Which term refers to the logical segmentation of a network to limit broadcast domains?

• A. Virtual Local Area Network (VLAN)
• B. Virtual Private Network (VPN)
• C. Vmware
• D. VoIP

Answer: (A)

VLANs create multiple broadcast domains by partitioning a physical network into separate, logical networks at the data link layer. By assigning switch ports to different VLANs, devices in the same VLAN share broadcasts, while devices in different VLANs do not receive each other’s broadcasts unless traffic is routed between the VLANs. This containment reduces unnecessary broadcast traffic, enhances security, and simplifies management. Inter-VLAN communication requires routing (a router or layer 3 switch).

The other options don’t fit this concept: a VPN provides secure remote access over public networks, VMware is a virtualization platform, and VoIP is a technology for voice over IP rather than network segmentation.
