   All the desktop icons on a user's newly issued PC are very large. The user reports that the PC was working fine until a recent software patch was deployed. Which of the following would BEST resolve the issue?

   • ARolling back video card drivers
   • BRestoring the PC to factory settings
   • CRepairing the Windows profile
   • DReinstalling the Windows OS

   Show answer

   Answer: A

   Explanation

   The recent software patch may have changed the default icon size in Windows. Rolling back the video card drivers will restore the default icon size. Restoring the PC to factory settings or repairing the Windows profile are more drastic measures that should only be taken if rolling back the video card drivers does not resolve the issue. Reinstalling the Windows OS is the last resort and should only be done if all other options have failed.

   A computer on a corporate network has a malware infection. Which of the following would be the BEST method for returning the computer to service?

   • AScanning the system with a Linux live disc, flashing the BIOS, and then returning the computer to service
   • BFlashing the BIOS, reformatting the drive, and then reinstalling the OS
   • CDegaussing the hard drive, flashing the BIOS, and then reinstalling the OS
   • DReinstalling the OS, flashing the BIOS, and then scanning with on-premises antivirus

   Show answer

   Answer: B

   Explanation

   B. Flashing the BIOS, reformatting the drive, and then reinstalling the OS. This process will completely erase the hard drive, removing any traces of the malware infection, and then reinstall a clean version of the operating system. Flashing the BIOS can also help to ensure that any malware that may have infected the BIOS is removed. Option D, “Reinstalling the OS, flashing the BIOS, and then scanning with on-premises antivirus,” is not the best method for returning a malware-infected computer to service because it does not include reformatting the drive. Reformatting the drive is an important step in removing any traces of the malware infection. Simply reinstalling the OS without reformatting the drive may not completely remove the malware. Scanning with on-premises antivirus is also an important step, but it should be done in conjunction with reformatting the drive to ensure that the malware is completely removed.

All changes should undergo a risk analysis process to identify such risks and any controls or countermeasures that can be implemented. The goal of such countermeasures may be either to reduce the risk to a level the organization is comfortable with or to eliminate it entirely."
