Which of the following is NOT a characteristic of network performance monitoring?

User monitoring is not typically considered a characteristic of network performance monitoring. The primary focus of network performance monitoring is on the health, status, and performance of network infrastructures, rather than the end-user interactions with applications.

High-quality process communications refer to the efficiency and reliability of data transmission across the network, which is essential for monitoring the network's performance. Dynamic topology understanding involves keeping track of the network's structure and how devices connect and communicate with each other, which is crucial for identifying potential bottlenecks and failures. Process-level capacity monitoring provides insights into how much of the network's resources (such as bandwidth) are being utilized, enabling better management of network capacity and performance.

In contrast, user monitoring usually deals with the performance of applications as experienced by the end-users, including metrics like response times and user satisfaction, which falls under application performance monitoring rather than network performance monitoring.
