Bridges are commonly needed in scenarios involving what specific connectivity challenge?

Bridges are specifically designed to address the issue of traffic management on a Local Area Network (LAN). They serve as devices that connect different segments of a network, allowing them to function as a single network while also reducing congestion. By segmenting traffic, bridges help isolate collisions and improve overall network performance. This means that when one segment of the network experiences a heavy load, the bridge can effectively manage data flow, ensuring that not all traffic has to go through a single channel.

The other connectivity challenges, such as high latency, limited bandwidth on WAN links, and improper IP address allocation, involve different technological solutions and do not directly pertain to the specific role of bridges in managing LAN traffic. High latency is often addressed by optimizing network paths or utilizing different types of connections. Limited bandwidth usually requires strategies like bandwidth management or increasing capacity, rather than using a bridge. Similarly, improper IP address allocation necessitates network planning and configuration, rather than the traffic management function that bridges provide.
