You are a senior network administrator for a networking solutions firm. Years ago, you installed a small LAN for the design company. It is growing fast and needs the networking solutions firm to upgrade its network. You assigned Laura to the job. That afternoon, while preparing to work on a lab assignment from her class in Cisco routing, Laura mentions that she would use a switch to implement VLANs to increase the performance of the design companys network because VLANs can be implemented quickly in switches. Explain to Laura when and where a VLAN would be the best choice. Under what circumstances would a VLAN not be the best choice? Provide examples to clarify your points.
