Answer / suresh palanivel
Vlan is logical grouping of n/w users & resources that is
connected administratively to a defined port on a switch.
benefits of Vlan:
1)Provides n/w security
2)Provides Broadcast control.
3)Effiocient usage of bandwidth
4)Phsically you can move the host to any location,it will
remain in same vlan.

Answer / sunilbaglur
Short for virtual LAN, a network of computers that behave
as if they are connected to the same wire even though they
may actually be physically located on different segments of
a LAN. VLANs are configured through software rather than
hardware, which makes them extremely flexible. One of the
biggest advantages of VLANs is that when a computer is
physically moved to another location, it can stay on the
same VLAN without any hardware reconfiguration.

Answer / surjeet gimit
before understand vlan, we must have to understand of the
defination of lan..
{ lan include the all devices in the same broadcast domain}
broadcast domain include the set of lan-connected devices,
when any of the devices send a broadcast frame all the
other devices get a copy of the frame, so think of a lan
and a broadcast basically the same thing.
without vlan, switch consider all its interfaces to be in
the same broadcast domain, in other words all connected
devices are in the same lan.
With vlan, a switch can put some interfaces into one
broadcast domain and some into another creating multiple
broadcast domain. these individual broadcast domain created
by switch are called Vlan.....

Vlan - Virtual Local Area Network
the vlan can group serveral broadcast domains into multiful
logical subnets.
u can accomplish network additions moves and changes by
configurung a port into the appropriate VLAN.
Vlans can enhance network security. Vlans increase the
number of broascast domains while decreasing thir size.
two types vlan 1. static vlan 2. dynamic vlan.

Answer / zgeorgem
Sunilbaglur's answer is right...but this is a software
implementation... there is also a hardware implementation on
switches.... and since Cisco is asking about it this might
be the right answer
VLAN on switches is a feature that allows u to use a single
switch to logically divide their ports so that we can have
different networks on them...
for example if a switch has 32 ports then we can logically
separate 8 ports for network A (or LAN A)
8 ports for network B (or LAN B)
8 ports for network C (or LAN C)
8 ports for network D (or LAN D)
Since switches by default breakup collision domains, VLAN is
a way for them to act like routers by breaking up the
broadcast domain too...

Answer / rohit mahajan
`systems in a network behave like they are connected to same wire but actually they are located at different physical locations. tis type of network doesn't require any hardware reconfiguration if one of the system is moved to different location.
