How long is the power cycle during the IP reset procedures using the telnet command?

The correct answer is based on the standard procedures established for IP reset operations using the telnet command. During these reset procedures, the power cycle is typically specified to last for 4 seconds. This duration is crucial because it allows sufficient time for the device to fully reset and reinitialize its system processes, ensuring that any previous commands or states are completely cleared.

A shorter power cycle, like 2 seconds, may not provide enough time for the hardware to stabilize, potentially leading to incomplete resets or persistent errors. Conversely, longer cycles such as 10 or 20 seconds could be unnecessarily lengthy, delaying the re-establishment of network services without providing significant additional benefits. Maintaining the 4-second standard strike a balance between efficiency and effectiveness in the reset process, making it the recommended practice for users performing IP resets through telnet.
