In which topology would a break in the main route cause all network connectivity to be lost?

This question tests how the shared medium in a network topology affects failure impact. In a bus topology, all devices connect to a single main cable, the backbone. A break in that backbone cuts the path for every device, and there’s no alternate route for signals to reach any node, so all network communications are lost. Other topologies don’t behave this way: a ring can still lose connectivity if the loop is broken on one side, though some implementations can bypass the issue; a mesh provides multiple paths so a single break often doesn’t take down the whole network; a star keeps each device connected through a central hub, so a break in a single device-to-hub link tends to isolate that one device rather than the entire network.
