Which negative environmental factor does cleaning the inside of a computer reduce?

• Dust

• EMI

• ESD

• RUST

Which component can be easily damaged by the direct spray of compressed air when cleaning the inside of the computer case?

• Power Supply

• Fan

• Cable Connectors

• Heat Sink

On the production floor, a furniture plant has laptops for process monitoring and reporting. The production floor environment is around 80 degrees Fahrenheit (27 degrees Celsius). The humidity level is fairly high around 70 percent. Fans are mounted in the ceiling for air circulation. Wood dust is prevalent. Which condition is most likely to adversely affect a laptop that is used in this environment?

• The humidity

• The Dust

• The air flow

• The tempurature

A vegetable canning plant uses laptops for monitoring of assembly lines. The production environment has an ambient temperature around 75 degrees Fahrenheit (24 degrees Celsius). The humidity level is around 30 percent. Noise levels are high due to the canning machinery. The laptops are in a wooden box that tightly surrounds the laptop on three sides. Which factor is most likely to adversely affect a laptop that is used in this environment?

• The noise

• The laptop Container

• The humidity

• The room Temperature

A scientific expedition team is using laptops for their work. The temperatures where the scientists are working range from -13 degrees Fahrenheit (-25 degree Celsius) to 80 degrees Fahrenheit (27 degrees Celsius). The humidity level is around 40 percent. Noise levels are low, but the terrain is rough and winds can reach 45 miles per hour (72 kilometers per hour). When needed, the scientists stop walking and enter the data using the laptop. Which condition is most likely to adversely affect a laptop that is used in this environment?

• The rough terrain

• The Temperature

• The Wind

• The Humidity

What is part of creating a preventive maintenance plan?

• documenting the details and frequency of each maintenance task

• Performing Hardware Upgrades

• Discarding all replaced parts

• performing forensic audit of security breaches

A technician is performing hardware maintenance of PCs at a construction site. What task should the technician perform as part of a preventive maintenance plan?

• Remove dust from Intake fans

• Develop and install forensic tracking software

• Back up the data, reformat the hard drive, and reinstall the data.

• Perform an audit of all software installed

Which task should be part of a hardware maintenance routine?

• Review security updates

• Adjust the monitor for resolution

• update virus definition files

• Remove hard drive dust

• check for and secure any loose cables

During the process of testing a theory of several probable causes to a problem, which should be tested first?

• those chosen by random selection

• the most complex and difficult to diagnose

• those the customer believes to be most important

• the easiest and most obvious

Which two items could be used to help establish a plan of action when resolving a computer problem? (Choose two.)

• The computer manuel

• a multimeter

• the computer repair manuel

• The computer repair log history

• BIOS diagnostic
