
A database is running in ARCHIVELOG mode. It has two online redo log groups and each group has one member. A LGWR I/O fails due to permanent media failure that has resulted in the loss of a redo log file and the LGWR terminates causing the instance to crash. Which method should be used to efficiently recover from this loss of the current group member?

A.    Restart the database; it would automatically re-create the corrupted redo log member.
B.    Restore the corrupted redo log group, perform incomplete recovery, relocate by renaming the member of the damaged online redo log group to a new location, and then open the database with RESETLOGS.
C.    Restore the corrupted redo log member, perform incomplete recovery, relocate by renaming the member of the damaged online redo log group to a new location, and then open the database with RESETLOGS.
D.    Restore whole database backup, perform incomplete recovery, relocate by renaming the member of the damaged online redo log group to a new location, and then open the database with the RESETLOGS option.
