The hard drive performance on your Windows 7 workstation has deteriorated over time. To attempt to help performance, you want to ensure that files on the hard drive are written in contiguous blocks. Which administrative tool should you use to make this happen?
Disk Management
Disk Defragmenter
Disk Optimizer
Disk Defragmenter
When files are written to a hard drive, they’re not always written contiguously or with all the data in a single location. Defragmenting a disk involves analyzing the disk and then consolidating fragmented files and folders so that they occupy a contiguous space (consecutive blocks), thus increasing performance during file retrieval. The executable for Disk Defragmenter is DEFRAG.EXE
A member of your sales team wants to work from a remote location while traveling. The location he is going to does not have high-speed Internet, and he will be connecting to the network using a modem. When Windows Vista asks what type of networking connection he wants to establish, what should he choose?
Wired
Wireless
Dial-up
Dial-up
If you are using a modem to connect to the Internet, then the type of connection you are establishing is a dial-up connection. Internet access will be slow and painful!
What is the name of the user interface introduced with Windows 8?
Aero
Metro
WinPE
Metro
Microsoft came up with a new user interface for Windows 8. This was originally called the Metro interface, but the name was changed after its release to the new Windows UI (or the Windows 8 UI)
One of your workstations is running Windows 7 and has been occasionally crashing. You believe it’s an OS issue and not a hardware issue. You decide to upgrade the computer to Windows 8.1; however, you want to avoid continuing to have errors if they were software related. What type of installation should you perform?
Unattended
Migration
Clean
Clean
The best plan in this scenario is to format the hard drive, which by definition makes it a clean installation
You have a Windows 7 command prompt open. You are in the D:\users directory and want to copy all 20 of the files with a .doc extension into the D:\files directory. Which of the following statements is true?
You need to copy the files one at a time.
You can use the command copy *.doc d:\files.
You can use the command copy all.doc d:\files.
You can use the command copy *.doc d:\files.
The copy command makes a copy of a file in a second location. (To copy a file and then remove it from its original location, use the move command.) One useful tip is to use wildcards. For example, the asterisk (*) is a wildcard that means everything. So, you could type copy *.exe to copy all files that have an .exe filename extension, or you could type copy . to copy all files in your current directory. The other popular wildcard is the question mark (?), which does not mean everything but instead replaces one character. The copy abc?.exe command would only copy exe files with four-letter names of which the first three letters are abc
After you install Windows 8.1, you notice that an application called Windows Firewall is enabled. What is Windows Firewall designed to help protect your computer against?
Spyware
Fires
Malicious network traffic
Malicious network traffic
Windows 7 incorporates Windows Firewall, which can be used to stop incoming and outgoing network traffic. Traffic is allowed or denied by specific rules that are part of an access control list (ACL). By default, Windows Firewall blocks incoming traffic. One example of custom configuration is to create exceptions, where you can specify the incoming traffic you want to allow through
A Windows Vista user uses a lot of memory-intensive applications and has been recently getting “out of memory” error messages. Her computer has 16 GB RAM and can’t be upgraded any further. You want to ensure that her system has ample virtual memory as well; what is the minimum recommended size that her swap file should be?
16 GB
24 GB
48 GB
24GB
In general, the swap file should be at least 1.5 times the amount of RAM in the machine. You should place the swap file on a drive with plenty of empty space. As a general rule, try to keep 20 percent of your drive space free for the overhead of various elements of the OS, like the swap file. Do not set the swap file to an extremely small size. If you make the swap file too small, the system can become unbootable, or at least unstable
You are going to install a Windows 8.1 workstation from an image located on a server. What does the workstation need to support to enable this installation?
Netboot
PXE boot
USB boot
PXE boot
An install can be started many ways—with a USB drive, a DVD, and so on—and an image and setup files can also be located on and installed from a network, thus saving you from having to keep all the files on the local machine. Often called a PXE-initiated boot (for Pre-boot Execution Environment), it allows the workstation involved in the installation to retrieve the files from the network, as needed, and configure variables accordingly
The ability to have a Windows Taskbar appear on multiple monitors was introduced with what version of Windows?
Windows 8
Windows 7
Windows Vista
Windows 8
Multiple monitors have been available with Windows for some time, but not until Windows 8 has it been possible to have a Taskbar appear in each monitor
You have chosen to install Windows 8 Pro on a workstation that is currently running Windows 7 Professional. You choose a Custom installation and format the hard drive. What type of installation are you performing?
Migration
Clean
Upgrade
Clean
Whenever you format the hard drive, the old operating system is removed. Therefore, it is a clean install
You are at a Windows 8 command prompt. Which command allows you to copy files and directories, copy NTFS permissions, and mirror a directory tree?
copy
xcopy
robocopy
robocopy
The robocopy utility (Robust File Copy for Windows) is included with recent versions of Windows and has the big advantage of being able to accept a plethora of specifications and keep NTFS permissions intact in its operations. The /mir switch, for example, can be used to mirror a complete directory tree
You need to install Windows 7 onto several client computers that currently have no OS. You have created a PXE server and will perform the installation over the network. What is required to create the PXE environment?
WinPE
WinRE
A flash drive
WinPE
You can boot a PC over the network (rather than from a DVD, USB, or hard disk) with the Windows Preinstallation Environment (WinPE), which is a stub operating system that creates a Pre-boot Execution Environment (PXE). Netboot is the process of booting the OS from the network, such as from a thin client
A user has poor eyesight and is having trouble reading the small fonts on his monitor, including Windows Desktop icons. What should you do to make everything on the Windows Desktop appear larger?
Open Control Panel ➢ Appearance and Personalization and decrease the resolution.
Open Control Panel ➢ Appearance and Personalization and increase the resolution.
Open Control Panel ➢ Appearance and Personalization and decrease the refresh rate.
Open Control Panel ➢ Appearance and Personalization and decrease the resolution.
The screen resolution determines the number of pixels that go across and down to make up the screen image. Decreasing the resolution in effect makes each pixel bigger, thereby making images on the screen larger. Resolution, color depth, and refresh rate are set in Display or Display Settings in Control Panel
You are installing a Windows Vista workstation. When you’re joining the network, it asks for the location of your computer. The choices are Home, Work, and Public. Which of the following statements about these choices is true?
Home has network discovery turned on and Windows Firewall turned off.
Home and Work have network discovery turned on but Windows Firewall turned off.
Home and Work have network discovery turned on.
Home and Work have network discovery turned on.
Both the Home and Work settings for Windows Vista and Windows 7 have network discovery on by default. This means that you can see other computers and other computers can see you. If you choose Public, network discovery is turned off. None of the options affects Windows Firewall
A Windows 7 computer in your office is being used as a file server by the sales team. There is a folder on the D: drive named DailyReports where the sales team files their reports. The D: drive is now full. What is the easiest way to provide more capacity and not disrupt access to the folder?
Mount a new hard drive as a subfolder in DailyReports.
Extend the D: partition so it has more room.
Add another hard drive and create an array for the D: drive.
Mount a new hard drive as a subfolder in DailyReports.
By mounting a drive, you can map a folder or subfolder to empty space on another hard drive or partition. For example, if the computer has a second hard drive with a partition that has space, you can create a folder there and then mount it as a subfolder of the DailyReports folder on the D: drive
