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

The star topology is particularly advantageous for troubleshooting because all devices are connected to a central hub or switch. This central point acts as a relay for data traffic, which simplifies the process of diagnosing network issues. If a device experiences problems or if a segment of the network goes down, network administrators can easily identify the specific device or link that is malfunctioning by checking the central hub. Additionally, since each device has its own dedicated connection to the hub, isolating and addressing issues is straightforward; the failure of one connection does not impact the others.

In this topology, if a cable or device fails, it can be quickly replaced or bypassed without disrupting the entire network. This ability to segment and manage issues directly from the central hub makes it significantly easier to maintain operational efficiency and minimize downtime compared to other topologies, such as bus or mesh, where the interconnected nature might complicate problem-solving efforts.
