To learn more about the DIR command, what would you enter at the command line? (Select the two best answers.)

A. DIR HELP
B. HELP DIR
C. DIR /?
D. DIR ?

Answers: A
Explanations
Use an uninterruptible power supply (UPS) to provide clean power and eliminate the voltage fluctuations—with the stipulation that the printer is not a laser printer! If it’s a laser printer, connect it to its own line conditioner. That is because of the load the laser printer puts on the device it plugs into. The question did not specify that this was a laser printer, and most friends of mine have inkjets. It’s not outside the realm of possibility, but it will be less likely, and that’s what you have to assume when taking the exam. As for the incorrect answers: a multimeter is what you would have used to figure out that the AC outlet was providing dirty power. A surge protector will not condition the voltage that is coming from the AC outlet; it will only protect against surges and spikes. A gas generator is a ridiculous option that would actually work in this scenario. However, it is not wise to keep a gas generator in the house; plus it will cost the friend more in money and maintenance as compared to a UPS.

Which of the following commands creates a new directory in the Windows Command Prompt?

A. CD
B. MD
C. RD
D. SD

Answers: B and D
ExplanationsThe share-level permissions must first be set to enable access to the user. Then the NTFS file-level “user” permissions must also be set; these take precedence over share-level, unless the share-level access is set to deny. Certificates are normally used in Internet or VPN sessions. Local user access is somewhat vague but doesn’t apply here because when a user connects to a shared resource, that person does so over the network to a remote computer.

Which user account permissions are needed to install device drivers on Windows Vista?

A. User

C. Administrator
D. Power user

Answers: A
ExplanationsThe TV tuner is used to enable the Live TV option in Windows 7 Media Center. This is usually the toughest part to configure on an HTPC. This is due to cable company regulations. However, TV tuners are also becoming more popular when used with over-the-air signals including HD, as long as you are within close proximity to a metropolitan area. A modem is used to make dial-up connections to the Internet.Video cards display video signal to a monitor or TV; often, HTPCs will have a video card with an HDMI output. The network adapter (also known as a network card or NIC) is used to connect to the LAN.

Where is the Windows Update feature located in Windows?

A. Start > All Programs > Accessories

C. Start > All Programs > Control Panel
D. Start > All Programs > Administrative Tools

Answers: D
Explanationstracert (short for trace route) can show the entire path between you and a final destination, displaying every router (or hop) in between. A similar command that gives slightly less information is pathping. ipconfig displays basic information about your network connection. ping tests your network connection against other hosts. nslookup enables you to look up name servers and run several commands when connected in the NSLOOKUP shell, thereby allowing you to configure and modify a name server.

Where would you go to start, stop, or restart services?

A. Computer Management
B. Task Manager
C. Performance Monitor
D. MMC

Answers: B
Explanations
The PC air intakes are probably clogged with cement dust. This will stop fresh, cool air from entering the PC and cause the CPU to overheat. That’s why the system won’t reboot immediately because the CPU needs some time to cool down. You should install a filter in front of the PC air intake and instruct the customer to clean the filter often. While you are working on the computer, you should clean out the inside of the system and vacuum out the exhaust of the power supply (without opening the power supply of course). If the PC had a virus, that might cause it to lock up or shut down, but you would be able to reboot the computer right away. Plus, there would probably be other indicators of a virus. The CPU heat sink could be an issue and could cause the same results, but it is less likely. Companies often buy computers from popular manufacturers such as Dell and HP; these computer manufacturers spend a lot of time designing their heat sink/fan combinations to work with the CPU. If the power supply was underrated, it would cause intermittent shutdowns, but not lockups. Nothing in the scenario would lead you to believe that the computer uses so many powerful components as to make the power supply underrated.

Which tool enables you to find out how much memory a particular application is using?

A. Msconfig
B. Task Manager
C. Chkdsk
D. System Information

Answers: C
Explanations
Adding the port number and name of service to the Windows Firewall Exceptions list is the correct answer. But I’m going to pontificate more as I usually do. Uninstalling and reinstalling the SP will not help this particular situation. By default, any Windows OS after and including Windows XP SP2 enables the Windows Firewall automatically and won’t allow inbound connections from the server to the network application. Therefore, you need to make an “exception.” You can access this in Windows XP by going to Local Area Connection Properties > Advanced tab. In Windows 7/Vista, use the Windows Firewall with Advanced Security: Start > All Programs > Administrative Tools. If you decide to add a port, you need to know the port number of the application. For example, RealVNC is normally port 5900 for incoming connections.

What is the minimum requirement of RAM for Windows XP Professional?

A. 64 MB
B. 128 MB
C. 256 MB
D. 32 MB

Answers: B
ExplanationsThe print spooler needs to be restarted on the computer that started the print job or the computer that controls the printer. This can be done in the Services console window or in the Command Prompt with the net stop spooler and net start spooler commands, or anywhere else where services can be started and stopped such as the Task Manager. Okay, that was an easy one, but the real exam will have a couple easy ones thrown in as well. Don’t think too hard when you actually do receive an easier question.

Which type of partition should an operating system be installed to?

A. Primary
B. Extended
C. Volume
D. Logical drive

Answers: C
ExplanationsStart with the physical! Check for a link light first. This tells you whether there is physical connectivity. Then, if necessary, you can, in order, test the patch cable, reconfigure TCP/IP, install drivers (from the manufacturer’s website, mind you), and finally replace the NIC.

What tool enables you to create a partition in Windows?

