Are collision domains a concern on a switched network?

• A. True
• B. False
• C. Only in specific scenarios
• D. Only in wireless connections

Answer: (B)

In a switched network, collision domains are not a concern due to the way switches operate. A switch creates a separate collision domain for each port, which means that each device connected to a switch port operates in its own domain, effectively isolating its traffic from others. This isolation allows devices to communicate simultaneously without the risk of frame collisions that are typical in shared media environments, such as those using hubs. When devices send data over a switch, the switch intelligently forwards the data to the appropriate destination based on MAC addresses. This process ensures that packets are delivered without interference from other devices on the network, alleviating the concerns around collisions. In contrast, in environments where multiple devices share the same medium without switches, such as with hubs or wireless connections, collisions can occur. This situation can lead to network inefficiencies and the need for protocols like CSMA/CD to manage traffic. Therefore, in a switched network, concerns regarding collision domains are effectively mitigated, making the correct answer that they are not a concern.
