Question 1

An employee frequently leaves their computer running overnight. Which BIOS setting should be adjusted to conserve energy during these idle hours?

Correct Answer: Wake-on-LAN

Wake-on-LAN allows a computer to be remotely powered on and can be used to schedule energy-saving features during idle hours. Other settings, such as boot order, virtualization support, integrated peripherals, legacy USB support, and TPM, do not directly affect energy conservation.

Question 2

A company wants to reduce their carbon footprint. Which power management setting should be configured to save energy when computers are idle for a short period?

Correct Answer: Sleep mode

Sleep mode is the best power management setting to save energy when computers are idle for a short period. In sleep mode, the computer enters a low-power state where the current state of the system is saved to RAM, allowing for quick resumption of work when the computer is woken up. This setting conserves energy while still allowing the user to quickly resume their work. Hibernate mode saves the system state to disk and powers down, which takes longer to resume and is better suited for longer periods of inactivity. Shutting down the computer completely would not be practical for short idle periods as it would require a full reboot to resume work. Disabling power management would not save any energy at all.

Question 3

After updating the software on a workstation, a technician notices that the system is generating excessive heat. What action should be performed to reduce the system's heat generation?

Correct Answer: Clean dust from the system and ensure proper cooling

Cleaning dust from the system and ensuring proper cooling is the best action to reduce the system's heat generation. Dust buildup can impede airflow and cause components to overheat. Ensuring proper cooling, such as checking fans and airflow, helps dissipate heat effectively. Increasing CPU voltage or GPU clock speed would generate more heat, while decreasing CPU core count would not address the root cause of excessive heat generation.
