What is the primary use of VLANs (Virtual Local Area Networks)?

• A. To segment network traffic
• B. To enhance network security only
• C. To allow for faster wireless connections
• D. To increase internet speed

Answer: (A)

The primary use of VLANs (Virtual Local Area Networks) is to segment network traffic. VLANs allow network administrators to create logically separate networks within a single physical network. This segmentation helps manage and control traffic more efficiently by grouping together devices that need to communicate frequently, regardless of their physical location. By creating VLANs, different departments or groups within an organization can be isolated from each other, which reduces broadcast traffic and enhances overall network performance. This logical separation also simplifies management tasks, such as applying policies or configurations tailored to specific groups. For instance, voice, data, and management traffic can each reside on their own VLAN, improving organization and security. The other options focus on specific benefits of VLANs but do not encompass their primary purpose. While VLANs can contribute to enhanced network security, they are not solely dedicated to that function. Similarly, VLANs do not inherently impact the speed of wireless connections or increase internet speed; their main function is traffic segmentation and organization within the network.
