TestOut Flashcards - 13.7 System Errors
You have booted your Windows 7 workstation Into Safe Mode and enabled Boot Logging. To which log file is the boot logging Information now being written? A. Ntbtlog.txt B. Bootlog.txt C. Myboot.txt D. Boot.log
A. Ntbtlog.txt Explanation: When you choose to Enable Boot Logging, entries are written to the Ntbtlog.txt file. This file is created in the %WinDir% folder.
Christian has booted his Windows 7 workstation in Safe Mode and enabled Boot Logging. Which file would he examine to see a list of drivers loaded during the startup process? A. Boot.log B. Boot.ini C. Ntbtlog.txt D. Bootlog.txt
C. Ntbtlog.txt Explanation: When you choose to Enable Boot Logging, entries are written to the Ntbtlog.txt file. This file is created in the %WinDir% folder.
You need to boot a Windows 7 system into Safe Mode. Which key should you press during the system boot to access the Advanced Boot Options menu? A. F5 B. ALT C. F9 D. F8
D. F8 Explanation: Pressing the F8 button during the system boot brings up the Advanced Boot Options menu.
Marcus was attempting to tweak his workstations operating system when he inadvertently corrupted his system boot files. It will now no longer boot to a logon prompt. After pressing F8, which option should he choose? A. Debugging Mode B. Safe Mode with Command Prompt C. Last Known Good Configuration D. Repair Your Computer E. Boot Normally
D. Repair Your Computer Explanation: He should select Repair Your Computer. This will allow him to run a Startup Repair, which will probably be able to fix his startup files. Selecting Last Known Good Configuration will not be able to restore problems with his boot tiles. Boot Normally will attempt to boot as now configured. Debugging Mode runs the Kernel Debugger.
A user in the research department, reports that he is getting STOP errors on his Windows system during startup. You ask him if anything has changed recently on the computer. He explains that he ran the installation program for his PDA just before receiving the first STOP error. He immediately rebooted and has not been able to use Windows 7 since then due to STOP errors during the boot process. You need to fix his computer. What should you do? A. Perform a parallel installation of Windows 7. B. Re-install Windows 7 from the Installation DVD. C. Boot the system using a Windows 7 installation DVD and select the Startup Repair option. D. Reboot the system and select the Enable Boot Logging option to determine which driver is loading just before the STOP error occurs. E. Reboot the system. Select Last Known Good Configuration from the Advanced Startup options.
E. Reboot the system. Select Last Known Good Configuration from the Advanced Startup options. Explanation: Because a successful logon has not occurred since the STOP errors began, you can use the computers Last Known Good Configuration option. The new driver that is causing the boot problem will no longer be used. Because the boot process has progressed to the point that a STOP error is generated, you do not need to fix the boot sector or master boot record. Reloading the system or performing a parallel installation will likely correct the problem, but this is unnecessary. A parallel Installation would require another partition. The Enable Boot Logging option will generate a log of the driver loading process, but you already have a good idea of which driver is causing the problem and this is not a complete solution.
The video driver on your Windows 7 computer is preventing the system from starting up successfully. You have already downloaded an updated driver and copied it to the computer's hard drive. Which mode should you select from the Windows Advanced Boot Options menu that would most likely allow you to start the computer to continue fixing the problem? A. Enable VGA Mode B. Safe Mode C. Enable Boot Logging D. Safe Mode with Networking
A. Enable VGA Mode Explanation: Similar to Safe Mode, VGA mode loads a generic VGA driver instead of a third-party display driver that may be preventing Windows from starting correctly. This mode is very useful when you have installed a video board that isn't working. If your display becomes unreadable, use VGA mode to boot to a readable monitor and remove or reconfigure the driver or software that is causing the problem. Safe Mode loads a limited set of drivers, but does not load the generic video driver. If the video driver is the problem, VGA mode would likely be the better solution. Boot logging writes details about drivers that are loaded during the startup process.
You have a Windows XP Professional workstation that does not currently have the Recovery Console installed. Which command should you use to install the Recovery Console? A. WIN NT32 /CMDCONS B. SETUP CONSOLE C. SETUP /CONSOLE D. WINNT32 CONSOLE
A. WIN NT32 /CMDCONS Explanation: The /CMDCONS switch for WINNT32 is used to Install the Recovery Console. Installing the Recovery Console adds an option to the Startup menu.
