1. What is Domain?
Ans: The term domain can refer either to a local subnetwork or to descriptors for sites on the
Internet e.g. www.jetking.com
2. What is Workgroup?
Ans: A workgroup is a collection of computers on a local area network (LAN) that share
common resources and responsibilities. Being a peer-to-peer (P2P) network design, each
workgroup computer may both share and access resources if configured to do so.
3. What is use of domain controller?
Ans:- The primary function of domain controllers is to validate users to the network.
However, domain controllers also provide the catalog of Active Directory objects to users on
the network.
4. What is DNS?
Ans: DNS stands for Domain Name System which provides for the local mapping of fully
qualified domain names to IP addresses
5. What is DHCP
Ans: Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that enables a
server to automatically assign an IP address to a computer from a defined range of numbers
(i.e., a scope) configured for a given network.
6. What is DNS & why we used ?
Ans: DNS is simply a database that links host names, such as http://www.jetking.com, to a
specific IP address, such as 192.168.124.1. Apart from this, DNS has many more features.
The key features of host name to IP mapping are as follows:



Mappings of addresses to names and vice versa (known as records) are stored in a
database.
The DNS database is distributed.
A DNS database also stores additional records.
7. Working process of DNS
Ans: When a DNS client needs to look up a name used in a program, it queries DNS servers
to resolve the name. For example, the name specified could be the FQDN for a computer,
such as "mumbai.jetking.com.", DNS queries resolve in a number of different ways. A client
can sometimes answer a query locally using cached information obtained from a previous
query. The DNS server can use its own cache of resource record information to answer a
query. A DNS server can also query or contact other DNS servers on behalf of the requesting
client to fully resolve the name, then send an answer back to the client. This process is known
as recursion.
In addition, the client itself can attempt to contact additional DNS servers to resolve a name.
When a client does so, it uses separate and additional nonrecursive queries based on referral
answers from servers. This process is known as iteration.
In general, the DNS query process occurs in two parts:

A name query begins at a client computer and is passed to a resolver, the DNS Client
service, for resolution.

When the query cannot be resolved locally, DNS servers can be queried as needed to
resolve the name.

Ans: From the Network Administration group, start DHCP Manager. Under DHCP Servers,
select *Local Machine*. From the Scope menu, choose Create. Complete the scope
configuration. The DHCP server cannot be a DHCP client. It must have a static IP address,
subnet mask, and default gateway address. You also have the option of assigning an
exclusion range or specific excluded addresses as well as lease duration and a name. Choose
OK when done. Choose Yes to activate the scope.
How to configure DNS?
Ans: Open the DNS console. Highlight your computer name and choose Action | Configure a
DNS Server… to launch the Configure DNS Server Wizard. Click Next and choose to
configure the following: forward lookup zone, forward and reverse lookup zone, root hints
only. Click Next and then click Yes to create a forward lookup zone. Click Next and type the
name of the zone you are creating. Click Next and then click Yes to create a reverse lookup
zone. Choose whether you want an IPv4 or IPv6 Reverse Lookup Zone. Click Next and enter
the information to identify the reverse lookup zone. You can choose to create a new file or
use an existing DNS file On the Dynamic Update window, specify how DNS accepts secure,
nonsecure, or no dynamic updates. If you need to apply a DNS forwarder, you can apply it on
the Forwarders window. Click Finish
What is VPN
Ans: VPN stands for Virtual Private Network which is a virtual network of computers that
uses a public telecommunication infrastructure and provides a user with secure remote access
to the network resources.
What is database server
Ans: A database program such as MySQL or Oracle which is hosted on a server that provides
database services to other computer programs or computers, is known as database server. The
term may also refer to a computer dedicated to running such a program.
In printer password is required or not
Ans: Yes, required
How to share a printer in network?
Ans: If you currently have a printer already installed on the computer right-click the printer
icon and click Properties. Click the Sharing tab and make sure the printer is shared. Or by

Types of server
Ans: E-mail server, database server, file server, mail server, print and web server
Dial up connection, explain it
Ans: It is a form of Internet access that uses public switched telephone network (PSTN)
using telephone line to connect to an Internet service provider (ISP)
What is mail server
Ans: A mail server also known as a mail transfer agent or MTA, is an application that
receives incoming e-mail from local users (people within the same domain) and remote
senders and forwards outgoing e-mail for delivery. A server dedicated to running such
applications is also called a mail server.
What is login script

on. These instructions are held on the server in a 'script' file, which is a batch file that
workstations can access and run.
How can create Domain member
Ans: Domain members can be created through the Active Directory Users and Computers
snap-in. You can also create client computer accounts via the client computer by joining it to
the domain via the System Properties dialog box. This requires a user account that has
administrative privileges, such as members of the Domain Administrator or Enterprise
Administrator groups.
19. What is WINS and full form of Wins
Ans: WINS stands for Windows Internet Naming Service, supports name resolution, converts
NetBIOS names to IP addresses for Windows networks.
20. How to connect PC in server / Domain
Ans: You can join to the domain via the System Properties dialog box. This requires a user
account that has administrative privileges, such as members of the Domain Administrator or
Enterprise Administrator groups.
21. What is the use of Active directory
Ans: It is a directory service created by Microsoft for Windows domain networks. It is used
to authenticate and authorize all users and computers in a Windows domain type network—
assigning and enforcing security policies for all computers and installing or updating
software.
22. What is ADDS and its use
Ans: ADDS stands for Active Directory Domain Services are the foundation for distributed
networks built on Windows 2000 Server, Windows Server 2003 and Microsoft Windows
Server 2008 operating systems that use domain controllers. It provides secure, structured,
hierarchical data storage for objects in a network such as users, computers, printers, and
services.
