Which of the following is a key advantage of using VLANs in a network?

Using VLANs (Virtual Local Area Networks) in a network is particularly beneficial for the separation of network traffic, which leads to better management. By segmenting network traffic, VLANs help in organizing the network into smaller, manageable sections based on specific criteria such as department or function. This traffic separation reduces broadcast domains and limits the spread of broadcast traffic, which can lead to improved performance and security within the network.

In a typical network environment, different types of traffic can lead to congestion and management challenges. With VLANs, network administrators have the flexibility to assign various devices to different VLANs based on their roles, which creates isolated environments. This isolation allows for more straightforward troubleshooting and better control over network policies applied to each segment, enhancing overall network efficiency.

Furthermore, this separation aids in the application of security policies. Sensitive devices can be placed on a separate VLAN, minimizing exposure to other network threats. Overall, this strategic organization through VLANs ultimately streamlines network management and enhances performance.

While the other choices mention various benefits of networking, they do not specifically capture the core advantage of VLANs in promoting traffic separation and thus improved management.
