What is a primary reason to implement a VLAN?

Implementing a Virtual Local Area Network (VLAN) primarily serves the purpose of managing bandwidth allocation based on user types and needs. A VLAN allows network administrators to segment networks logically, regardless of the physical location of devices. This segmentation enables better management of the network traffic, ensuring that different user groups can be prioritized according to their specific requirements.

For instance, in an organization where certain departments may require more bandwidth for video conferencing or heavy data transfers, VLANs can be configured to allocate sufficient resources to those departments while balancing the needs of other user groups. This management helps to optimize the overall performance of the network and ensures more efficient use of bandwidth.

The other options, while they may have some relevance in different contexts, do not capture the primary function of VLANs. VLANs do not directly increase network speed, resolve hardware costs, or enhance wireless connectivity; instead, they focus on logical segmentation for improved traffic management and user experience.
