Which of the following would be used to correct a ghost image on a laser printer?
- A.
Replace the drum
- B.
Replace the fuser
- C.

A user is connecting to the Internet using a DSL modem. The user installs a new wireless router and is unable to connect remotely to their computer, using Remote Desktop. The user had no issues connecting remotely before the wireless router was installed. Which of the following is the problem?
- A.
Wireless router drivers are needed.
- B.
Port forwarding is not setup.
- C.
The wireless router is defective.
- D.
VPN is not setup correctly.
Correct Answer
B. Port forwarding is not setup.Explanation
The problem is that port forwarding is not set up on the new wireless router. Port forwarding allows incoming connections to reach a specific device or service on the local network. Without port forwarding, the router does not know which device to send the incoming Remote Desktop connection to, resulting in the inability to connect remotely. The other options (wireless router drivers needed, defective wireless router, VPN not set up correctly) do not address the specific issue of connecting remotely using Remote Desktop.Rate this question:

Which of the following network modifications should be implemented to extend the wireless network range and allow out-of-range users to share the Internet connection?
- A.
Create a new VLAN for the out-of-range users.
- B.
Add a wireless access point for the out-of-range users.
- C.
Upgrade the out-of-range users' SSID searching software.
- D.
Enable network sharing on the users' computers that are within range.
Correct Answer
B. Add a wireless access point for the out-of-range users.Explanation
To extend the wireless network range and allow out-of-range users to share the Internet connection, adding a wireless access point for the out-of-range users is the correct solution. A wireless access point acts as a bridge between the wired and wireless networks, allowing devices to connect to the network wirelessly. By adding a wireless access point in the out-of-range area, users will be able to connect to the network and share the Internet connection. This solution does not require any modifications to the VLAN, upgrading software, or enabling network sharing on computers within range.Rate this question:

The user cannot access some Internet websites, but can connect to resources inside the local network. The technician successfully uses the ping command to test the user's connectivity. Which of the following commands can the technician run NEXT to troubleshoot the issue?
- A.
Net /?
- B.
Ipconfig /flushdns
- C.
Netstat -r
- D.
Nbtstat -R
Correct Answer
B. Ipconfig /flushdnsExplanation
The technician can run the "ipconfig /flushdns" command next to troubleshoot the issue. This command clears the DNS cache on the user's computer, which can help resolve issues with accessing certain websites. By flushing the DNS cache, any outdated or incorrect DNS information will be removed, allowing the computer to obtain fresh DNS records when trying to access websites. This can potentially resolve any DNS-related issues that may be preventing the user from accessing certain Internet websites.Rate this question:

- A.
All traffic on the network must travel over port 80.

Correct Answer
C. The firewall has the ports above 1024 blocked.Explanation
The most likely cause for the connection request timing out every time is that the firewall has the ports above 1024 blocked. This means that any communication on port 1025, which is the port the application communicates on, is being blocked by the firewall. As a result, the workstation is unable to establish a connection with the application.Rate this question:

Correct Answer
A. The system is not providing enough power to the USB port.Explanation
The most likely problem is that the system is not providing enough power to the USB port. This is indicated by the fact that the light on the drive turns on, suggesting that it is receiving some power, but the system does not recognize the device. This could be due to insufficient power being supplied to the USB port, which is preventing the system from properly detecting and recognizing the external HDD.Rate this question:
