Which of the following does NOT describe network performance management?

Updating software on devices is a configuration management or patch management activity, not a performance management function. Network performance management is concerned with collecting and presenting performance data, detecting anomalies, and alerting operations staff - it does not encompass making configuration or software changes to devices.

Near real-time graphing of performance metrics such as bandwidth utilization or latency is a core feature of network performance management tools.

Gaining visibility across multiple network devices simultaneously is a fundamental capability of performance management platforms.

Alerting operations staff in real time when a threshold is crossed or an anomaly is detected is a primary function of network performance management.

Viewing virtual server statistics such as connection rates and resource utilization is a standard network performance management capability, especially in software-defined or virtualized environments.
