Question #243
A user reports being unable to access the network. A help desk technician notices an APIPA on the user’s workstation.
Which of the following services should the technician investigate first?
- A . RADIUS
- B . DHCP
- C . AAA
- D . DNS
Correct Answer: B
B
Explanation:
DHCP (Dynamic Host Configuration Protocol) is a network service that automatically assigns IP addresses and other configuration parameters to devices that request them. DHCP simplifies the management of IP addresses and avoids conflicts and errors67. An APIPA (Automatic Private IP Addressing) is a feature of Windows that assigns a default IP address in the range of 169.254.x.x to a device when it cannot obtain a valid IP address from a DHCP server. An APIPA indicates that there is a problem with the DHCP service or the network connectivity between the device and the DHCP server89. Therefore, the technician should investigate the DHCP service first to check if it is running, configured correctly, and has enough available IP addresses to assign. The other services are not directly related to the IP address assignment. RADIUS (Remote Authentication Dial-In User Service) is a protocol that provides centralized authentication, authorization, and accounting for network access10. AAA (Authentication, Authorization, and Accounting) is a framework that controls the access and usage of network resources11. DNS (Domain Name System) is a service that resolves domain names into IP addresses12.

Question #248
A technician is troubleshooting a laptop that displays a blank screen when the user turns it on. The technician shines a flashlight into the LCD and sees a faint image.
Which of the following is the most likely cause of the issue?
- A . Defective inverter
- B . Incompatible video driver
- C . Incorrect input source
- D . Burned-out bulb
Correct Answer: A
A
Explanation:
The most likely cause of the issue is a defective inverter. An inverter is a device that converts the direct current (DC) power from the laptop battery or adapter to the alternating current (AC) power that the LCD backlight bulb needs. The backlight bulb is a fluorescent lamp that illuminates the LCD screen and makes the image visible. If the inverter is defective, it may not provide enough power to the backlight bulb, or it may stop working intermittently. This can result in a dim, dark, or blank screen, even though the LCD panel is still functioning and displaying a faint image. To troubleshoot a defective inverter, the technician can follow these steps:
Connect an external monitor to the laptop and check if the image is displayed normally. If the external monitor works fine, it means that the laptop video card and driver are not the cause of the issue.
Shine a flashlight into the LCD screen and look for a faint image. If the image is visible, it means that the LCD panel is not the cause of the issue.
Check the inverter cable and connector for any damage, loose connection, or corrosion. The inverter cable is a thin wire that runs from the laptop motherboard to the inverter board, which is usually located at the bottom of the LCD screen. The inverter connector is a small plug that connects the inverter cable to the inverter board. The technician can try to reseat the inverter cable and connector, or replace them if they are faulty.
Check the inverter board for any damage, burn marks, or blown fuses. The inverter board is a small circuit board that contains the inverter and other components. The technician can try to test the inverter board with a multimeter, or replace it if it is defective.
