Networking Interview Questions

What is remote desktop?

A feature that's allow user to manage computers remotely.
On server side
My computer ==> properties ==> remote ==> Tick mark on this check box allow user to connect this computer remotely ==> select user. 
On client 
start ==> program ==> accessories ==> communication ==> remote desktop ==> Server ip ==> user name and password configured on server. 
Role of server side can be played only by XP professional or server2003.

How will you make dial-up connection ?

Physical installation of modem ==> install modem driver ==> my network place ==> properties ==> Make new connection ==> next ==>connection to internet ==> setup my connection manually ==> Connect using a dial up modem

How will you share printer ?

Install local printer on that pc which has physically attached printer. And then Right click on it ==> share ==> In xp if you run small office set wizard it will be share automatically. On all other PC install network printer. While installing printer choose network printer.

How will you configure broadband ?

There are two type of broadband available

One that required user name and password to connect the internet like BSNL or Reliance for this type of connection Physical installation of modem ==> my network place ==> properties ==> Make new connection ==> next ==> connection to internet ==> setup my connection manually ==> Connect using a broadband connection that requires a user name and password ==> ISP name ==> User name and password ==> add a short cut to desktop 
If you are using other type of connection like Airtel for this type of connection you don't required any additional configuration 
If DHCP is enable in modem 
IP address and DNS setting will be automatically configure. 
If DHCP is not enable then set it manually as given ip by provider

What is minimum requirement of RAM for installation of XP?

64 MB

What is firewall?

The primary method for keeping a computer secure from unauthorized user. A firewall allows or blocks traffic into and out of a private network or the user's computer. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network. 
XP pack 2 has a built in firewall that is enabled by default. To change the setting of it use this path
Local area network ==> properties ==> advance ==> setting

What is Active Directory?

Active Directory is a network-based object store and service that locates and manages resources, and makes these resources available to authorized users and groups. An underlying principle of the Active Directory is that everything is considered an object—people, servers, workstations, printers, documents, and devices. Each object has certain attributes and its own security access control list (ACL).

Workers are not able to print from the printer, there user logon are correct and are allowed to print from that printer in active directory. How would you resolve this issue?

1. Verify printer is set as default.
2. Verify users have local privileges set properly to print.
3. Is print server delivering correct drivers.
4. Is local naming convention for printer correct.
5. If pre Win2000 workstation, naming convention must be less than 12 characters.
6. Make sure no viruses present. Some Viruses can shut down IPC shares and printing services.

Where are the Windows NT Primary Domain Controller (PDC) and its Backup Domain Controller (BDC) in Server 2003?

The scheme of PDC and BDC is replaced by The Active Directory in server 2000 and further. Now all domain controllers share a multi master peer-to-peer read and write relationship that hosts copies of the Active Directory.

How can group policy be refreshed?

1. Restart the server
2. Leave the server ideal for 90 minute
3. Run ==> gpupdate (server 2003 only)

What is LILO?

LILO stands for Linux boot loader. It will load the MBR, master boot record, into the memory, and tell the system which partition and hard drive to boot from.

I can't seem to access the Internet, don't have any access to the corporate network and on IP configuration on my address is 169.254.*.*. What happened?

The 169.254.*.* net mask is assigned to Windows machines running 98/2000/XP if the DHCP server is not available. The name for the technology is APIPA (Automatic Private Internet Protocol Addressing).

We've installed a new Windows-based DHCP server, however, the users do not seem to be getting DHCP leases off of it.

The server must be authorized first with the Active Directory.

What's the difference between local, global and universal groups?

Domain local groups assign access permissions to domain groups for local domain resources. Global groups provide access to resources in entire domains.

What's the major difference between FAT and NTFS on a local machine?

FAT and FAT32 provide no security over locally logged-on users. Only native NTFS provides extensive permission control on both remote and local files.

What is presentation layer and how it is responsible for in the OSI model?

The presentation layer establishes the data format prior to passing it along to the network application's interface. TCP/IP networks perform this task at the application layer

Networking Interview question

When were OSI model developed and why its standard called 802.XX and so on?

OSI model was developed in February1980 that why these also known as 802.XX Standard (Notice 80 means ==> 1980, 2means ==> February)

What is Full form of ADS?

Active Directory Structure

How will you register and activate windows?

If you have not activated windows XP, you can do so at any time by clicking the windows Activation icon in the system tray to initiate activation. Once you have activated windows XP, this icon disappears from the system tray. 
For registration 
Start ==> Run ==> regwiz /r

Where do we use cross and standard cable?

Computer to computer ==> cross 
Switch/hub to switch/hub ==>cross 
Computer to switch/hub ==>standard

How many pins do serial ports have?

In computer it's known as com port and could be available in 9pin or 25 pin. On router it have 60 pins.

How will check ip address on 98?

Start ==> Run ==> command ==> winipcfg

How will you make partition after installing windows?

My computer ==> right click ==> manage ==> disk management ==> 
select free space ==> right click ==> New partition

What is IP?

It's a unique 32 bits software address of a node in a network.

What is private IP?

Three ranges of IP addresses have been reserved for private address and they are not valid for use on the Internet. If you want to access internet with these address you must have to use proxy server or NAT server (on normal cases the role of proxy server is played by your ISP.).If you do decide to implement a private IP address range, you can use IP addresses from any of the following classes: 
Class A 10.0.0.0 10.255.255.255 
Class B 172.16.0.0 172.31.255.255 
Class C 192.16.8.0.0 192.168.255.255

What is public IP address?

A public IP address is an address leased from an ISP that allows or enables direct Internet communication.

What's the benefit of subnetting?

Reduce the size of the routing tables. 
Reduce network traffic. Broadcast traffic can be isolated within a single logical network. 
Provide a way to secure network traffic by isolating it from the rest of the network.

What are the differences between static ip addressing and dynamic ip addressing?

With static IP addressing, a computer (or other device) is configured to always use the same IP address. With dynamic addressing, the IP address can change periodically and is managed by a centralized network service

What is APIPA?

Automatic private IP addressing (APIPA) is a feature mainly found in Microsoft operating systems. APIPA enables clients to still communicate with other computers on the same network segment until an IP address can be obtained from a DHCP server, allowing the machine to fully participate on the network. The range of these IP address are the 169.254.0.1 to 169.254.255.254 with a default Class B subnet mask of 255.255.0.0.

What are the LMHOSTS files?

The LMHOSTS file is a static method of resolving NetBIOS names to IP addresses in the same way that the HOSTS file is a static method of resolving domain names into IP addresses. An LMHOSTS file is a text file that maps NetBIOS names to IP addresses; it must be manually configured and updated.

What is DHCP scope?

A scope is a range, or pool, of IP addresses that can be leased to DHCP clients on a given subnet.

What is FQDN?

An FQDN contains (fully qualified domain name) both the hostname and a domain name. It uniquely identifies a host within a DNS hierarchy

What is the DNS forwarder?

DNS servers often must communicate with DNS servers outside of the local network. A forwarder is an entry that is used when a DNS server receives DNS queries that it cannot resolve locally. It then forwards those requests to external DNS servers for resolution.

Which command will you use to find out the name of the pc in networks?

NSLOOKUP [192.168.0.1] 
[Ip of target computer]

How will enable sound service in 2003?

By default this service remain disable, to enable this service
Start ==> administrative tools ==> service ==> windows audio ==> start up type ==> automatic

How will enable CD burning service in 2003?

By default this service remain disable, to enable this service
Start ==> administrative tools ==> service ==> IMAPI CD burning com service ==> start up type ==> automatic

What are basic and dynamic disks?

What are basic and dynamic disks?

Basic disks and dynamic disks are two types of hard disk configurations in Windows. Most personal computers are configured as basic disks, which are the simplest to manage. Dynamic disks can make use of multiple hard disks within a computer to duplicate data for increased performance and reliability. 
A basic disk uses primary partitions, extended partitions, and logical drives to organize data. A formatted partition is also called a volume (the terms volume and partition are often used interchangeably). In this version of Windows, basic disks can have either four primary partitions or three primary and one extended partition. The extended partition can contain an unlimited number of logical drives. The partitions on a basic disk cannot share or split data with other partitions. Each partition on a basic disk is a separate entity on the disk. 

Dynamic disks can contain an unlimited number of dynamic volumes that function like the primary partitions used on basic disks. The main difference between basic disks and dynamic disks is that dynamic disks are able to split or share data among two or more dynamic hard disks on a computer. For example, a single dynamic volume may actually be made up of storage space on two separate hard disks. Also, dynamic disks can duplicate data among two or more hard disks to guard against the chance of a single disk failing. This capability requires more hard disks, but improves reliability.

Older Compaq computers such as the Deskpro 286 or 386	Place the diagnostics disk in the disk drive, reboot your system, and choose Computer setup from the menu
Newer Compaq computer such as the Prolinea, Deskpro, Deskpro XL, Deskpro XE, or Presario	Press the F10 key while the cursor is in the upper-right corner of the screen, which happens just after the two beeps during booting*
All other older computers	Use a setup program on the disk that came with the PC

* For Compaq computers, the CMOS setup program is stored on the hard drive in a small, non-DOS partition of about 3 MB. If this partition becomes corrupted, you must run setup from a bootable CD or floppy disk that comes with the system. If you can not run setup by pressing F10 at startup, suspect a damaged partition or a virus taking up space in conventional memory.
