    • increased repair costs
    • increased number of regular updates
    • increased downtime
      Answers Explanation & Hints:

      Having a preventive maintenance plan in place can lead to improved reliability, performance, and efficiency in the IT infrastructure. If a preventive maintenance plan is not in place, it can often lead to issues that will cause infrastructure downtime and significant repair costs. A preventive maintenance plan helps ensure that these costly issues are handled before they become a problem.

  4. A user has opened a ticket that indicates that the computer clock keeps losing the correct time. What is the most likely cause of the problem?

    • The CMOS battery is loose or failing.
    • The operating system needs to be patched.
    • The CPU needs to be overclocked.
    • The motherboard clocking crystal is damaged.

      • Remove dust from components found inside the computer;
      • Clean mouse and keyboard;
      • Check for and secure any loose cables.
      Maintenance tasks like defragmenting a disk or scanning a hard drive for errors are part of a software maintenance routine.

  6. 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 wind
    • the humidity
    • the temperature
      Answers Explanation & Hints:

      Even though laptops are normally manufactured to operate within a wide range of temperatures, the lower temperature is below freezing and not an optimal environment.

  7. What is the most important reason for a company to ensure that computer preventive maintenance is done?

    • Preventive maintenance enables the IT manager to check on the location and state of the computer assets.
    • Preventive maintenance helps to protect the computer equipment against future problems.
    • Preventive maintenance provides an opportunity for junior technicians to obtain more experience in a non-threatening or problem environment.
    • Preventive maintenance allows the IT department to regularly monitor the contents of user hard drives to ensure computer use policies are being followed.
      Answers Explanation & Hints:

      Preventive maintenance includes tasks such as cleaning the device, which can prolong the life of the device.

  8. After a problem is identified, what is the next step for the troubleshooter?

      Step 4. Establish a plan of action to resolve the problem and implement the solution.
      Step 5. Verify full system functionality and, if applicable, implement preventive measures.
      Step 6. Document findings, actions, and outcomes.

  9. What task should be completed before escalating a problem to a higher-level technician?

    • Replace all hardware components with components that are known to work.
    • Redo each test to ensure the accuracy of the results.
