In a network with a broadcast domain, which device would be appropriate to segment traffic effectively?

To effectively segment traffic within a broadcast domain, using a switch is the ideal choice. A switch operates at the data link layer of the OSI model and is designed to intelligently forward data packets based on the MAC addresses of connected devices. This capability allows a switch to create separate collision domains for each connected device, which minimizes unnecessary traffic and reduces collisions.

When devices communicate through a switch, the switch maintains a MAC address table that enables it to direct traffic only to the intended recipient, rather than broadcasting the data to all connected devices. This process effectively reduces the size of the broadcast domain because broadcasts sent by one device will only reach the switch, not every device on the network, thereby isolating the segments of the network more effectively.

In contrast, other devices such as a hub, repeater, or bridge lack this level of intelligence. A hub simply broadcasts incoming data to all ports, leading to an increased number of collisions and traffic congestion. A repeater amplifies signals but does not segment traffic, and a bridge segments a network but does so less efficiently than a switch in terms of collision domain management and traffic filtering.

Therefore, a switch is the most effective device for managing and segmenting traffic within a broadcast domain, enhancing overall network performance and reducing
