What is a potential benefit of utilizing VLANs in a network?

Utilizing VLANs (Virtual Local Area Networks) in a network provides enhanced network security by allowing the segmentation of network traffic. This isolation means that devices on different VLANs cannot directly communicate with each other unless routed through a specific device, such as a Layer 3 switch or router. By separating sensitive data and users from other parts of the network, VLANs reduce the risk of unauthorized access and limit potential security threats.

For example, a company can create separate VLANs for different departments, like finance and human resources, ensuring that sensitive information within those departments is safeguarded from unintended access by employees in other areas. This segmentation can also allow for more granular control over policies and access, enabling administrators to enforce specific security measures tailored to the needs of each VLAN.

In contrast, the other potential benefits listed do not directly relate to the primary advantages of VLANs. VLANs do not inherently increase data storage; rather, they manage network traffic more efficiently. While VLANs can potentially lead to reduced hardware costs due to less need for physical devices, this is not a direct or guaranteed advantage of implementing them. Finally, VLANs do not extend the internet range; they are focused on internal network management and security rather than affecting external connectivity.
