WGU D412 PA - Help Desk Ticket Analysis: Troubleshooting
Network Issues Exam Questions with Correct Answers and
Explanations.




TICKET #1: USER UNABLE TO CONNECT TO COMPANY VPN
Scenario: A remote employee reports they cannot connect to the company VPN. They
were connected yesterday and have not changed any settings on their home network.
They are using a company-issued laptop with Windows 10. The error message states:
"VPN connection failed - authentication failed."




1 What is the most likely cause of this issue?

 A The user's internet connection is down
 B The VPN server is offline
 C The user's password has expired or was changed
 D The user's firewall is blocking the connection

Answer: C
Explanation: The error message "authentication failed" indicates an issue with credentials,
not connectivity. Since the user was connected yesterday and no settings were changed,
the most likely cause is an expired password or recent password change that hasn't been
updated in the VPN client. Internet connectivity issues would show a different error, the
VPN server being offline is less common, and firewall blocking would present differently




2 What is the first troubleshooting step the help desk should take?

, A Reinstall the VPN software
 B Reset the user's network adapter
 C Verify the user's account status in Active Directory
 D Reboot the VPN server

Answer: C
Explanation: Since the error is authentication-related, checking the user's Active Directory
account status is the logical first step to determine if the account is locked, disabled, or if
the password has expired. Reinstalling software, resetting the network adapter, or
rebooting the server would not resolve an authentication issue




3 After verifying the user's account is active, what should the technician do next?

 A Escalate to the network team
 B Have the user verify their username and password are entered correctly
 C Issue a new laptop
 D Change the user's security group

Answer: B
Explanation: The simplest solution is often the correct one. Before escalating, the
technician should have the user confirm they are entering the correct credentials. Typos or
CAPS LOCK are common issues. Escalation, issuing a new laptop, or changing security
groups would be premature




4 If the user can connect to the VPN but cannot access internal resources, what is
the most likely cause?

 A The user's internet speed is too slow
 B The VPN connection is established but the user does not have proper
permissions
 C The user's antivirus is blocking access
 D The user is using the wrong Wi-Fi network

Answer: B
Explanation: A successful VPN connection indicates the authentication and connectivity

, are working. If internal resources are inaccessible, it is likely a permissions issue (user does
not have access to specific shares or applications). Internet speed, antivirus, and Wi-Fi are
less likely to cause this specific pattern




5 The user reports they can access internal resources now, but the connection is
very slow. What should the technician check?

 A The user's CPU usage
 B The user's battery level
 C The user's internet speed and latency
 D The user's screen resolution

Answer: C
Explanation: Slow VPN performance is often due to the user's internet connection speed or
high latency. The technician should have the user run a speed test to check
download/upload speeds and ping latency. CPU usage, battery level, and screen resolution
would not typically cause slow VPN performance




6 The user is still experiencing slow VPN speeds. The technician checks the
company VPN server and finds it is at 95% capacity. What action should the
technician take?

 A Tell the user to work offline
 B Reinstall the VPN client
 C Escalate to the network team to assess VPN server capacity
 D Disable the user's VPN profile

Answer: C
Explanation: A VPN server at 95% capacity indicates a systemic issue that requires
network team escalation. The network team may need to add additional resources,
implement load balancing, or troubleshoot the server. Telling the user to work offline,
reinstalling the client, or disabling the profile are not appropriate solutions

, TICKET #2: USER UNABLE TO PRINT TO NETWORK PRINTER
Scenario: A user in the accounting department reports they cannot print to the network
printer located in their office. Other users on the same floor can print to it. The user's
computer shows the printer as "offline" in the devices and printers window. The user has
rebooted their computer twice.




7 What is the first step the help desk technician should take?

 A Reinstall the printer driver
 B Check if the printer is physically connected and powered on
 C Restart the print spooler service
 D Delete and re-add the printer

Answer: B
Explanation: The technician should first verify the printer is physically powered on and
connected to the network. Since the printer shows as "offline," the simplest physical cause
should be ruled out first. Other steps may be needed, but they come after verifying
physical connectivity




8 The printer is powered on and connected. What should the technician check
next?

 A The user's antivirus settings
 B The user's hard drive space
 C The print spooler service on the user's computer
 D The user's network cable

Answer: C
Explanation: After ruling out physical issues, the next most common cause of a printer
showing "offline" is a stopped or hung print spooler service. Restarting the print spooler
can often resolve this issue. Antivirus settings and hard drive space are less likely, and the
network cable would affect all network access, not just printing
