Which DNS servers are at the highest level of the DNS namespace?
the root domainDNS namespace: DNS is the name service provided by the Internet for TCP/IP networks. DNS is broken up into domains, a logical organization of computers that exist in a larger network. The domains exist at different levels and connect in a hierarchy that resembles the root structure of a tree. Each domain extends from the node above it, beginning at the top with the root-level domain. Under the root-level domain are the top-level domains, under those are the second-level domains, and on down into subdomains. DNS namespace identifies the structure of the domains that combine to form a complete domain name. For example, in the domain name sub.secondary.com, "com" is the top-level domain, "secondary" identifies the secondary domain name (commonly a site hosted by an organization and/or business), and "sub" identifies a subdomain within the larger network. This entire DNS domain structure is called the DNS namespace. The name assigned to a domain or computer relates to its position in the namespace.
What administrative entity you create on a dns server to represent a discrete portion of the dns namespace?
A zone.
What DNS component was introduced to eliminate the large amount of processing time required to perform reverse lookups?
in-addr.arpa domain Before reverse lookups were introduced, DNS needed to search all the domains in the DNS namespace to identify the hostname corresponding to an IP address. This took a large amount of processing time. To overcome this problem, the in-addr.arpa domain was created, which contains the required DNS records for reverse lookups. The in-addr.arpa domain is a reserved Internet DNS namespace.
What is the difference between a zone and a domain?
A domain is a portion of the overall DNS namespace. A zone, however, can contain multiple contiguous domains.
What is DNS root hints?
A DNS root zone is the top-level DNS zone in a Domain Name System (DNS) hierarchy
What do the DNS servers do with the information learned from the iterative queries?
An iterative name query is one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS server for which it obtained a referral. It continues this process until it locates a DNS server that is authoritative for the queried name, or until an error or time-out condition is met.This process is sometimes referred to as "walking the tree," and this type of query is typically initiated by a DNS server that attempts to resolve a recursive name query for a DNS client.
What is the purpose of a root server in DNS?
If a DNS server cannot find the answer to the DNS Query in its own database it will first query the forwarders (if there are any configured) and then ask the root server. root servers (by default) are the master DNS servers of the Internet. The are called A, B, C, ... These are the highest level of the DNS hierarchy. Ultimately, any DNS request that can't be solved at a lower level (through the use of a cache) is traced back to those 13 root servers. Them root server in general is . .com,.org etc but in your domain the first dc in the forest/domain is the one
