An authoritative Nameserver is a nameserver (DNS Server) that holds the actual DNS records (A, CNAME, PTR, etc) for a particular domain/ address. A recursive resolver would be a DNS server that queries an authoritative nameserver to resolve a domain/ address.

Keeping this in consideration, how do I find my authoritative DNS server?
To find out who is responsible for DNS hosting of a domain, you need to find the authoritative DNS servers (or Name Servers) for that domain. A list of DNS servers authoritative for the domain is shown in the Name Server (NS) record. To find this record, you can use the NSLOOKUP tool.
Likewise, what type of DNS server is authoritative for a specific domain? Any DNS server that contains a complete copy of the domain's zone file is considered to be authoritative for that domain only.
Also asked, what is authoritative and Nonauthoritative DNS server?
Non-authoritative name servers do not contain original source files of domain's zone. They have a cache file for the domains that is constructed from all the DNS lookups done previously. If a DNS server responded for a DNS query which doesn't have original file is known as a Non-authoritative answer.
