What does POST stand for in the boot process of Cisco devices?

In the boot process of Cisco devices, POST stands for Power On Self Test. This is a diagnostic process that occurs when the device is powered on. During POST, the device runs a series of tests to check the hardware components, ensuring that everything is functioning correctly before the operating system is loaded. This includes checking the CPU, memory, and other essential components to confirm they are operational and free from faults.

If issues are detected during the POST, the device will typically provide an error message or indicators to help diagnose the problem. This fundamental step is critical because it ensures that all necessary components are in good working condition, preventing potential failures during normal operation. The other options do not accurately describe the standard terminology used in the networking domain for this specific process.
