    A user reports that after installing a PCIe video card into a system, the onboard video no longer displays. Which of the following is MOST likely the cause?

    • The drivers for the onboard video card have been overwritten by the PCIe video card drivers.

    • The PCIe video card is defective and is conflicting with the onboard video.

    • The BIOS detected the PCIe video card and disabled the onboard video.

    • The processor has overheated and is causing the video to not display.

    Correct Answer
    A. The BIOS detected the PCIe video card and disabled the onboard video.
    Explanation
    The most likely cause is that the BIOS detected the PCIe video card and disabled the onboard video. This is a common behavior for BIOS when a dedicated video card is installed, as it prioritizes the dedicated card over the onboard one. The drivers for the onboard video card being overwritten or the PCIe video card being defective and conflicting with the onboard video are less likely causes. The processor overheating would not directly affect the display of video.

    A technician is replacing a motherboard in a laptop. After completing the install, the laptop shuts down after a few seconds of being on. Which of the following is the causing the laptop to shutdown?

    • Keyboard is not plugged in.

    • CPU is not locked into the socket.

    • LCD is not plugged in.

    • RAM is faulty.

    Correct Answer
    A. CPU is not locked into the socket.
    Explanation
    If the CPU is not locked into the socket properly, it can cause the laptop to shut down after a few seconds of being on. This is because a loose or improperly installed CPU can result in poor contact between the CPU and the motherboard, leading to overheating. When the CPU overheats, the laptop's built-in thermal protection mechanism kicks in and shuts down the system to prevent damage.

    Which of the following is fault tolerant and allows for disk mirroring?

    • RAID 0

    • RAID 1

    • RAID 3

    • RAID 5

    Correct Answer
    A. RAID 1
    Explanation
    RAID 1 is fault tolerant and allows for disk mirroring. In RAID 1, data is written simultaneously to two or more disks, creating an exact copy or mirror of the data. This redundancy provides fault tolerance as if one disk fails, the data can still be accessed from the mirrored disk. RAID 1 offers high availability and data protection, making it suitable for applications that require data reliability and quick data recovery in case of disk failure.

    Which of the following is a method used in the removal of a boot sector virus?

    • Performing a standard format of the hard drive partitions

    • Booting the computer with peripheral devices disconnected

    • Scanning all CD-R and CD-RW media prior to initial use

    • Booting from the floppy disk or CD-ROM prior to scanning

    Correct Answer
    A. Booting from the floppy disk or CD-ROM prior to scanning
    Explanation
    Booting from the floppy disk or CD-ROM prior to scanning is a method used in the removal of a boot sector virus. This is because booting from a different source allows the computer to bypass the infected boot sector and load a clean operating system. By doing this, the virus is unable to activate and can be effectively detected and removed by scanning the system.

    • Blow compressed air on the print cartridges.

    • Run the printers cleaning routine.

    • Reseat the print cartridges.

    • Use a lint-free cloth to clean the print heads.

    Correct Answer
    A. Run the printers cleaning routine.
    Explanation
    Running the printer's cleaning routine would be the most appropriate solution for the issue of faded and smeared pages. This routine is specifically designed to clean the print heads and remove any clogs or debris that may be causing the printing issues. By running the cleaning routine, the printer will be able to clear any blockages and ensure that the ink is properly distributed, resulting in better print quality.

    Which of the following is a difference between a worm and spyware?

    • A worm replicates itself before infecting other systems.

    • Spyware replicates multiple times on one system before infecting another system.

    • A worm attacks one platform, where spyware attacks across platforms.

    • Spyware resides primarily in the boot sector, where a worm resides primarily in the registry.

    Correct Answer
    A. A worm replicates itself before infecting other systems.
    Explanation
    A worm is a type of malware that is capable of replicating itself and spreading to other systems without the need for any user interaction. This means that once a worm infects a system, it can independently create copies of itself and infect other vulnerable systems on a network. On the other hand, spyware is a type of malware that is designed to collect information from a user's computer without their knowledge or consent. While spyware can replicate itself multiple times on one system, it does not have the ability to independently infect other systems like a worm does.

    A user is attempting to access files shared on a remote computer. The file share permissions allow the user to have full control; however, the NTFS permissions allow the user to have read access. Which of the following is the users resulting access level for the remotely shared directory?

    • Modify

    • Full control

    • Write

    • Read

    Correct Answer
    A. Read
    Explanation
    The user's resulting access level for the remotely shared directory is "Read". This is because even though the file share permissions allow the user to have full control, the NTFS permissions only allow the user to have read access. NTFS permissions take precedence over file share permissions, so the user's access level is limited to read-only.

    A technician is upgrading memory in a desktop PC. The user purchased two 2GB DIMMS from the PC manufacturer. The PC powers on and POST shows 2GB of RAM. Which of the following is the FIRST action to perform?

    • Update the manufacturers chipset drivers.

    • Replace the two 2GB DIMMs with four 1GB DIMMs.

    • Update the PC BIOS and verify all memory is seen in POST.

    • Replace both of the 2GB DIMMs memory with new memory.

    Correct Answer
    A. Update the PC BIOS and verify all memory is seen in POST.
    Explanation
    The correct answer is to update the PC BIOS and verify all memory is seen in POST. This is because when upgrading memory in a desktop PC, it is important to ensure that the BIOS recognizes and detects the new memory modules. By updating the PC BIOS, any compatibility issues or limitations with the new memory can be addressed, and verifying that all memory is seen in POST confirms that the upgrade was successful. The other options, such as updating chipset drivers or replacing the DIMMs with different ones, are not necessary or relevant in this situation.
