Which type of network topology allows troubleshooting to be accomplished easily from the central hub?

The star network topology is distinguished by its arrangement in which all nodes (like computers and devices) are connected to a central hub or switch. This centralized structure greatly simplifies troubleshooting because, when a connection issue arises, you can easily isolate it by checking the central hub and the connections leading to the particular node experiencing problems.

If a node fails or there is an issue with a connection, it's straightforward to identify that specific branch leading to that node without needing to disrupt the entire network. Moreover, since all data traffic passes through the central hub, it becomes a focal point for monitoring and diagnosing problems, allowing for efficient detection and resolution.

In contrast, other topologies are less conducive to straightforward troubleshooting. For instance, in a bus topology, all devices share a single communication line, making it challenging to pinpoint faults without disconnecting the entire network. A mesh topology features multiple interconnections, providing redundancy but complicating the troubleshooting process due to the sheer number of possible connections. Meanwhile, a hybrid topology, which combines elements from various topologies, may also obscure the source of issues without a clear central point like the star topology offers.

Thus, the star topology’s centralized arrangement is why it is particularly effective for easy troubleshooting.
