What is one benefit of using VLANs in a network?

The benefit of using VLANs (Virtual Local Area Networks) in a network is primarily related to how they manage and segment traffic. By implementing VLANs, you can logically separate different types of network traffic, which helps reduce broadcast domains. This segmentation results in a significant decrease in unnecessary traffic being sent through the network segments, leading to improved overall efficiency.

When devices are grouped into different VLANs, they only communicate with each other unless defined otherwise through a router or Layer 3 switch. This containment minimizes broadcast traffic, which can clutter the network and slow down communication between devices. Therefore, VLANs are effective in optimizing bandwidth and improving network performance by reducing the volume of traffic each device must handle.

Creating distinct VLANs for different departments or services can also lead to enhanced organization and resource allocation within the network. Network administrators can manage the flow of traffic more effectively, resulting in a smoother and faster network experience for users.

While other options might touch on aspects of networking—such as security or physical infrastructure—they do not specifically relate to the primary function and advantage of VLANs, which is traffic management and reduction.
