Question 1

Sarah is trying to print a document from her workstation. She can see her document displayed in the print queue, but it does not print. The printer is fully functional. Which of the following steps should she take to print the document?

Accepted Answer

To fix this problem, restart the print spooler. To restart the spooler service, click Start, right-click My Computer, and then click Manage. Expand Services and Applications > Services. In the details pane, right-click the Print Spooler service, and then click Start.
Key Takeaway: Clearing the entries in the print queue or deleting and recreating the print object will not help solve this problem.

Question 2

You need to conduct some general maintenance on a computer running Windows 7. You want to defragment the primary drive, perform error checking, and backup the primary drive. Where are you able to accomplish these tasks?

Accepted Answer

The C: drive Properties box and Tools tab will contain the Defrag, Error Checking, and Backup options.
Key Takeaway: The properties box for a drive allows you to perform disk cleanup and backup, change sharing settings, set security settings and user disk space quotas.

Question 3

Overnight, the DHCP server went down. The server provides dynamic IP address for the computers in the office network (using the IPv4 standard). You have the server backup but not all of the computers can connect to the network. What command/commands do you use to reconnect the computers to the server and obtain an IP address?

Accepted Answer

Ipconfig /release and then ipconfig /renew will allow the computer to reconnect with a new IP address.
Key Takeaway: Using ipconfig /release will prompt the NIC to release the previously assigned IP address and the ipconfig /renew will send a request to the DHCP server for a new IP address.

Question 4

John is booting his computer for the first time in 2 weeks. After the CMOS set-up screen, the monitor displays an error message which states, "NTLDR is missing." Which of the following options should he use to fix this problem?

Accepted Answer

Use the Recovery Console to fix the "NTLDR is missing" error. You can fix missing or damaged boot files using the Recovery Console.
Key Takeaway: The most common causes of the "NTLDR is missing" error are:
1. The computer is booting from a non-bootable device.
2. HDD is not set up in the BIOS.
3. Corrupt NTLDR and/or NTDETECT.COM file.
4. Misconfigured boot.ini file.

Question 5

Amelia is experiencing problems with a slow start-up process when she switches on her computer. Which of these utilities can be used to stop certain applications from starting automatically when the computer boots up?

Accepted Answer

MSCONFIG is a utility that can be used to either allow or deny programs from starting automatically when the computer boots up. MSCONFIG can be activated by typing msconfig in the Run option on the Start menu.
Key Takeaway: When you install a number of applications on the computer, the amount of free RAM available decreases significantly. Apart from the fact that these applications use RAM when they run, most of them start automatically when the computer boots up. Initializing all these programs takes longer than usual, and this makes the user wait for longer periods before using the computer.

Question 6

On a Windows 7 computer, you need to modify the appearance of the taskbar (at the bottom). Which of the following is not a possible path for making this change?

Accepted Answer

The paths in A, B, and D will allow you to change the appearance of the taskbar.
Key Takeaway: It is useful to know more than one way to complete the same action. This can come in handy when the computer may not cooperate with your typical process.

Question 7

Which of the following is the best method for removing a flash drive that has been inserted into a USB port?

Accepted Answer

Flash drives should be removed from the computer using the Safely Remove Hardware icon in the notification area.
Key Takeaway: A USB drive has a file system, just like a hard drive does. If the power to the machine is cut or the drive is pulled out during a write, this will result in incomplete data and possibly a corrupted file system on the drive. The "Safely Remove Hardware" bit calls for all programs accessing the drive to complete whatever reads or writes they are performing, as the drive will be removed. When all I/O is complete, the OS removes the drive from its list of usable drives and then tells you it's safe to remove it.

Question 8

David installed a new set of drivers for one of his hardware components. Since then, the computer has not been able to boot to the OS. Which of the following is a possible first step towards resolving this problem?

Accepted Answer

Many times, a new set of drivers may not be compatible with the operating system. Hence, the computer fails to boot to the OS and freezes. Use the Last Known Good Configuration option from the advanced boot menu to start your computer. This will load the most recent settings that worked.
Key Takeaway: The Last Known Good Configuration feature is a recovery option that allows you to start your computer by restoring registry information and driver settings that were in effect the last time the computer started successfully.

Question 9

David configured a password to restrict access to the CMOS setup. Which of the following should he do to remove this password and access the CMOS setup?

Accepted Answer

To reset or bypass the CMOS password, clear the CMOS jumper on the motherboard. This clears all the CMOS settings, including the CMOS password.
Key Takeaway: The CMOS password is used to protect any unauthorized changes to the machine's basic configuration. If you forget the password, you will not be able to enter the CMOS setup. To clear this password and enter the setup, do the following:
1. Locate the CMOS jumper on the motherboard.
2. Remove this jumper from its default location.
3. Refer to the manual for the password reset location. Ideally pin #1 and #2 are default, and pin #2 and #3 are used for a password reset.
4. Keep the jumper in the reset location for 20-30 seconds and then place it in the default location.

Question 10

Hilda is experiencing a problem with her computer. The computer does not boot to the operating system, and the message "NTLDR is missing" appears every time the system is turned on. What troubleshooting step should she consider?

