Question 1

A technician needs to dispose of several old CRT monitors from an office. What is the proper disposal method according to environmental safety regulations?

Accepted Answer

Take them to a certified e-waste recycling center.. CRT monitors contain hazardous materials such as lead, phosphor, and other heavy metals that are harmful to the environment if disposed of in landfills. Certified e-waste recycling centers follow strict environmental regulations to safely dismantle and recycle these components, preventing toxic substances from contaminating soil and groundwater.

Answer

Place them in the regular dumpster for bulk trash pickup.

Answer

Smash the glass and separate the components for metal recycling.

Answer

Donate them to a local school for reuse.

Question 2

A user reports that their Windows 11 laptop can see the office Wi-Fi network but fails to connect, displaying 'Can't connect to this network'. Other users with the same laptop model connect without issues. The network uses WPA2-PSK with AES. What should you check first?

Accepted Answer

Forget the network on the laptop and reconnect by entering the passphrase again.. A mismatch in the saved passphrase is a common cause of connection failures when the network is visible. The correct answer is to forget the network and re-enter the correct passphrase. This tests troubleshooting skills for wireless authentication issues.

Answer

Update the wireless adapter driver.

Answer

Change the router's security protocol to WPA3.

Answer

Disable the firewall on the laptop.

Question 3

A user reports that their Android phone automatically switches from Wi-Fi to cellular data when the Wi-Fi signal is weak, even though they want to stay on Wi-Fi. Which setting should you configure to prevent this behavior?

Accepted Answer

Disable 'Switch to mobile data' in Wi-Fi settings. The 'Switch to mobile data' or 'Smart Network Switch' option in Android Wi-Fi settings automatically transitions to cellular when Wi-Fi is weak. Disabling this keeps the device connected to Wi-Fi, addressing the user's complaint. This is a common mobile OS feature for network management.

Answer

Turn off Bluetooth

Answer

Disable 'Mobile data always active' in Developer Options

Answer

Enable Airplane Mode

Question 4

A client wants to upgrade their entire office of 50 computers and asks for advice on environmentally friendly disposal of the old units. Which approach best aligns with environmental best practices?

Accepted Answer

Contract a certified e-waste recycling company to handle the disposal.. Certified e-waste recycling companies follow strict environmental regulations (e.g., the Basel Convention and local e-waste laws) to ensure hazardous materials like lead, mercury, and cadmium are safely extracted and disposed of, while also securely destroying data through methods such as degaussing or physical shredding. This approach minimizes environmental harm and aligns with the EPA's recommended practices for responsible electronics recycling.

Answer

Donate the computers to a local school without wiping data.

Answer

Sell the computers to a scrap metal dealer.

Answer

Have employees take the computers home for personal use.

Question 5

During a software installation, a technician receives an error that the system does not meet the minimum requirements. The technician decides to override the check by modifying the registry. What safety procedure should be followed before making registry changes?

Accepted Answer

Create a system restore point.. Creating a system restore point before modifying the registry is the correct safety procedure because it captures the current system state, including registry keys, drivers, and system files. If the registry edit causes instability or boot failure, the restore point allows the technician to revert the system to its previous working configuration without data loss. This is a standard best practice for any registry modification, as even minor errors can render the system unbootable.

Answer

Disable User Account Control (UAC).

Answer

Run the installation as an administrator.

Answer

Close all other running applications.

Question 6

A technician is troubleshooting a server that repeatedly trips the circuit breaker in the data center. The server is plugged into a power strip that is also serving two other high-power devices. What is the most appropriate safety and troubleshooting step?

Accepted Answer

Move one of the other high-power devices to a different circuit and plug the server directly into a wall outlet on its own circuit.. The repeated tripping indicates the circuit is overloaded. The safest and most effective step is to redistribute the load by moving one high-power device to a different circuit and plugging the server directly into a dedicated wall outlet. This isolates the server's power draw and prevents overloading the shared circuit, addressing the root cause without bypassing safety limits.

Answer

Replace the power strip with a higher-rated one and reset the breaker.

Answer

Reset the breaker and use a UPS with a higher wattage rating.

Answer

Install a larger circuit breaker in the panel to handle the load.

Question 7

A security incident occurs when an unauthorized user gains access to a server because a technician left a default password unchanged after a system rebuild. The rebuild was documented, but the password change was not. What documentation failure does this highlight?

Accepted Answer

The change log did not list the specific configuration changes made.. The documentation failure is that the change log did not list the specific configuration changes made. In this scenario, the system rebuild was documented, but the critical detail of changing the default password was omitted. Proper change management requires that every configuration change, including password updates, be explicitly recorded in the change log to ensure accountability and traceability. Without this record, the security incident occurred due to an undocumented deviation from security best practices.

Answer

The change log did not include a rollback plan.

Answer

The change request was not approved by the change advisory board.

Answer

The technician did not perform a post-implementation review.

Question 8

A user reports that their workstation is running slowly and they see a pop-up claiming their files are encrypted and a ransom must be paid. They cannot open any documents. What type of malware is most likely responsible?

Accepted Answer

Ransomware. Ransomware encrypts files and demands payment for decryption. This scenario describes classic ransomware behavior, where the user is locked out of their data and a ransom note is displayed.

