What is one reason a network administrator would segment a network with a Layer 2 switch?

• A. To increase broadcast traffic
• B. To enhance user bandwidth
• C. To simplify network design
• D. To eliminate the need for routing

Answer: (B)

Segmenting a network with a Layer 2 switch primarily enhances user bandwidth by creating smaller collision domains. When devices are connected through a switch, each connection operates within its own collision domain, allowing simultaneous transmissions without interference from other devices on the same switch. This increases overall network efficiency and throughput since multiple devices can communicate at the same time. By segmenting the network, a Layer 2 switch ensures that data traffic is isolated to specific segments rather than being broadcast across all devices, which would happen in a hub-based network. This isolation minimizes the chances of collisions and improves the overall performance perceived by the users due to greater bandwidth availability. While options such as increasing broadcast traffic or eliminating routing may seem relevant, they misalign with the core advantages provided by Layer 2 switching in terms of user experience and network performance. Simplification of network design is also an advantage of segmentation, but the primary and most direct benefit related to user experience is the enhancement of bandwidth through reduced collision domains.
