Which type of network topology allows troubleshooting a problem or switching around the problem to be accomplished easily from the central hub?

Star topology is the correct answer because it features a central hub that connects all the individual nodes (devices) in the network. When a problem arises, such as a device failure or a connection issue, it is often easy to isolate the problem by checking the central hub or the connections to individual nodes. The hub acts as a point of control, facilitating quick identification and resolution of issues without disrupting the entire network.

In contrast, line topology, which connects nodes in a single linear sequence, may make troubleshooting more challenging since issues can affect all the devices connected along the line. Mesh topology offers redundancy and multiple paths for data to travel, but requires more complex configurations to identify specific failure points, making troubleshooting less straightforward. Hybrid topology, while combining elements of various topologies, inherits complexities that can make pinpointing issues more difficult compared to the streamlined approach of a star topology.
