What is the primary advantage of a star topology in network design?

The primary advantage of a star topology in network design is that it allows for easy identification of damaged cables. In a star topology, all devices are individually connected to a central hub or switch. This configuration means that if a cable fails, it does not affect the entire network; only the device connected via that specific cable will experience issues. Consequently, network administrators can quickly isolate the problem to a particular segment or device, making troubleshooting more efficient.

Additionally, since all devices are routed through the central hub, it is straightforward to trace connections and identify which cable may be faulty or which device is not communicating properly. This visual clarity enhances network reliability and facilitates maintenance operations significantly. Other options, while beneficial in different contexts, do not reflect the primary advantage of this specific topology.