A. Disk Administrator
B. Disk Management
C. Computer Management
D. Disk Cleanup

Answers: A and D
ExplanationsCheck the basics first! Make sure the power cable wasn’t disconnected from the computer, and verify that the voltage switch is in the correct position. Kids like to play tricks on lab computers! A standard power strip should not overload with just two computers connected to it, but if it does, press the reset switch on the power strip. The monitor being unplugged could be a separate problem, but it won’t cause the computer to not power on. If the second computer works fine, then that tells you the power strip is plugged in.

Which file is the boot loader in Windows 7/Vista?

A. Winload.exe
B. BCD
C. Setup.exe
D. Ntoskrnl.exe

Answers: C
Explanations: What should have been port 143 was probably configured incorrectly if the person can send but not receive e-mail. The Internet Message Access Protocol (IMAP) receives e-mail and uses port 143. The Simple Mail Transfer Protocol (SMTP) uses port 25 by default to send mail but will use port 443 if SSL or TLS security is implemented. Port 110 is the POP3 e-mail port. POP3 also is used to receive e-mail, but not in this question’s scenario. By the way, another port that is used for SMTP is 587. This is done to avoid being blocked by ISPs and to reduce spam. Mobile devices such as Android phones can be a little more difficult to configure e-mail on, as compared to PCs. Be sure to work with mobile devices and go through the steps of setting up e-mail on both Android and iOS.

Answers: C and E
Explanations: If only one computer is connected to the switch, there shouldn’t be much activity. Rapidly blinking LED lights might lead you to believe that the computer’s network card (NIC) or the port on the switch is faulty. However, it could be that the person is sending a lot of data to himself while you are testing the network, but that would be strange and rare. The server doesn’t have anything to do with this, nor does the hard disk.

In Windows 7/Vista, an MMC is blank by default. What would you add to the MMC to populate it with programs?

A. Applets
B. Files
C. Directories
D. Snap-ins

Answers: C
Explanations: MAC filtering is used to restrict computers from connecting to a network; it is based on the physical Media Access Control (MAC) address of the computer’s network adapter. It works with wired or wireless connections. WPA is used to encrypt the wireless session between a computer and the wireless access point (WAP); its key code is required to gain access to the network. DHCP settings simply allow a specific range of IP addresses, and other IP data such as gateway address and DNS server address, to be handed out to clients. The SSID broadcast is the name of the wireless network, as broadcast out over radio waves by the WAP.

What is the minimum amount of RAM needed to install Windows Vista?

A. 128 MB
B. 256 MB
C. 512 MB
D. 1 GB

Answers: D
Explanations: 

The first thing you need to supply is the driver for any special SATA drives, SCSI drives, or RAID controllers. That of course is optional. If you have a typical SATA drive, Windows should recognize it automatically. Once Windows knows which hard drive to install to, partitioning, then formatting, and then configuration of settings can commence, in that order.

Windows service packs are ___________.

A. A new version of the operating system
B. Resource Kit utilities
C. Compilations of software updates and patches
D. Driver updates

Answers: A
Explanations: Internet Explorer (or any other web browser) is normally used to configure a router. It’s sometimes referred to as romming into the router because the configuration program is stored in the ROM chip of the router. You can type the IP address of the router into the Windows Explorer address bar, but that will simply open an IE (or other browser) tab. The Device Manager is where you enable and disable devices and install, update, and roll back drivers for devices. Msconfig is used to modify how the computer boots and to enable/disable programs and services.

Where is the Notification Area located in Windows 7?

A. In the System Properties dialog box
B. In the System32 folder
C. On the Taskbar
D. Within the Start menu

Answers: C
Explanations:HKEY_LOCAL_MACHINE is the registry hive that stores information about the programs Windows runs when it starts. The actual hives are stored in \%windir%\System32\Config. But it’s okay to call HKEY_LOCAL_MACHINE and the other HKEYs hives. Most technicians do it, and you might see them referred to that way on the exam as well. The HKEY_LOCAL_MACHINE hive is the one you will access the most often. You can configure advanced settings for TCP/IP, the GUI of the OS, and lots more from here. HKEY_CURRENT_CONFIG contains data that generated when the system boots; nothing is permanently stored. HKEY_USERS stores the information for each user profile. HKEY_CLASSES_ROOT contains information about registered applications and file associations.

What is the default file system used by Windows 7?

A. FAT32
B. CDFS
C. NTFS
D. FAT

Answers: D
Explanations: You want to set a new default printer in the OS because he has installed a new printer. This is usually done simply by right-clicking the printer and selecting Set as default printer. You might also see a question with the option to click File (or Printer). This is if you double-clicked the printer to open it and then selected the first menu. Unused printer drivers for older printers should be removed when the older printers are replaced.

Of the following, which is not a method of installing Windows 7?

A. Over the network
B. CD-ROM
C. DVD-ROM
D. USB flash drive
E. Image

Answers: A
Explanations: The classification of data helps prevent confidential information from being publicly disclosed. Some organizations will have a classification scheme for their data, such as normal, secret, and top secret. Policies are implemented to make top secret data the most secure on the network. By classifying data, you are determining who has access to it. This is generally done on a need-to-know basis. Social engineering is the art of manipulating people into giving classified information. A remote access server (RAS) allows users to connect remotely to the network. To protect the connection (and data that passes through it), an organization might opt to use a VPN or RADIUS server, or both. Wiping a hard drive is vague. How is it being wiped? If it is being formatted, then that is not enough to protect confidential information. You need to perform bit-level erasure with third-party software, degauss the drive, or destroy it to make sure that no one can access the data. The thing is that data is always stored somewhere on a server or NAS device, so properly disposing of a single hard drive doesn’t protect any and all confidential information from being publicly disclosed.