Accepted Answer

Use the Recovery Console to fix the "NTLDR is missing error." You can fix missing or damaged boot files using the Recovery Console, a text-based startup of Windows that gets you to a command prompt similar to the Windows command prompt. Here you can copy or expand the system and booting files.
Key Takeaway: The most common causes of the "NTLDR is missing" error are:
• The computer is booting from a non-bootable device.
• HDD is not set up in the BIOS.
• Corrupt NTLDR and/or NTDETECT.COM file.
• Misconfigured boot.ini file.

Question 11

John is working in the network repair and troubleshooting unit with a DSL service provider. He is trying to fix an issue with packets being lost en route to the destination. Which of these utilities can he use to find the number of hops a packet takes from the source to the destination?

Accepted Answer

Tracert is the network troubleshooting tool that displays the number of hops taken by a packet from the source to the destination. The syntax for a tracert command is tracert[hostname], for example tracert 11.1.0.1.
Key Takeaway: Tracert is the most commonly used command for network troubleshooting under conditions of intermittency or packet loss. The timing information from tracert can be useful for detecting a malfunctioning or overloaded router.

Question 12

David has been told by a technical support executive to clear all temporary Internet files from his computer to improve the Internet access speed and reliability on his computer. Which of the following utilities should he use?

Accepted Answer

Internet Explorer copies any images or HTML files from websites you visit frequently to a directory on your hard drive. These cached contents allow for faster access to pages that have been already accessed, but a large number of temporary Internet files can slow down your computer. Clean this folder regularly. To use the Disk Cleanup utility:
1. Click Start, and then click Run. Type cleanmgr, and then click OK.
2. Select the drive letter for the current Windows installation and then click OK.
3. Select Temporary Internet Files from the list.
4. Uncheck all the other entries and click OK.
5. Click Yes to confirm deletion.

Question 13

Which command line option allows you to open the Windows registry?

Accepted Answer

The command line syntax regedit will open the Registry window for editing.
Key Takeaway: The Registry is a database used to store settings and options. It contains information and settings for all the hardware, software, users, and preferences of the PC. Whenever a user makes changes to a Control Panel settings - or to File Associations, System Policies or installed software - the changes are reflected and stored in the Registry.

Question 14

Martha gets an error message every time her system boots up. The error message reads, "A service did not start." Where is the best place to look for more information on this error message?

Accepted Answer

All system logs related to services, driver, and startup can be viewed in the System Log section of the Event viewer. To open Event viewer, choose Start > Programs > Administrative Tools > Event Viewer. Choose the System link to view the system logs.
Key Takeaway: There are three types of event logs that can be viewed in the Events viewer: system logs, applications logs, and security logs. In the System section of the Event viewer you can find all system-related logs, like services, drivers, startup, etc. The Application and Security sections, on the other hand, can be used to find all information on application-related and security-related events.

Question 15

In Windows 7, you type ipconfig in the command line utility and view the results. You decide to type in ipconfig /all to see the different options. Which pieces of information are displayed when you type ipconfig /all but not when you type ipconfig?

Accepted Answer

In Windows 7, the ipconfig /all command will display the IP addresses of the DHCP and DNS Servers.
Key Takeaway: Also, the ipconfig /all command will display the acquisition and expiration dates for the DHCP lease on the host computer.

Question 16

You are working on an older network with some systems that haven't yet been upgraded. What command on a Windows system will allow you to see a list of the users connected to your system?

Accepted Answer

The NBTSTAT command (NBTSTAT -C) allows you to see a list of the users connected to your system in an older network.
Key Takeaway: NBTSTAT is a diagnostic tool for help troubleshooting the NetBIOS name resolution. Running NBTSTAT -C shows a cache of all the users and their IP addresses that are currently connected to a system (for instance, multiple users logged into one remote server through RDP sessions). NETSTAT is similar but shows the same information for TCP and UDP ports (rather than NetBIOS). Neither of the other two commands exists or is correct.

Question 17

From the Windows command line, which command brings up a list of tasks similar to Windows task manager?

Accepted Answer

From the command line, TASKLIST will bring up a list of tasks similar to Windows task manager.
Key Takeaway: TASKLIST is a command line version of the Windows Task Manager (which can be launched from the command line with the TASKMGR command). TASKKILL can be used in conjunction with TASKLIST to identify a bad process and kill it. TASKS is not a command.

Question 18

Which of the following commands allows you to remotely shut down a Windows computer?

Accepted Answer

The command SHUTDOWN -M \COMPUTERNAME allows you to remotely shut down a Windows computer.
Key Takeaway: The SHUTDOWN command allows you to shut down a Windows computer from the command line. SHUTDOWN -S shuts down the local computer, and SHUTDOWN -M shuts down a remote computer, \COMPUTERNAME defining the name of that computer.

Question 19

Which of the following commands allows you to create a new directory from the Windows command line?

Accepted Answer

The MD command allows you to create a new directory from the command line.
Key Takeaway: To create a new directory, the MD (Make Directory) command allows you to do so in a Windows environment. CD (Change Directory) lets you move between directories, RD (Remove Directory) deletes the directory, and DIR lists the contents of the current directory.

Question 20

You want to remove an empty directory you were using for testing, called TEST, through the Windows command line interface. What command would you use to do this?

Accepted Answer

To remove an empty directory you were using for testing, called TEST, use the command RD TEST.
Key Takeaway: The command RD (Remove Directory) allows you to delete empty directories (no contents within the folder are allowed). DEL is a command for deleting files, DIR lists the contents of the current directory, and REMOVE is a Unix command.
