Because if one server goes down because of some failure then other can handle the work.

In what ways are name servers used?

A name server is the server component of the Domain Name System (DNS). DNS is one of the two main name spaces on the internet. The most important functions of these DNS servers is translating domain names and host names into corresponding numeric IP addresses.

What is stub Zone?

Stub zone When a zone that this DNS server hosts is a stub zone, this DNS server is a source only for information about the authoritative name servers for this zone. The zone at this server must be obtained from another DNS server that hosts the zone. This DNS server must have network access to the remote DNS server to copy the authoritative name server information about the zone. You can use stub zones to: * Keep delegated zone information current. By updating a stub zone for one of its child zones regularly, the DNS server that hosts both the parent zone and the stub zone will maintain a current list of authoritative DNS servers for the child zone. * Improve name resolution. Stub zones enable a DNS server to perform recursion using the stub zone's list of name servers, without having to query the Internet or an internal root server for the DNS namespace. * Simplify DNS administration. By using stub zones throughout your DNS infrastructure, you can distribute a list of the authoritative DNS servers for a zone without using secondary zones. However, stub zones do not serve the same purpose as secondary zones, and they are not an alternative for enhancing redundancy and load sharing. There are two lists of DNS servers involved in the loading and maintenance of a stub zone: * The list of master servers from which the DNS server loads and updates a stub zone. A master server may be a primary or secondary DNS server for the zone. In both cases, it will have a complete list of the DNS servers for the zone. * The list of the authoritative DNS servers for a zone. This list is contained in the stub zone using name server (NS) resource records. When a DNS server loads a stub zone, such as abc.xyz.com, it queries the master servers, which can be in different locations, for the necessary resource records of the authoritative servers for the zone abc.xyz.com. The list of master servers may contain a single server or multiple servers, and it can be changed anytime.

What are the types of DNS zones in windows server 2003?

Primary zoneWhen a zone that this DNS server hosts is a primary zone, the DNS server is the primary source for information about this zone, and it stores the master copy of zone data in a local file or in AD DS. When the zone is stored in a file, by default the primary zone file is named zone_name.dns and it is located in the %windir%\System32\Dns folder on the server.Secondary zoneWhen a zone that this DNS server hosts is a secondary zone, this DNS server is a secondary source for information about this zone. The zone at this server must be obtained from another remote DNS server computer that also hosts the zone. This DNS server must have network access to the remote DNS server that supplies this server with updated information about the zone. Because a secondary zone is merely a copy of a primary zone that is hosted on another server, it cannot be stored in AD DS.Stub zoneWhen a zone that this DNS server hosts is a stub zone, this DNS server is a source only for information about the authoritative name servers for this zone. The zone at this server must be obtained from another DNS server that hosts the zone.

What is a conditional forwarder?

A conditional forwarder is a DNS server configuration that allows a DNS server to forward queries for specific domain names to designated DNS servers. This setup is useful in scenarios where an organization needs to resolve names in a different domain without fully integrating the two networks. By specifying which domains to forward and to which servers, organizations can streamline DNS resolution and improve efficiency for cross-domain queries. Conditional forwarders help maintain separation between different network environments while still enabling necessary communication.

How do you achieve redundancy for your DNS server?

DNS Redundancy is achieved by listing multiple servers, such as NS1.domain.com, NS2.domain.com, in your domain's DNS settings. You must list at least two servers, and can list 4 or more. If you are using a web host they will provide the server names where your web site is hosted for correct DNS locations. The registrar must provide redundant servers to ICCANN for your domain name in order for your web site to be found on the WWW.When a web browser looks for your web site, it searches the web for your server's IP, such as 10.00.00.00, a numerical listing that routes the browser much like the telephone switching system does. If your browser cannot reach the first DNS listed, it will be routed to the next on the list, and the next, if available.

What is DNSDHCPserver?

You are referring to two different severs. A DNS servers and a DHCP server. A DNS server is called a Domain Name Server, it translates IP addresses into English so we can understand it. For instance a website has two names, the IP address 192.168.40.10 and that is matched up to a name in the DNS server such as www.Microsoft.com. So the DNS server gives you the name and vice versa is you wanted to find the IP address of www.Microsoft.com then there is a DNS server that will tell you its 192.168.40.10 (not real address). The DHCP or Dynamic Host Configuration Protocol, is a program that gives you your PC address, such as 192.168.43.99, it is done automatically when you log in, this way your computer has a unique identifier so someone can send you an email and it will only go to you because you have a unique number given to you by your DHCP server.

What would happened if there was not DNS in internet?

Instead of having nice, easy to read, web addresses (google.com), you would have to remember a computer's IP Address (74.125.224.72). Basically, DNS tells yours computer that when you enter Google.com, it needs to connect to 74.125.224.72. It's like remember a houses address instead of it's latitude and longitude. DNS is just a system that relates the two.

What is a member server?

in Active Directory server roles, computers that function as servers within a domain can have one of two roles: member server or domain controller. A member server is a computer that runs an operating system in the Windows 2000 Server family or the Windows Server 2003 family, belongs to a domain, and is not a domain controller. Member servers typically function as the following types of servers: file servers, application servers, database servers, Web servers, certificate servers, firewalls and remote-access servers.

Which two services are required to enable a computer to receive dynamic IP addresses and access the Internet using domain names?

DNS and DHCP
