Chapter 4 Exam Review: ITE Key Solutions
Dust - correct answer ✔✔Which negative environmental factor does cleaning the inside of a computer
reduce?
Fan - correct answer ✔✔Which component can be easily damaged by the direct spray of compressed air
when cleaning the inside the computer case?
the dust - correct answer ✔✔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 laptop container - correct answer ✔✔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 temperature - correct answer ✔✔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?
documenting the details and frequency of each maintenance task - correct answer ✔✔What is part of
creating a preventive maintenance plan?
Remove dust from intake fans. - correct answer ✔✔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?
