The show system resource-utilization command is the designated utility within the ArubaOS-CX command-line interface for monitoring the switch's real-time performance. It provides an immediate snapshot of both CPU and memory usage. The output details CPU utilization percentages (broken down into user, system, and idle states) and memory statistics (including total, used, and free memory). This command is fundamental for network administrators to assess the operational health and current load on the switch hardware.

A. show cpu-memory: This is not a valid command in the ArubaOS-CX CLI. While descriptive, the correct syntax is different.

C. show log: This command displays the system's event log buffer, which records historical events, not real-time resource utilization statistics.

D. show clock: This command is used exclusively to display the current system date and time, and has no function related to resource monitoring.

"Displays the system resource utilization information. This command displays the CPU and memory utilization for the switch." An example output confirms it shows real-time CPU and memory data.

Page 2188: The show log command is described as displaying the contents of the event log.

Page 1988: The show clock command is described as displaying the current system clock time.

A search of the document confirms that show cpu-memory is not a listed command.
