Which statement correctly describes the role of Chassisd in Junos?

Chassisd plays a crucial role in managing the physical hardware of Juniper devices, particularly in relation to the device's power and cooling systems. This includes monitoring and controlling temperature levels, fan speeds, and power supply status. By ensuring that the hardware operates within safe thermal thresholds and receives adequate power, Chassisd helps maintain the stability and longevity of the device.

This operational aspect is essential as thermal management directly affects the performance and reliability of networking equipment. Proper cooling prevents overheating, which can lead to hardware failures and outages, while power management ensures that the device functions without interruption. By focusing on these critical hardware management tasks, Chassisd contributes to the overall health and efficiency of Junos devices.
