Ans: load balancing, fault tolerance.
12)what is caching only server?
Ans: Caching only servers does not stores only zones.it resolves host names
To IP address for client computers and stores the resulting mapping information in it’s cache. this DNS server provides the cached information to the client computer with contacting other DNS servers to resolve the query.
It is the temporary storage of zone information.
13)what is zone transfer?
Ans: The process of copying zone to a standard DNS server is called zone transfer.
14)what is master DNS server?
Ans: As the DNS contains the master copy of the zone information is called Master DNS.

Ans: -msdcs: (Microsoft Domain controller service)
It contains the information which domain controller is hosting the zone.
Site: In which site the zone has been configured.
Tcp& Udp: These are two protocols that are responsible for communicating with active directory.
Domain DNS Zones & Forest DNS Zones:
In which domain & Forest, DNS has be configured the information.
19) What is Resource record?
Ans: The entries are in zone is called Resource record. The entry may be host name IP address mapping entry.
20) What is the primary thing you have to do on a DNS server before it starts resolution of host name?
21) When will you configure root DNS server?
Ans: : A root server should be used only when a network is not connected to the internet or when a network is connected to the internet or when a network is connected to the internet by using a proxy server

Ans: Standard primary DNS server stores DNS entries(IP address to host mapping and other DNS resource records ) in zone file that is maintained on the server. The primary server maintains the master copy of zone file. When changes need to be the zone they should be made only standard primary server.
25)what is standard secondary zone?
Ans: Standard secondary DNS server stores copies of zones from the standard primary.
26) what is root server?
Ans:Root server contains a copy of a zone for the root domain – either the root domain for the internet, or the root domain for a company private, internal network. the purpose of the root server is to enable other DNS servers on a network to access the second level domains on the internet.
Note: A root server should be used only when a network is not connected to the internet or when a network is connected to the internet or when a network is connected to the internet by using a proxy server

Ans:Root hints are server names and ip address combination that point to the root servers located either on the internet or on your organization private network.
Root hint tab contains list of DNS Servers can contract to resolve client DNS queries.
Maintains all the information of 13 root servers.
32)what is Active Directory integrated zone?
Ans: Active directory integrated DNS server just like standard primary except DNS entries stored in active directory data store rather than in a zone file. Active directory supports multi master replication when changes need to be made to the zone. They can be on any active directory –integrated DNS server that containg the zone.
33)what is simple query?
Ans: A simple query is a query that DNS server can resolve without contacting any other DNS servers.
34) what is recursive query?
Ans: a recursive is a query that can’t resolve it self it must be contract one or more additional DNS servers to resolve the query.

PTR: Pointer resource record
SRV: Service locator resource record

36)What is SRV?
Ans: Used to map specific service (tcp/ip) to list of servers that provide that service.

Ans: stub zone contains the information of Name Server & start of authority. It gives the information in which system, in which server, in which domain DNS has been configured
The properties of DNS in Advanced Tab
(Disable Recursion or disable forwarder)
By default this option is unchecked telling that recursive property
is present.
BIND Secondaries:
The zone transfers between the primary & secondary (replication between primary and secondary) BIND is responsible.
Fail on load if bad zone data:
This option is unchecked telling that even if the zone contains some errors it will be loaded if it is checked the zone will not be loaded.
Enable Round Robin:
If the same zone is present in the same subnet the query will be passed on round robin passion until it gets resolved.
Enable Net Mask ordering:
This option is utilized for DNS Server maintained on multihome pc (A pc having multiple NIC cards) and solving the queries of diff clients subnets
Secure cache against pollution:
It secures the cache information by not storing the information of unauthorized DNS servers.