Under which circumstances would using the Last Known Good option be most likely to correct the problem? A. If you made a system change and rebooted successfully once, but have been unable to reboot since. B. If you made a system change and then the startup fails before the logon screen. C. If you made a system change and the system continually crashes immediately after logon. D. If you have random lockups that happen when running specific applications.
B. If you made a system change and then the startup fails before the logon screen. Explanation: The best use of Last Known Good would be if you have made a change and then are not able to reboot and log on again. The Last Known Good option copies the system settings that existed at the last time of a successful logon. Last Known Good will not undo changes if you have been able to log on since the change has made. Any conditions that occur after logon will not be corrected.
You turn on your desktop computer. You can hear the fans start up, but the monitor remains blank. You wait a while, but it doesn't appear that anything else is happening. The hard drive activity light doesn't show activity, and you never hear the sound that plays when Windows loads up. Which of the following are the most likely cause of the problem? (Select three.) A. Mouse B. Processor C. Network card D. Memory E. Keyboard F. Hard disk G. Video card
B. Processor, D. Memory, & G. Video card Explanation: When a computer first boots, it checks the processor, memory, and video card. If any of these three components are faulty, the boot process will stop. Depending on the problem, you might see nothing displayed on the screen. If the hard disk is bad, the system will boot past the BIOS, but be unable to locate the operating system files. You will see a message displayed on the screen indicating this and other problems (such as a bad keyboard). The startup sequence typically does not diagnose the mouse.
Rodney, a user in the research department, reports that he is getting STOP errors while using his Windows XP computer. You ask Rodney if anything has changed recently on the computer. Rodney explains that he ran the installation program for his PDA and everything worked fine until he tried to hot sync. Now any time he hot syncs, he has to reboot the computer. You need to fix Rodney's computer and prevent Rodney from using the PDA until you can install an updated driver. What should you do? A. Reboot the system and select Safe Mode. Edit the properties of the PDAs driver in Device Manager and select Roll Back Driver. B. Reboot the system and select Safe Mode. Disable the PDA's driver in Device Manager. C. Boot the system using a Windows XP Professional CD-ROM, select the Recovery Console option, and then use the Fixboot and Fixmbr utilities. D. Re-Install Windows XP Professional from the CD-ROM. E. Reboot the system and select the Last Known Good Configuration from the Advanced Startup Options.
B. Reboot the system and select Safe Mode. Disable the PDA's driver in Device Manager. Explanation: You should disable the driver. Although you might be able to disable the driver without booting in Safe mode, booting in Safe mode is a good way to prevent drivers that could interfere with your task from being loaded. Because the system can successfully boot and the error occurs after logon, the Last Known Good Configuration option will still load the drivers. Rolling back the driver will not help because the driver was not updated, because the boot process is functioning, there is no indication that the boot sector or master boot record needs fixing using the Recovery Console. Reloading the system or performing a parallel installation will likely correct the problem, but this is unnecessary. A parallel installation would require another partition.
You have a Windows 7 computer that was recently upgraded from Windows XP. An installed application worked fine in Windows XP, but now does not run in Windows 7. You have checked the application vendor's web site but there is no update available. What should you try to run the application? (Select two options.) A. Make all users who need to run the application members of the local Administrators group. B. Run the application in compatibility mode. C. Run the application in its own memory space. D. Run the application in XP Mode.
B. Run the application in compatibility mode. & D. Run the application in XP Mode. Explanation: You can try two options: • Use the compatibility mode in Windows to run older applications as if they were running under a different operating system version. Older applications are often written to require full system access which is not allowed on Windows Vista because of UAC. Compatibility mode creates a shim or a layer that makes the application think it has access to the system that is typically denied in Windows 7. • Run the application in XP Mode. Windows XP Mode (XPM) is a virtual machine package for Windows Virtual PC that provides a pre-installed, licensed copy of Windows XP Professional that you can use to run XP applications. Granting users administrative privileges gives them rights to the entire system and not just to the single application. On Windows 7, most applications already run in a separate memory space.
A malfunctioning video driver is preventing your Windows system from starting successfully. Which startup option should you choose so you can copy an updated driver from the help desk support server? A. Directory Services Restore Mode B. Safe Mode with Networking C. Enable Boot Logging D. Safe Mode
B. Safe Mode with Networking Explanation: Safe Mode with Networking is required because the driver files must be copied from another server. Safe Mode by itself does not configure network connections. Directory Services Restore only applies to Domain Controllers. Boot Logging can be used to collect data about the boot process, but in this case, the video driver has already been identified as the cause of the problem.
