Which command would you use to obtain a summary of the current active processes?

The command used to obtain a summary of the current active processes is indeed "diagnose sys top-summary." This command provides a concise overview of all processes currently active on the system, allowing an administrator to quickly assess resource usage and identify potentially problematic processes.

This command displays information such as CPU usage, memory consumption, and other status indicators that can help diagnose system performance issues or confirm that processes are running as expected. The "top-summary" aspect specifically focuses on providing a snapshot of these metrics in a summarized format, contributing to efficient monitoring and troubleshooting.

Other potential commands serve different purposes or may offer more detailed views but do not provide the same summary format specifically tailored to process activity. For example, commands focused on querying or diagnosing other system metrics might not summarize active processes effectively.
