Celerra Audit Configuration Files recovery.

I am currently working on studying for the e20-545 exam, and i came across a question that I cannot find any information on. It is asking how audit configuration files are recovered if the control station in slot 1 in replaced. Here is the full question, hoping someone can either tell me how, or point me to a doc that covers this subject.

A customer has replaced the Control Station that was in slot 1. How could the audit configuration files be recovered?

-Manually, re-input using information in the /nas/audit folder

-Automatically, within five minutes of Control Station replacement

-Manually, from the backup files

-Automatically, from the backup files
