Describe the two types of DNS servers.
What will be an ideal response?
The two types of DNS servers are authoritative and cache-only. An authoritative DNS server maintains a list of all the host names and IP addresses for an entire domain. A cache-only server does not store any FQDNs in a database as an authoritative DNS server would, but it does resolve IP addresses for DNS clients, and stores recently resolved names and addresses in a cache of a configurable size.
