1100 Testing 2

Which of the following method is not typically used to keep a computer system cool?

• CPU fans

• Case fans

• Liquid cooling systems

• Heat sinks

• Keeping the case open

You bought a new computer with two case fans that constantly run a little loud. However, right out of the box, you notice the system is exhibiting intermittent problems. You go into the BIOS and observe the CPU temperature is 100 degrees Fahrenheit (38 degrees Celsius). Which of the following best describes the thought process you should employ in your troubleshooting efforts?

• Consider removing the heat sink from the CPU and properly reapplying the thermal paste.

• Consider whether the case fans are working properly, and if the system air flow is adequate.

• Consider using a can of compressed air to blow clean the inside of the case and components.

• Consider troubleshooting issues and possibilities that are not necessarily related to cooling.

Abdel, an electrician, does not know much about computers so he orders a custom computer with a 1000 W power supply. However, the maximum wattage the system needs is 500 W. Which of the following statements are true? Select two.

• Too much extra power will be drawn potentially creating an electrical hazard.

• The 1000 W power supply will last longer than, for example, a 750 W power supply.

• The power supply will run hotter than if using, for example, a 750 W power supply.

• The computer will run hotter than if using, for example, a 750 W power supply.

• The power supply will only deliver up to 500 W of power and operate very efficiently.

Dakota uses a power supply tester to examine the power supply on a friend's desktop computer that is exhibiting problems. The tester measured a 7 V reading from the +12 V output. Which devices are most likely to be affected by this deficiency? Select two.

• Graphics cards

• USB Ports

• SATA Drives

• CPU

• Keyboard and mouse

You are troubleshooting a serious issue for a friend because their computer does not boot up properly. What method should be employed to ensure the user's data is protected?

• Use a professional data recovery service to copy the data to another storage media.

• Use Windows Explorer to copy the data to another storage media on the local system.

• Connect the drive to another computer and copy the data to another storage media.

• Ask the user if they backed up the data. If they say yes, you can proceed with caution.

What is a reasonable best guess as a starting point when a user claims their Word documents are getting corrupt?

• The user is not saving the files properly.

• The application needs to be reinstalled.

• The application needs to be patched.

• The hard drive needs to be replaced.

What should you do if the local system has issues booting up and you need to back up the data?

• Use the local system to try to back up the data.

• Connect the drive to another computer, power on, and log in as Administrator.

• Assume the data has been safely backed up.

• Make sure the user can restore the data successfully.

Your laptop at home is exhibiting intermittent problems and you suspect it could be related to power. How can you verify the power adapter is supplying the proper voltage?

• Replacing the old power adapter with a new one is a reasonable way of verifying it is delivering the right amount of voltage and power.

• Verify the electrical outlet is delivering power then plug in the power adapter. Connect the 24-pin P1 connector into a power supply tester.

• Use a multimeter. Place the black probe of the multimeter in the center of the DC connector and the red probe on the outside cylinder.

• Use a multimeter. Place the red probe of the multimeter in the center of the DC connector and the black probe on the outside cylinder.

Li, a helpdesk technician, is troubleshooting a system. Based on experience, Li has narrowed down the problem and believes it is related to either the motherboard, processor, or RAM. Which symptoms would have allowed Li to narrow down the problem? Select three.

• The system reports less memory than is installed.

• An error message says there is no operating system.

• The system begins to boot but then powers down.

• An error message is displayed while booting.

• A loud whining noise as the system is booting.

You have an eight-year-old computer with all the original components still in place. The power supply fan seems to be going bad, so you start troubleshooting. You replace the power supply, but the fan continues to have the same problem. You then disconnect all the other components except the motherboard. Only under this condition does the fan work as expected. Which of the following is most likely to be true?

• The motherboard is faulty.

• The RAM is faulty.

• The hard drive is faulty.

• The CPU is faulty.
