Question 1

Explanation

All DNS servers fall into one of four categories: Recursive resolvers, root name servers, TLD name servers, and authoritative name servers. In a typical DNS lookup (when there is no caching in play), these four DNS servers work together in harmony to complete the task of delivering the IP address for a specified domain to the client (the client is usually a stub resolver – a simple resolver built into an operating system).
