When touches register in the wrong spot, calibration is usually the issue. Ghost touches or random taps are often caused by electrical interference or dirt on the screen. If the display works but there is no touch response, the USB cable for touch input is probably disconnected.

3. What is a key benefit of using Groups when managing users with Local Users and Groups in Windows?

  • It simplifies user management by assigning permissions through group membership.
  • It assigns a unique permission set to each individual user account.
  • It ensures that all users are automatically given administrative rights by default.
  • It allows temporary users to save files that persist after logoff.

Using Groups allows administrators to efficiently manage permissions by assigning users to roles with predefined access, instead of configuring each user individually.

4. What is one key benefit of using Google Drive for Desktop instead of only accessing Google Drive through a web browser?

  • It lets users open and save files directly from File Explorer, with automatic cloud syncing.
  • It enhances file security by requiring users to confirm each file change with two-factor authentication.
  • It allows users to edit shared files only when offline, preventing conflicts during collaboration.
  • It moves all Google Drive files permanently to the local device to speed up performance.

Google Drive for Desktop integrates with File Explorer, allowing users to work on files locally while syncing changes automatically to the cloud, eliminating the need for manual uploads.

5. Jordan is an employee at a company where everyone logs in using domain accounts connected to the organization’s network. He forgot his password and cannot access any of his files or email. As the IT support technician responsible for helping him regain access, what is the correct way to reset his password?

  • Log into his workstation and use the Control Panel to reset the password.
  • Use Local Users and Groups Manager to reset his account locally.
  • Open Active Directory Users and Computers (ADUC) on a secure workstation and reset his password from there.
  • Have Jordan wait for the account to reset itself after multiple failed attempts.

Since Jordan is using a domain account, the right approach is to reset his password using the Active Directory Users and Computers (ADUC) tool on a secure workstation with administrative access.

6. Which statement provides the description of directory services in IT support?

  • They function as cloud-based tools for internet applications and store file permissions and encryption keys.
  • They store file permissions and encryption keys for secure data storage.
  • They replace the need for user authentication across different systems.
  • They manage user identities and access to both local and cloud-based network resources.

Directory services are used to manage user identities and control access to files, applications, and systems, both on local networks and in the cloud. This helps enforce security policies and simplifies authentication.

7. A user reports that their office printer can no longer scan or send faxes, even though printing still works. The printer is connected over Wi-Fi and is a multi-function device (MFD). What is the most likely cause of this issue?

  • The printer’s paper tray is overloaded.
  • The printer’s multi-function software or drivers may not be fully installed or have become corrupted.
  • The phone line service is down.
  • The scan-to-cloud settings are misconfigured.

Multi-function printers rely on full-featured software drivers to support scanning, faxing, and other non-print functions. If these drivers are outdated, missing, or corrupted, printing may still work, but scanning or faxing may fail. Reinstalling or updating the driver often resolves the issue.

8. A user says their external USB drive appears in File Explorer, but they cannot find any of their files. What is the most likely next troubleshooting step?

  • Format the drive to restore file visibility.
  • Restart the system and run the antivirus.
  • Replace the USB drive with a new one immediately.
  • Check if the files are hidden or if the drive uses encryption.

When a drive appears but no files are visible, it is often due to hidden files, encryption, or incompatible file systems—these should be checked before taking more drastic action.

9. An IT technician is helping a user set up secure access to their cloud account. Instead of sending a code via email, the technician recommends installing an app on the user’s phone that generates a temporary login code. This code refreshes every 30 seconds and is never sent over the internet. What type of multifactor authentication method is the technician recommending?

  • Authenticator application using a time-based one-time password (TOTP).
  • SMS-based two-factor authentication.
  • Biometric authentication using a fingerprint scanner.
  • Smart card-based authentication with a physical token.

The technician is recommending a secure MFA method where an authenticator app like Microsoft or Google Authenticator generates a temporary code based on time and a shared secret, reducing the risk of interception.

10. What is a key function of Microsoft Entra ID in IT support for cloud environments?

  • It works with Microsoft 365 and does not integrate with other SaaS apps to enhance focus and simplicity.
  • It replaces all local user accounts with cloud-based ones automatically.
  • It manages on-premises user accounts and local devices.
  • It enables single sign-on (SSO) and multi-factor authentication (MFA) for cloud and hybrid applications.

  • It refreshes and reapplies Group Policy settings for the computer and signed-in user.
  • It creates a new Group Policy Object and links it to a domain.
  • It resets all user account passwords stored in the Group Policy Object.

The gpupdate command is used to immediately apply GPO settings without waiting for the automatic refresh cycle, ensuring updated policies are enforced right away.

12. A support technician is helping a user who cannot hear any sound from wireless headphones during a virtual meeting. What is the most likely the reason?

  • The computer’s speakers are likely to be physically damaged.
  • The headphones are plugged into the wrong USB port.
  • The meeting software does not support headphones.
  • The headphones are not properly connected via Bluetooth.

Wireless headphones use Bluetooth to connect to the computer. If there is no audio, the first step is to check whether the Bluetooth connection is active and paired correctly.

13. An employee contacts IT support because the employee can’t see the shared folder for their department. The technician checks the connection to the internal server and sees that the SMB protocol isn’t responding. The user can still access internet services, but not the shared drive. What is the most likely cause of the problem?

  • The user’s computer cannot connect to the company’s SMB file sharing server.
  • The user needs to reinstall their Google Drive or Dropbox sync app.
  • The user’s internet browser settings have blocked access to cloud storage.
  • The shared drive files were accidentally deleted from the local Downloads folder.

SMB is a protocol used for accessing shared drives on internal servers. If it isn’t working, users may lose access to those shared folders, even if internet-based services are still available.

14. Match the printer issue to the most likely cause.

  • Reset the device to factory settings.
  • Restart the user’s Wi-Fi router.
  • Reinstall the teleconferencing app.
  • Check if the built-in camera is covered or disabled.

Cisco DX devices have built-in cameras for video calls. If the user cannot see themselves, it is often because the camera is covered, turned off, or disabled. Always start with the simplest and most likely causes before moving on to more complex solutions.

17. Which permissions describe the main difference between the Viewer, Commentor, and Editor roles in Google Drive?

  • Viewer can download files, Commentor can change text, and Editor can only add suggestions.
  • Viewer can change formatting, Commentor can change text, and Editor can change permissions.
  • Viewer can share files, Commentor can delete content, and Editor can only see content and post suggestions.
  • Viewer can only read content, Commentor can leave feedback, and Editor can make changes and share the file.

Google Drive permissions let the user choose what level of access others have – Viewer for seeing the file, Commentor for giving feedback, and Editor for full editing and sharing rights.

18. A receptionist at a law office is trying to send a fax to a client but keeps getting an error. She confirms the number is correct and retries several times, but the fax still won’t go through. The phone cord seems fine, and she hears no dial tone when she tests the line. What is the most likely issue?

  • The fax resolution setting is too high for the recipient’s machine.
  • The fax machine has too many pages in the feed tray.
  • The recipient’s line is busy and needs more time.
  • The phone cable might be in the wrong port on the fax machine.

A common reason for no dial tone on a fax machine is that the phone line is plugged into the wrong port. Be sure the line is connected to the port labeled “LINE” on the back of the fax device.
