What is one benefit of a switched LAN?

A key benefit of a switched LAN is its ability to limit the collision domain. In traditional shared media networks, such as those using hubs, all devices share the same collision domain, leading to potential collisions when multiple devices attempt to send data simultaneously.

With a switched LAN, each port on the switch represents its own individual collision domain. This means that devices connected to different ports can communicate with each other simultaneously without causing collisions, significantly improving network performance and efficiency. As the switch intelligently forwards packets only to the relevant destination port, it reduces unnecessary traffic and collisions, allowing for greater bandwidth availability for each device. This characteristic is essential in modern networking environments where performance and efficiency are critical.

While the other choices present characteristics related to LAN operations, they do not capture the significant advantage that limiting the collision domain offers in terms of enhanced data transmission reliability and network performance.
