  Virtual LANs is a L2 technique used to segregate users in a LAN(per say , seggregation of broadcast domain) . Now when I say L2, everyone relates it to a switch. The tricky question being- what is the difference between a L2 VLAN and L3 VLAN.

  I am not sure much about L3 VLAN. But for communication between two or more L2 VLAN they required to go to L3. Some modern Switches can also work at L3, means they can route the packets also.

  VLANs will allow LAN administrators to "fine tune" their networks by logically grouping users. Software configurations can be made uniform across machines with the consolidation of a department's resources into a single subnet. IP addresses, subnet masks, and local network protocols will be more consistent across the entire VLAN. Fewer implementations of local server resources such as BOOTP and DHCP will be needed in this environment. These services can be more effectively deployed when they can span buildings within a VLAN.
  
  Thanks in advance.