Answer

Spyware

Answer

Trojan horse

Answer

Rootkit

Question 9

A technician is troubleshooting a wireless network where users report intermittent connectivity and slow speeds. The network uses WPA2-Enterprise with EAP-TLS and certificate-based authentication. The technician notices that the RADIUS server logs show frequent certificate validation failures. What is the most likely root cause?

Accepted Answer

Client devices have expired or untrusted certificates.. The RADIUS server logs show frequent certificate validation failures, which directly points to an issue with the certificates presented by the clients during EAP-TLS authentication. In WPA2-Enterprise with EAP-TLS, both the server and client must present valid certificates; if client certificates are expired or untrusted, the RADIUS server will reject the authentication, causing intermittent connectivity and slow speeds as clients fail to re-authenticate or roam.

Answer

The access point's firmware is outdated, causing packet loss.

Answer

The RADIUS server's certificate has expired.

Answer

The wireless channel is overlapping with neighboring networks.

Question 10

A user calls the help desk because they cannot access a shared folder on the network. The user's account is part of the 'Sales' group, which has 'Read' permission, but the user needs to modify files. What is the most efficient way to grant the required access?

Accepted Answer

Add the user to a group that has 'Modify' permission. Adding the user to a group with 'Modify' permissions is efficient because it avoids individual permission assignments and follows the principle of group-based access control. This ensures the user can edit files without overcomplicating permissions.

Answer

Assign 'Full Control' to the user's account directly

Answer

Change the folder's sharing settings to 'Everyone' with 'Read/Write'

Answer

Remove the user from the Sales group and add them to a new group with 'Read' permission

Question 11

A customer reports that their Windows 11 PC is experiencing intermittent application crashes and you suspect file corruption. You need to run a system file check without using the full Windows interface. Which administrative tool can you launch from the Run dialog to open a command prompt with the necessary permissions?

Accepted Answer

Type 'cmd' in the Run dialog and press Ctrl+Shift+Enter. Pressing Ctrl+Shift+Enter while typing 'cmd' in the Run dialog launches Command Prompt with administrator privileges, which is required to run the System File Checker (sfc /scannow) to repair file corruption. This bypasses the full Windows interface and provides the necessary elevated permissions.

Answer

Type 'cmd' in the Run dialog and press Enter

Answer

Type 'powershell' in the Run dialog and press Enter

Answer

Type 'msconfig' in the Run dialog and press Enter

Question 12

A technician is troubleshooting a computer that displays a fake security alert claiming the system is infected and urging the user to call a toll-free number. The alert cannot be closed and appears on top of all other windows. What is the best removal approach?

Accepted Answer

Restart the computer and press F8 to boot into Safe Mode with Networking, then run a malware scan.. This is a tech support scam, a form of scareware that uses a persistent pop-up. Booting into Safe Mode with Networking allows the technician to run an anti-malware scan without the rogue process interfering. Safe Mode loads only essential drivers, preventing the scareware from starting.

Answer

End the process 'svchost.exe' in Task Manager.

Answer

Call the toll-free number to get help removing the alert.

Answer

Use System Restore to revert to a previous restore point.

Question 13

A user reports that their computer has been acting strangely: files are missing, and the mouse cursor moves on its own, opening programs and typing messages. The technician suspects a remote access Trojan (RAT). What is the most effective immediate action to stop the unauthorized access?

Accepted Answer

Disconnect the Ethernet cable and disable Wi-Fi.. A RAT gives an attacker remote control of the system. The immediate action is to disconnect the computer from the network, which cuts off the attacker's connection. After isolation, the technician can run scans and remove the malware. Continuing to work while connected risks data theft or further damage.

Answer

Run a full antivirus scan while the user is logged off.

Answer

Change the user's password and log off.

Answer

Restore the system to a previous restore point.

Question 14

A user's Windows 10 PC is infected with ransomware that has encrypted their Documents folder. You need to restore the files from a previous version that was saved by File History. Where do you access the 'Previous Versions' feature to restore these files?

Accepted Answer

File Explorer > Properties > Previous Versions tab. The 'Previous Versions' tab is accessible via File Explorer by right-clicking a file or folder, selecting Properties, and then clicking the Previous Versions tab. This tab lists shadow copies or File History backups of the selected item, allowing you to restore an earlier version. In this scenario, since File History was enabled, the previous versions of the Documents folder will appear here for restoration.

Answer

Control Panel > File History > Restore personal files

Answer

Settings > Update & Security > Backup

Answer

Computer Management > Storage > Disk Management

Question 15

A technician is removing malware from a Windows 10 PC and wants to ensure that no remnants remain in the registry or startup folders. After running an antivirus scan and deleting infected files, which additional step should the technician perform?

Accepted Answer

Check and clean startup entries using MSConfig or Autoruns.. After removing malware, it is critical to check and clean startup entries using tools like MSConfig or Autoruns to prevent the malware from reloading on reboot. Malware often adds entries to the registry Run keys or the Startup folder to persist. Simply deleting files may leave these entries intact, allowing the malware to reinstall itself.

Answer

Run the Windows Memory Diagnostic tool.

Answer

Disable System Restore to free up disk space.

Answer

Update all device drivers to the latest versions.
