Authoritative means configured and authorized to provide information regarding a DNS request for a host record.

Their are two types of queries:

1) a query for a zone record for which a server is authoritative and that server can answer directly

2) a query for a zone record for which a server is not authoritative -- this is also called "recursion" and for which the server must search up the tree to find an authoritative DNS server to provide an answer.

Absolutely.

You would configure the zone files for which you are authoritative, use a root hints file and allow your subnets to use your server to resolve external hosts.
