What adjustment can typically help enhance throughput on a congested network segment?

Increasing the bandwidth of the network connection is a common approach to enhance throughput on a congested network segment. This adjustment allows more data to be transmitted simultaneously, effectively alleviating congestion and reducing bottlenecks. When bandwidth is increased, the capacity for data transfer rises, making it easier for multiple devices to communicate without interference or slowdowns.

Other options might address different aspects of network management but may not directly influence throughput in a congested scenario. For example, lowering the number of allowed connections could reduce the overall load on the network, but it might also limit necessary connections for users or services, thereby not optimizing throughput effectively. Deactivating unused ports on the switch might enhance security and reduce potential influences from unused paths, yet it does not inherently increase the data capacity of the active connections. Changing the MTU (Maximum Transmission Unit) setting can optimize the process of packet transmission but is more about efficiency than outright throughput increase. In contrast, enhancing the network bandwidth directly expands the capacity for data flow and significantly improves overall network performance in congested situations.
