About the Exam MD-100: Windows Client Exam

Windows client support requires choosing the right interface or utility for each task and understanding how configuration affects users and devices. The practice material includes locating active-hours settings for updates, managing services through a console, and recognizing Group Policy as a means of applying centrally controlled settings in a domain. Other scenarios involve setting compatibility options for older applications, creating compressed archives, and sharing folders with Windows permissions. Troubleshooting questions touch on scanning protected system files with a built-in command and checking device status and drivers in Device Manager. These tasks help connect Windows settings, administrative tools, and user-facing features to practical support decisions, such as when to adjust configuration, inspect hardware status, or address storage and file-access needs.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A Windows user wants to copy text or an image from one app and paste it into another. Which keyboard shortcut copies the selected content to the clipboard?

  1. ACtrl+C
  2. BCtrl+Z
  3. CAlt+F4
  4. DWin+L
Show answerCorrect answer: A

Ctrl+C copies selected content to the clipboard. Ctrl+Z undoes an action, Alt+F4 closes the active window, and Win+L locks the device.

Question 2

A user wants Windows to install updates outside their usual work hours. Which Settings area is the most direct place to configure the time period when the device is typically in use?

  1. APersonalization > Themes
  2. BWindows Update > Change active hours
  3. CAccounts > Sign-in options
  4. DSystem > About
Show answerCorrect answer: B

Active hours help Windows avoid automatically restarting the device during the times the user typically uses it. The setting is available in the Windows Update settings area.

Question 3

A technician wants to see which Windows services are running and change a service's startup behavior. Which built-in console is designed for this task?

  1. AServices
  2. BDisk Cleanup
  3. CWindows Memory Diagnostic
  4. DOn-Screen Keyboard
Show answerCorrect answer: A

The Services management console lists installed services, their status, and startup configuration. Changes should be made carefully because services may be required by Windows or installed applications.

Question 4

A Windows device is connected to a domain network, and an administrator wants to apply centrally managed user and computer settings. Which technology is commonly used to deliver those settings?

  1. AGroup Policy
  2. BStorage Sense
  3. CWindows Sandbox
  4. DNearby sharing
Show answerCorrect answer: A

Group Policy allows administrators to centrally configure supported Windows settings for users and computers, commonly in an Active Directory domain environment. The other choices serve unrelated functions.

Question 5

A user wants to run an older application that behaves incorrectly on a current Windows version. Which built-in option can apply compatibility settings to that application?

  1. AProgram Compatibility Troubleshooter
  2. BWindows Memory Diagnostic
  3. CDisk Cleanup
  4. DWindows Security protection history
Show answerCorrect answer: A

The Program Compatibility Troubleshooter can identify and apply compatibility settings for older applications. The other tools are intended for memory testing, storage cleanup, or reviewing security detections.

Question 6

A user needs to create a compressed archive containing several files using built-in Windows features. Which action is appropriate in File Explorer?

  1. ASelect the files, open the context menu, and choose a ZIP compression option
  2. BOpen Device Manager and scan for hardware changes
  3. CUse the taskbar search box to change the screen resolution
  4. DOpen Windows Security and select App & browser control
Show answerCorrect answer: A

File Explorer provides a context-menu option to compress selected files into a ZIP archive on supported Windows versions. This is useful for packaging files for storage or transfer.

Question 7

A user suspects that a Windows system file is damaged. Which built-in command can scan protected system files and attempt to repair them?

  1. Asfc /scannow
  2. Bipconfig /release
  3. Cnet use
  4. Dtasklist

Preparation tips

  • Practice distinguishing the roles of Device Manager, Services, and other built-in Windows management consoles by matching each to a specific support task.
  • Review how Windows permissions apply to local folder sharing, and distinguish access granted to network users from merely locating a folder.
  • Use Windows Settings to locate update active-hours and storage cleanup controls; note what each setting changes on the device.
  • Compare the purpose of System File Checker with application compatibility settings so you can select the appropriate response to damaged system files versus older software behavior.
