    Rate this question:

  • 12. 

    A computer with the Windows 7 operating system fails to boot when the system is powered on. The technician suspects that the operating system has been attacked by a virus that rendered the system inoperable. What measure could be taken to restore system functionality?

    • A.

      Run chkdsk on the affected drive to restore system files to their post-installation state.

    • B.

      Use an incremental backup to restore the system.

    • C.

      Use a system image that was created prior to the failure to restore the system.

    • D.

      Use a differential backup to restore the system.

    Correct Answer
    C. Use a system image that was created prior to the failure to restore the system.
    Explanation
    To restore system functionality after a suspected virus attack, using a system image that was created prior to the failure would be the most effective measure. A system image is a complete snapshot of the operating system, including all files, settings, and installed programs. By restoring the system using a previous system image, it would revert the operating system back to a known good state, eliminating any potential virus infection and allowing the computer to boot successfully. Running chkdsk may help fix file system errors, but it would not address the virus issue. Incremental and differential backups are not comprehensive enough to restore the entire system.

    Rate this question:

  • 13. 

    After upgrading a computer to Windows 7, a user notices that the UAC (User Account Control) panel appears more frequently. How can the user reduce the frequency with which the UAC appears?

    • B.

      In the Performance Options dialog box of the Performance Information and Tools control panel, choose Adjust for Best Performance.

    • C.

      Lower the UAC setting in the Change User Account Control settings dialog box of the User Accounts control panel.

    • D.

      Reinstall all user programs in Compatibility Mode.

    Correct Answer
    C. Lower the UAC setting in the Change User Account Control settings dialog box of the User Accounts control panel.
    Explanation
    Lowering the UAC setting in the Change User Account Control settings dialog box of the User Accounts control panel will reduce the frequency with which the UAC appears. This setting determines the level of notification and permission requests that the UAC panel displays. By lowering the setting, the user will receive fewer prompts, allowing for a smoother and less interrupted user experience.

    A user notices that a PC is running slowly and exhibits a delayed response to keyboard commands. What is a probable cause of this symptom?

    • A.

      The video card does not support the resolution that is being used.

    • B.

      A recently installed device driver is incompatible with the boot controller.

    • C.

      A process is using most of the CPU resources.

    • D.

      One or more program files have been deleted.

    Correct Answer
    C. A process is using most of the CPU resources.
    Explanation
    A probable cause of a PC running slowly and exhibiting a delayed response to keyboard commands is that a process is using most of the CPU resources. When a process consumes a significant amount of CPU power, it can cause other tasks to slow down and result in delayed responses. This can happen due to a poorly optimized or resource-intensive program running in the background. By identifying and terminating the process that is hogging the CPU, the PC's performance can be improved.

    Rate this question:

    What would be the result of having a corrupt Master Boot Record?

    • A.

      The printer will function incorrectly.

    • B.

      The operating system will fail to start.

    • C.

      A new application will fail to install.

    • D.

      The keyboard will be unresponsive to the user.

    Correct Answer
    B. The operating system will fail to start.
    Explanation
    A corrupt Master Boot Record (MBR) can prevent the operating system from starting. The MBR is a small section of the hard drive that contains essential information for the computer to boot up. If it becomes corrupt, the computer may not be able to locate the operating system files and therefore fail to start. This can result in a black screen, error messages, or an endless boot loop. Other components like the printer, application installation, or keyboard functionality are not directly affected by a corrupt MBR.
