What is the main advantage of implementing VLANs in a network?

Implementing VLANs (Virtual Local Area Networks) in a network primarily enhances security and traffic management. By segmenting a network into different VLANs, devices that belong to the same VLAN can communicate with one another while being isolated from devices in other VLANs. This isolation improves security by reducing the risk of unauthorized access to sensitive data that may reside on different VLANs.

Additionally, VLANs help in managing network traffic more efficiently. By separating broadcast domains, VLANs help to minimize unnecessary traffic congestion. This allows for better overall network performance as broadcast packets are contained within the VLAN rather than propagated throughout the entire network. Overall, the implementation of VLANs leads to a more organized network structure, where traffic can be managed effectively and securely.
