Be careful with your wording, because even with standby redo logs you can't
ensure zero data loss unless you're running in maximum protection mode.

I would recommend configuring standby redo logs because instead of applying
redo in batches as archive logs arrive at the standby, you can use
real-time apply (requires standby redo logs) to stream redo continuously to
the standby. This generally lowers potential data loss and can also improve
fail over times.

Oh, and while you're busy reading the docs... check out the Data Guard
Broker if you haven't already...
