   • fan
   • heat sink
   • power supply
   • CPU
   • cable connectors
     

     Explanation: When you clean the inside of the computer, hold the fan blades in place. This prevents over-spinning the rotor or moving the fan in the wrong direction.

3. 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 temperature
   • the humidity
   • the air flow
   • the dust
     

     Explanation: Most laptops are created to be tolerant of a wide range of humidity levels and room temperatures. Dust, however, can cause overheating and failures.

4. 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 room temperature
   • the humidity
   • the noise
   • the laptop container
     

     Explanation: The temperature and humidity levels are within normal expectations for laptops. Noise isn’t a factor. The wooden box environment would prevent proper air flow.

5. 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 temperature
   • the humidity
   • the rough terrain
   • the wind
     

     Explanation: 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.

    • documents that are created by the customer
      

      Explanation: Only customer created data is necessary for backup as a precaution to the troubleshooting process.

12. A customer reports that recently several files cannot be accessed. The service technician decides to check the hard disk status and the file system structure. The technician asks the customer if a backup has been performed on the disk and the customer replies that the backup was done a week ago to a different logical partition on the disk. What should the technician do before performing diagnostic procedures on the disk?

    • Run the CHKDSK utility.
    • Back up the user data to a removable drive.
    • Perform file restore from the existing backup copy at the logical partition.
    • Install a new hard disk as the primary disk, then make the current disk a slave.
      

      Explanation: Always perform a backup before beginning any troubleshooting. Even though the data was backed up to a different partition, the data is still on the same hard drive. If the drive crashes, the data might not be recoverable.

13. What is the next step after a possible solution is implemented during a troubleshooting process?

    • Test another possible solution.
    • Identify other possible causes for the problem.
    • Document the cause and the solution for the problem.

    • Download advanced antivirus software from another vendor.
    • Run a full virus scan on the computer.
    • Review the Event Viewer for the date and time that the last software update was performed.
      

      Explanation: After the repairs have been completed, continue the troubleshooting process by verifying full system functionality and implementing any needed preventive measures.

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

    • Document each test that was tried.
    • Ask the customer to open a new support request.
    • Redo each test to ensure the accuracy of the results.
    • Replace all hardware components with components that are known to work.
      

      Explanation: Before escalating a ticket, document each test that has been performed. Information about the tests is vital if the problem needs to be escalated to another technician.

16. Which step of the six-step troubleshooting process is where a technician would ask the computer user to print a document on a newly installed printer?

    • Test the theory to determine the cause.
    • Identify the problem.
    • Establish a theory of probable cause.
    • Document findings, actions, and outcomes.
    • Establish a plan of action to resolve the problem and implement the solution.
    • Verify full system functionality and, if applicable, implement preventive measures.
      

      Explanation: After the problem has been resolved, a technician should always verify full system functionality to ensure that the solution worked properly. This usually involves having the user test the original problem to ensure that it is fixed and that no new problems have been introduced.

17. After a technician tests a theory of probable causes, what two actions should the technician take if the testing did not identify an exact cause? (Choose two.)

    • Establish a new theory of probable causes.
    • Randomly replace components one at a time until the problem is solved.
    • Document each test tried that did not correct the problem.
    • Verify full system functionality.
    • Test all remaining possible causes starting with the most complex.
      

      Explanation: If the exact cause of the problem has not been determined after you have tested all your theories, establish a new theory of probable causes and test it.

18. What is the preferred method to remove a disc from an optical drive that fails to eject the disc?

    • Insert a pin into the small hole on the front of the drive.
    • Use a small screwdriver and pry the drive door open.
    • Remove the top of the drive enclosure.
    • Send the drive to an authorized repair depot.
      

      Explanation: If a computer will not eject the optical disc, to open the tray you can insert a pin in the small hole next to the eject button on the drive.

    • The PC would emit a series of beeps.
      

      Explanation: In the United States, the wall outlet electrical power is standardized at 120 volts AC.

21. During the troubleshooting of a PC that will not boot, it is suspected that the problem is with the RAM modules. The RAM modules are removed and put into another PC, which successfully powers on. The RAM modules are then put back into the original PC and it now successfully powers on as well. What was the most likely cause of the problem?

    • The RAM modules have bad blocks.
    • The RAM modules were not seated firmly.
    • The RAM modules did not match the PC specs.
    • The RAM modules were inserted backwards into the DIMM slots.
      

      Explanation: If RAM is not seated firmly in the motherboard DIMM slots, it will not function properly. RAM cannot be inserted backwards into a DIMM slot because both the RAM chip and the slot are keyed so they only fit one way.

22. After a new PCIe video card is added, the computer seems to boot successfully but it will not display any video. The computer was working properly before the new video card was installed. What is the most likely cause of the problem?

    • The monitor cable is faulty.
