You can have 2 (and no more than 2) servers in a failover pair per pool. You essentially clone the config file from the primary to the secondary - and add the relevant failover peer declarations.

Yes, that's how it works

It's internal. When one server issues a lease, it notifies the other which updates it's local lease file.
