Question 2

A company's IT policy requires that all disposed hard drives be physically destroyed to prevent data breaches. Which method has the least environmental impact while ensuring data destruction?

Accepted Answer

Shred the hard drive using an industrial shredder and then recycle the metal fragments.. Option C is correct because industrial shredding physically destroys the platters into small fragments, making data recovery impossible, and the resulting metal fragments can be recycled, minimizing environmental impact. Unlike degaussing or drilling, shredding ensures complete destruction without leaving large e-waste components, and the recycling of ferrous and non-ferrous metals reduces raw material extraction.

Answer

Use a degausser to erase the drive and then recycle it.

Answer

Drill holes through the platters and then dispose of the drive in e-waste.

Answer

Overwrite the drive with zeros multiple times and then donate it.

Question 3

During a printer toner replacement, a technician accidentally spills toner powder on the carpet. What is the proper cleanup procedure?

Accepted Answer

Blot the toner with a cold, damp cloth and then use a HEPA-filter vacuum.. Option C is correct because toner powder is extremely fine and can become airborne if mishandled. Blotting with a cold, damp cloth prevents the toner from spreading, and using a HEPA-filter vacuum ensures that microscopic toner particles are trapped without being exhausted back into the environment. Standard vacuum cleaners lack HEPA filtration and can release toner dust into the air, causing respiratory hazards.

Answer

Use a vacuum cleaner with a standard bag to suck up the toner.

Answer

Wipe the toner with a damp cloth using hot water.

Answer

Sweep the toner into a dustpan and dispose of it in the trash.

Question 8

A technician is configuring a new workstation for a customer who is concerned about energy consumption. Which setting should the technician enable to reduce power usage when the computer is idle?

Accepted Answer

Enable sleep mode after 15 minutes of inactivity.. Option C is correct because enabling sleep mode after 15 minutes of inactivity places the computer into a low-power state (S3 sleep, Suspend-to-RAM) where the CPU is powered down but RAM retains data, allowing a quick wake-up. This directly reduces energy consumption during idle periods more effectively than simply turning off the display, as it cuts power to the processor, drives, and most peripherals.

Answer

Disable the screensaver and set the display to turn off after 30 minutes.

Answer

Enable hibernation mode after 1 hour of inactivity.

Answer

Set the power plan to 'High performance' to reduce power draw.

Question 9
