Which command would you use to check the status of network connections and performance?

To check the status of network connections and performance, the appropriate command is designed to provide comprehensive information about the system's overall health, including network aspects. The command that is most relevant for this purpose is the one that reports on various aspects of the system, including connected interfaces, routes, and overall network connection status.

When you use this command, it typically returns a detailed view of the system's operational state, giving insight into network connectivity, performance metrics, and any potential issues affecting the network operations. This holistic view is crucial for network administrators to diagnose problems, monitor performance, and ensure the network is functioning optimally.

The other options do not specifically address the comprehensive connectivity and performance details to the extent needed. For instance, checking network status or monitoring network connections may be limited in scope, focusing only on specific aspects rather than providing an overview. Similarly, retrieving performance metrics may not encompass all the connectivity information, which can lead to an incomplete picture of the network's status. Thus, the command that gives a complete system overview, including network connections and performance indicators, is the most suitable choice.
