What percentage of connection attempts typically exceed the 2-second goal?

The correct choice, 25%, represents a common threshold in network performance metrics, where exceeding a 2-second connection time is considered a significant lag affecting user experience. In many scenarios, network managers and service providers aim to keep latency low to enhance responsiveness.

Research and performance benchmarks suggest that a small percentage of connection attempts are usually above the optimal threshold; thus, 25% serves as a realistic benchmark in identifying underperforming connections. By recognizing this statistic, network managers can focus on optimizing latency for those connection attempts that consistently fall outside the 2-second goal, thereby improving overall network performance and customer satisfaction.

In contrast, the percentages represented by the other options do not align as closely with the typical performance expectations seen in practical scenarios. Lower percentages might underrepresent the reality of network performance issues that can arise in various conditions.
