Which network topology should an administrator use to segment traffic?

• A. Metropolitan Area Networks
• B. Local Area Networks
• C. Virtual Local Area Networks
• D. Wide Area Networks

Answer: (C)

Segmenting traffic on a network is best accomplished with Virtual Local Area Networks, because VLANs create logical broadcast-domain boundaries within the same physical switch fabric. By tagging frames (802.1Q) and grouping devices into distinct VLANs, you can isolate traffic, apply access controls, and reduce unnecessary broadcast traffic without needing separate physical networks. This provides flexible, scalable segmentation across the same switches and cables, and inter-VLAN routing can be used when devices on different VLANs need to communicate. Metropolitan Area Networks describe a city-wide network without addressing segmentation at the local level. Local Area Networks refer to the physical scope of the network, not the method for dividing traffic. Wide Area Networks cover large geographic areas and are about distance, not segmentation strategy.
