11.9.6 Practice Questions Network Troubleshooting

Which of the following are critical times when memory problems manifest themselves? (Select two.) answer After cleaning the dust from inside your computer On the first boot of a new computer After you reconfigure the BIOS/UEFI After installing new drivers on your computer After you remove or install hardware

After you remove or install hardware On the first boot of a new computer

After installing two memory modules, you power on the system to check for errors. You find that the BIOS program recognizes only one of the memory modules. Which of the following is BEST to try first when troubleshooting this issue?

Change the memory timings in the BIOS to a slower (higher) setting. Reboot the computer and run memory diagnostic tests. Return both modules for a replacement. Correct Answer: Make sure that both modules are seated properly in their slots. Scan for new devices in Device Manager and enable any disabled memory modules.

As a computer technician, you are troubleshooting a client's computer that is experiencing intermittent crashes and sudden reboots. The client reports that these issues started happening after a recent memory upgrade. You have already confirmed that the new memory modules are compatible with the system and are properly installed. What would be the next BEST step to diagnose the issue?

Check the system for any software bugs. Check the system's power supply for any fluctuations. Install a new operating system on the computer. Run a memory diagnostic tool to check for any memory errors. Running a memory diagnostic tool to check for any memory errors is the correct answer. Running a memory diagnostic tool can help John identify if there are any issues with the new memory, such as errors that only occur under certain conditions (i.e., intermittent errors).

You are attempting to boot a new system. The boot fails, and the system sounds a beep code. Which of the following describes the MOST likely cause of this error? answer The new memory is not compatible and was not installed and configured properly. The POST failed to recognize all of the memory. Either no memory is installed or the memory was not detected. Either a card/memory module is not seated properly or the system includes unsupported memory.

Either no memory is installed or the memory was not detected.

Which type of software-generated problems can indicate that a software bug is causing a memory error? (Select three.) answerIncorrect answer: memory count Memory mismatch General-protection fault Correct Answer: Exception error Page fault Parity interrupt

Exception Error General-protection fault Page fault Memory mismatch display an error indicate that usually indicates discrepancies between new and old memory. Parity interrupt usually indicates a failing module or discrepancies between new and old memory. An incorrect memory count can happen with incompatible memory installation. Remember to avoid combining dual-bank memory with single-bank memory.

You have installed a new computer with a quad-core 64-bit processor, 6 GB of memory, and a PCIe video card with 512 MB of memory. After installing the operating system, you see less than 4 GB of memory showing as available in Windows. Which of the following actions would MOST likely correct this issue?

Flash the BIOS. Disable the AGP aperture in the BIOS. Install a 64-bit version of the operating system. Update the memory controller driver in Device Manager.

You are in the process of configuring a new computer. The motherboard has four memory slots and supports dual-channel memory. You install two memory modules. When you boot the computer, the BIOS recognizes both modules, but the memory is not configured to run in dual-channel mode. What should you do to resolve the issue?

Move the modules to the correct motherboard slots. Change the CAS latency to a higher setting. Replace the memory with dual-channel capable memory. Add continuity modules to unused memory slots.

After installing a new RAM module, you boot your 64-bit system, but the display remains blank. What is the MOST likely cause of this issue? You have installed a 32-bit memory module. The Registry is configured to write to faulty sections of RAM. You have installed a non-parity RAM on an ECC system. The POST failed to recognize the new memory.

You have installed a non-parity RAM on an ECC system. Non-parity (or non-ECC) memory is incompatible with an ECC system, which is the mostly likely cause of the blank screen.

Which of the following are the MOST likely signs that your computer might need more memory? (Select two.)

Your hard drive light on the system case is on for long periods of time. Your system boots, but the memory count is incorrect. You receive an exception error when running a software program. Your hard drive is constantly operating as you work.
