    What is the next step to take when you are updating a malfunctioning PCI card with a driver that you downloaded from the manufacturers web site and the card still does not work.?

    • The latency settings in the BIOS should be changed

    • Download an alternative driver from a different manufacturer

    • An AGP card should be installed

    • The PCI card should be replaced

    Correct Answer
    A. The PCI card should be replaced
    Explanation
    If updating the driver from the manufacturer's website did not resolve the issue and the PCI card still does not work, the next logical step would be to replace the PCI card. This is because the malfunctioning card may have a hardware issue that cannot be fixed by simply updating the driver. By replacing the card, it allows for a fresh start and the possibility of resolving the problem.

    Why would a computer continuosly restart without reaching the windows desktop?

    • There are some critical system files missing from the computer

    • The hard drive is full and will not allow windows to create a swap file

    • The Automatic restart on system failure option is enabled.

    • There is not enough RAM.

    Correct Answer
    A. The Automatic restart on system failure option is enabled.
    Explanation
    The computer continuously restarts without reaching the Windows desktop because the Automatic restart on system failure option is enabled. This means that whenever the system encounters a critical error, instead of displaying an error message or allowing the user to troubleshoot, it automatically restarts. This option is enabled by default in some operating systems and can be disabled to allow for better troubleshooting and error resolution.

    Why would a computer run slowly? (Choose 3)

    • Not enought RAM

    • Too many USB devices attached

    • Spyware and viruses

    • Excessive Virtual Memory

    • Running obsolete services.

    Correct Answer(s)
    A. Not enought RAM
    A. Spyware and viruses
    A. Running obsolete services.
    Explanation
    A computer can run slowly due to several reasons. One possible reason is not having enough RAM. RAM is the temporary storage space that a computer uses to perform tasks, and if there is not enough RAM available, the computer may struggle to run programs efficiently. Another reason could be the presence of spyware and viruses. These malicious software can consume system resources and slow down the computer's performance. Additionally, running obsolete services, which are outdated and unnecessary background processes, can also contribute to a slow computer as they consume valuable system resources.

    Your WinXp operating system became unstable after you installed a device driver and did not stabilize after you rebooted the computer with the Last Know Good Configuration. What is the reason for the computer behaving in this manner?

    • The Last Known good configuration boot will only work for hardware changes and not software changes that have been made.

    • The system restore application should have been used to save the systems registry prior to the installation of the device driver.

    • The last know good configuration was unable to find a valid restore point because the system restore was not run prior to the installation of the device driver.

    • The system registry is overwritten after every successful login and the settings on the initial install were thus overwritten after the first reboot and login.

    Correct Answer
    A. The system registry is overwritten after every successful login and the settings on the initial install were thus overwritten after the first reboot and login.
    Explanation
    The reason for the computer behaving in this manner is that the system registry is overwritten after every successful login. Therefore, the settings on the initial installation were overwritten after the first reboot and login, causing the operating system to remain unstable even after using the Last Known Good Configuration.

    As soon as you log in to your desktop the following box pops up saying   : Services.exe bad windows image file C:\windows\system32\mmcyptojqly.dll.  You suspect a rootkit infection so you restart and try to enter safe mode, however safe mode will not load, What will you do to fix the problem without formatting the computer? (choose 2)

    • Run recovery console and disable all but critical system services then load safe-mode

    • Attempt to remove rootkit thru advanced software such as GMER, ICESWORD, or rootkit unhooker.

    • Run a repair on your operating system

    Correct Answer(s)
    A. Run recovery console and disable all but critical system services then load safe-mode
    A. Run a repair on your operating system
    Explanation
    Your services process was hijacked by a piece of malware which has now pointed the program to that dll instead of the normal file. Safe mode is not working because the Rootkit is running its own service programmed to run in safe-mode which is preventing the complete start-up of safe-mode. Using the recovery console you can prevent any non-critical processes from loading and then attempt to load safe-mode. If that does not change anything, you can use your Windows CD to run a repair install on the operating system.

    A Network Admin at bobs company has several workstations with 802.11g network adapters. Each day at around lunchtime wireless users complain of lack of connectivity. What can you do solve this problem?

    • Replace the WAP with a 802.11 WAP

    • Reduce the Radio Frequency around the WAP

    • Configure the wireless workstations and the WAP to operate in ad-hoc mode

    • Connect the WAP directly to the network.

    Correct Answer
    A. Reduce the Radio Frequency around the WAP
    Explanation
    To solve the problem of lack of connectivity during lunchtime, reducing the radio frequency around the wireless access point (WAP) would be an effective solution. By reducing the radio frequency, interference from other devices or networks operating on the same frequency can be minimized, improving the overall connectivity for the wireless users. This can be achieved by adjusting the channel settings on the WAP or by using tools to identify and avoid congested frequency bands.
