What are potential symptoms of a network bottleneck?

A network bottleneck occurs when the capacity of a network is limited, resulting in a slowdown of data transmission. The symptoms associated with a network bottleneck are particularly characterized by slow network performance and dropped connections. This happens because as more data is attempted to be transmitted through a network segment than it can handle, the excess data packets may take longer to process, leading to latency. This delay often causes timeouts, which can result in dropped connections.

On the other hand, increased bandwidth and faster speeds, high security and reliability, and improved user accessibility reflect conditions of an efficient network rather than symptoms of a bottleneck. These options represent the opposite of the issues caused by a bottleneck, which typically disrupts the overall performance and reliability of the network. Understanding these symptoms is crucial for network technicians to identify and address issues effectively.
