Answer
# 1		 
Process of having a copy of redo log files is called mirroring.

This  can be achieved by creating group of log files
together, so that LGWR will  automatically  writes  them to
all the members of the current on-line redo  log  group. If
any one group fails then database automatically switch over
to next group. It degrades performance
