What is the benefit of using VLANs in a MikroTik configuration?

The benefit of using VLANs (Virtual Local Area Networks) in a MikroTik configuration is that they significantly improve security and traffic management. VLANs enable the segmentation of different types of traffic within a network, allowing for enhanced security by isolating sensitive data and reducing the scope of broadcast traffic. When traffic is segmented, it can be managed more effectively, leading to improved performance and reduced congestion.

By grouping users and devices that require similar access rights into their separate VLANs, network administrators can streamline communication and manage policies more efficiently. Additionally, VLANs provide an ability to apply specific security measures, such as access control lists (ACLs), to restrict access between different VLANs, further enhancing the security posture of the network.

In contrast, the other options do not accurately reflect the key advantages of VLAN technology. Increased cable length is generally not a benefit associated with VLANs; the speed of throughput is more influenced by equipment and network design rather than VLAN configuration itself; while hardware costs may be reduced in some cases due to fewer physical switches being necessary, this is not a primary benefit associated with VLAN implementation. The primary advantages lie in the improved security and traffic management offered by VLANs.