How can you keep a Windows 7 system from restarting after a critical system error occurs? A. Use the Last Known Good configuration option on the Advanced Boot Menu. B. Use the Disable automatic restart on system failure option on the Advanced Boot Menu. C. Use the Safe Mode with Networking option on the Advanced Boot Menu. D. Use the Safe Mode with Command Prompt option on the Advanced Boot Menu.
B. Use the Disable automatic restart on system failure option on the Advanced Boot Menu. Explanation: By default, Windows is configured to reboot whenever a critical system error occurs (Blue Screen of Death). Use the Disable automatic restart on system failure option on the advanced boot menu to stop the automatic reboots. Safe Mode with Networking is a variation of Safe Mode that also loads networking components if the problem is related to a network component. Sate Mode with Command Prompt is a variation of Sate Mode that allows you to boot to a command prompt. The Last Known Good configuration option restores the registry to the Last working configuration. None of these options will stop the automatic reboots.
One day while trying to start your Windows XP computer, the system displays the following error: Windows could not start because the following file is missing or corrupt: Windows\systew32\ntoskrnl.exe. Please re-install a copy of the above file. The problem occurs immediately after the operating system loading message. You are unable to boot into Safe Mode. Which of the following will most likely fix the problem? (Select two.) A. Boot into the recovery console and run the fixboot command on the boot volume. B. Boot using the Last Known Good configuration. C. Boot into the recovery console and run bootcfg /rebuild. D. Boot into the recovery console and run the fixmbr command on the boot volume. E. Boot into the recovery console and perform an automatic operating system scan and repair.
C. Boot into the recovery console and run bootcfg /rebuild. & E. Boot into the recovery console and perform an automatic operating system scan and repair. Explanation: The error message indicates that the Ntoskrnl.exe file is missing or corrupt. This means that the boot loader program (NTLDR) is running and is trying to locate the Ntoskrnl.exe file in the location specified by the BOOT.INI file. If the BOOT.INI file is pointing to an invalid location, then run bootcfg /rebuild to rebuild the BOOT.INI file with valid operating system locations. If the BOOT.INI tile is pointing to the correct location, then you will need to replace or repair the missing or corrupt file. You can boot into the recovery console and perform an automatic scan and repair, or use the copy command to replace missing files. The error in this scenario is generated by the NTLDR program, which means that NTLÐR has been successfully loaded. Because NTLDR is running, you know that the master boot record has correctly pointed to the location of that file, so running fixmbr would be unnecessary. Run fixboot lithe system could not locate the NTLDR file on a valid partition. You cannot use the Last Known Good configuration because the system will not boot Into Sate Mode.
One day while trying to start your Windows 7 computer, the system displays the following error: Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Which of the following will most likely fix the problem? A. Boot into Safe Mode and restore to a Restore Point. B. Boot into the recovery console and copy the NTLDR file to the boot volume. C. Boot into the recovery environment and run the bootrec /rebuildbcd command. D. Boot into the recovery console and run the fixmbr command on the boot volume. E. Boot into the recovery console and run the bootcfg /rebuild command.
C. Boot into the recovery environment and run the bootrec /rebuildbcd command. Explanation: This error message is generated when the system cannot find the partition specified In the BCD database where the operating system files are located. For example, the database might be pointing to the D: drive for the operating system files, but that drive does not exist. Run the bootrec /rebuildbcd command to rebuild the boot loader database with a list of valid operating system locations. For Windows XP, run the bootcfg /rebuild command to repair the BOOT.INI file. You will not be able to boot into Safe Mode because the operating system files have not yet been loaded.
You have a Windows 7 system with two SATA hard drives, one used for the operating system and the other used for data. You have traced recent problems to a fault in the system motherboard. You replace the motherboard and reconnect all hardware. When you start the computer, the system shows the BIOS information screen, but then returns an error that an operating system could not be found. What should you do? A. Press F6 during startup and load the SATA drivers. B. Boot into Safe Mode and import the disks in Disk Management. C. Change the boot order in the BIOS. D. Boot into the recovery console and run the fixmbr command.
C. Change the boot order in the BIOS. Explanation: The most likely cause is that the boot order in the BIOS needs to be changed to boot from the system disk first. When you replace the motherboard, the BIOS and CMOS chips are replaced and previous boot settings are lost.
