Question 1

You decide to edit the boot order for your Windows 10 computer using the MSCONFIG utility. To which file is this edit saved?

A)boot.ini
B)BCD
C)bootmgr
D)Ntoskrnl.exe

Answer 1

When you edit the boot order for a Windows 10 computer using the MSCONFIG utility, the changes are saved in the Boot Configuration Data (BCD) file. You can select the boot order on the Boot tab of the System Configuration utility (note that the OS you want to select must already be installed):

The BCD file is the file that replaced the boot.ini file. The boot.ini file was used in Windows XP and earlier, and the BCD file is used in Windows Vista and later. The BCD holds configuration data about which operating systems are installed. You cannot copy a BCD file from another computer and expect it to work properly. The MSCONFIG utility is used to edit the BCD file. You can also use Advanced Recovery Options and the BCDEdit.exe tool in Windows 7 and later to change the boot options. You can use the BCDBoot command to set up or repair the boot menu.

Question 2

You need to upgrade a computer running Windows 8.1 Core to Windows 10. To which editions of Windows 10 can this computer be upgraded? (Choose all that apply.)

Question 3

You need to view the contents of a Windows 10 update. Which command-line tool should you use?

A)XCOPY
B)EXPAND
C)COPY
D)EXTRACT

Answer 3

You can view the contents of a Windows 10 update file by using the EXPAND command.

EXTRACT allowed you to pull one or more files out of a CAB file. This command was deprecated in Windows XP and above.

COPY allows you to duplicate a file or folder.

XCOPY duplicates a folder, including subfolders and files.

To use the EXPAND command, run the CMD command to open the command-line prompt, and then type EXPAND. The command line options are as follows:

-r – renames expanded files
-D – displays the list of files in the source file
Source – specifies the source file to use
-F:filename – specifies the name of the files to expand from the source file
Destination – specifies the destination location

Question 4

Which of the following statements is true about an in-place upgrade and a clean installation?

A )An in-place upgrade can always be used when upgrading from a previous operating system version.

B) An in-place upgrade installs the operating system files and retains user settings.

C) A clean installation installs the operating system files and retains user settings.

D) A clean installation does not require the reinstallation of applications.

Answer 4

The difference between an in-place upgrade and a clean installation is that an in-place upgrade installs the operating system files and retains user settings, while a clean installation installs the operating system files and does not retain user settings. An in-place upgrade can only be used when the operating systems are closely related, and must follow a certain upgrade path. A clean installation will require the reinstallation of applications.

B) Running other applications may result in disk write operations forcing Disk Defragmenter to restart continually.

C) Disk Defragmenter requires exclusive access to drives.

D) Running applications prevent Disk Defragmenter from being launched.

Answer 9

Running other applications may result in disk write operations, forcing Disk Defragmenter to restart continually. Disk Defragmenter reorders file contents on the disk in an attempt to store each file in a contiguous sequence of disk storage blocks. Any application that is running and writing data to the disk may disrupt the ordering carried out by Disk Defragmenter and force the defragmentation process to be restarted.

Question 10

You are installing an operating system on a drive that appears to have sector issues. Which formatting option should you use?

A)ExFAT
B)Full Format
C)NTFS
D)Quick Format

Answer 10

When you are installing an operating system on a drive that appears to have sector issues, you should use full format. A full format will take much longer than a quick format because a full format checks for bad sectors. It is critically important that the boot drive be properly formatted with the correct partitions and format.

Question 21

Which security considerations should you take into account when installing and configuring applications on Windows desktops? (Choose all that apply.)

A) User privileges
B) Turning Windows features on or off
C) Remote PC access
D) Impact to device

Answer 21

You should consider the impact to the device, user privileges, and whether Windows features will be enabled or disabled as a result of the installation.

You should consider the impact to the device, specifically the application’s access to the device’s files, settings, and user accounts. If, for example, the application accesses information in the cloud, you might be vulnerable to an attack. You should also consider whether the application is allowed to make changes to the underlying operating system settings, registry keys, or inbound connections.

You might also want to consider which user privileges are required to install and run the application. User Account Control (UAC) will limit the users that will be able to install applications on a Windows computer. An administrative-level account is required to do this.

You should consider whether the application will enable or disable Windows features. If you have to disable Windows Firewall to install an application, what vulnerabilities does this expose?

Answer 23

The dir command locates all the files and directories that belong to the specified path and match the file name specified as part of the command. The D:\MYDOCS\FILECHK.* specification matches any file or directory that has the name FILECHK and any extension. The search starts with the D:\MYDOCS directory and searches all the subdirectories, as specified by the /s switch.
