Yes.  Look at the "forward-zones" and "forward-zones-file" options.

Yes if you have internal-only domains which are not visible on the 
public Internet (i.e. there are no NS records pointing to the 
authoritative nameservers, and/or the authoritative nameservers are not 
reachable from the Internet)

A better performance solution than what?

You cannot simply point the clients directly at an authoritative server; 
you must point them at a recursor.  Actually, pdns authoritative used to 
have a built-in recursor option, but this was removed in 4.1.0.

One final hint: if you're on Ubuntu 16.04, make sure that you're not 
using the pdns auth server in the Ubuntu repositories. It is an alpha 
release which is buggy.  Use the repositories at https://repo.powerdns.com/

HTH,