Rodney, a user in the research department, reports that he is getting STOP errors while using his Windows 7 computer. You ask Rodney if anything has changed recently on the computer. Rodney explains that he ran the installation program for his PDA and everything worked fine until he tried to hot sync. Now any time he hot syncs, he has to reboot the computer. You need to fix Rodney's computer and prevent Rodney from using the PDA until you can install an updated driver. What should you do? A. Boot the system using a Windows 7 installation disc, select the Startup Repair option. B. Reboot the system and select Safe Mode. Edit the properties of the PDAs driver in Device Manager and select Roll Back Driver. C. Reboot the system and select Safe Mode. Disable the PDAs driver in Device Manager. D. Reboot the system and select the Last Known Good Configuration from the Advanced Startup options. E. Re-Install Windows 7 from the installation disc.
C. Reboot the system and select Safe Mode. Disable the PDAs driver in Device Manager. Explanation: You should disable the driver. Although you might be able to disable the driver without booting in Safe mode, booting in Safe mode is a good way to prevent drivers that could interfere with your task from being loaded. Because the system can successfully boot and the error occurs after logon, the Last Known Good Configuration option will still load the drivers. Rolling back the driver will not help because the driver was not updated. Because the boot process is functioning, there is no indication that the boot sector or master boot record needs fixing using the Startup Repair. Reloading the system or performing a parallel installation will likely correct the problem, but this is unnecessary. A parallel installation would require another partition.
The video driver on your Windows 7 computer is preventing the system from starting up successfully. You have already downloaded an updated driver and copied it to the computer's hard drive. Which mode should you select from the Windows Advanced Boot Options menu to ensure that the system can complete the boot process? A. Enable Boot Logging B. Safe Mode with Networking C. Safe Mode D. Directory Services Restore Mode
C. Safe Mode Explanation: Safe Mode is the best choice. Safe Mode boots Windows with a limited set of devices. Once Windows is running, you can use operating system tools to make configuration changes that might help you start the system normally. Because you already have the driver copied to the local hard drive, there is no need for networking support. Directory Services Restore only applies to Domain Controllers. Boot Logging can be used to collect data about the boot process, but in this case, the video driver has already been identified as the cause of the problem.
One day while trying to start your Windows XP computer, the system displays the following error: invalid partition table Which of the following will most likely fix the problem? A. Boot into Safe Mode and restore to a Restore Point. B. Boot into the recovery console and run the bootcfg /rebuild command. C. Boot into the recovery console and copy the NTLDR file to the boot volume. D. Boot into the recovery console and run the fixmbr command on the boot volume.
D. Boot into the recovery console and run the fixmbr command on the boot volume. Explanation: This error message is generated by the BIOS code as it looks on the disk for the boot loader program. Using the list of devices configured In the BIOS, it checks the master boot record on hard disks to locate the active partition. If an active partition has not been set, or if the partition table in the master boot record is corrupt, you could see this message. Run fixmbr to try to correct the problem, or use a third-party utility to try and rebuild the master boot record and the partition table. Copying NTLDR to the partition will not work if the partition table is corrupt. For Windows XP, run the bootcfg /rebuild command to repair the BOOT.INI file. This file identifies the location of operating system files. You will not be able to boot into Safe Mode because the operating system files have not yet been loaded.
You're troubleshooting a computer running Windows 7. The operating system has halted and a blue screen has been displayed on the monitor with an error message. What is the first step you should take in troubleshooting the issue? A. Remove all memory modules and replace them one at a time until the error reappears. B. Update the BIOS. C. Uninstall the last application or system update that was installed. D. Search for the error in Microsoft's knowledgebase or in a search engine on the Internet. E. Check the voltage levels on the DC side of the power supply.
D. Search for the error in Microsoft's knowledgebase or in a search engine on the Internet. Explanation: The first thing you should do when a "blue screen of death" has been displayed is identify the source of the error by searching for the text of the error message In Microsoft's knowledgebase or across the Internet in general using a search engine such as Google or Yahoo. This will help you identify what's causing the problem so you can troubleshoot it.
You want to scan your system for changed system files and automatically revert to previous versions for any file that has been altered. You want the scan to run once the next time the system boots. Which command should you use? A. sfc /revert B. sfc /scanboot C. sfc /scannow D. sfc /scanonce
D. sfc /scanonce Explanation: Use sfc /scanonce to launch SFC the next time the computer boots. SFC scans every system file in the operating system for altered files. Altered files are then replaced with the original file from your DLL cache or installation media. Sfc /scannow scans the system and replaces altered files. Sfc /scanboot launches SFC every time the computer boots. Sfc /revert reconfigures SFC to its default setting.
