Describe two ways that DNS forwarding can be set up.
What will be an ideal response?
DNS forwarding can be set up so that if the DNS server that receives the forwarded request cannot resolve the name, then the server that originally forwarded the request attempts to resolve it. This is called nonexclusive forwarding. When DNS forwarding is set so that only the DNS server receiving the request attempts resolution (and not the server that forwarded the request), this is called exclusive forwarding. In exclusive forwarding, the DNS server that initially forwards the request is called a slave DNS server.
