A user reports that their laptop screen is very dim even when
plugged into AC power. You have tried pressing the function key
to increase brightness, but it has no effect. Which of the following
is the MOST likely cause?
A) The inverter has failed
B) The backlight has failed
C) The GPU driver is corrupt
D) The LCD screen is cracked
Correct Answer: A
Rationale: A dim screen that is still visible usually indicates a
failing backlight inverter (on older CCFL-backlit displays) or a
failed LED backlight. If the function key does nothing, it suggests
a hardware failure rather than a settings issue. A cracked screen
would show physical damage, not just dimness. The inverter
1
,converts DC power to AC for CCFL backlights, and when it fails,
the backlight either doesn't work or works very dimly .
Question 2
A technician needs to replace a broken screen on a modern
ultrabook. The new screen requires a video signal and power
over a single thin cable. Which type of display interface is being
described?
A) VGA
B) eDP (embedded DisplayPort)
C) HDMI
D) DVI
Correct Answer: B
Rationale: eDP (embedded DisplayPort) is the modern standard
for internal laptop displays, carrying both high-definition video
and power through a single thin cable. LVDS was used on older
laptops. VGA, HDMI, and DVI are external display connectors,
not internal interfaces .
Question 3
2
,A user has an iPhone and an iPad. They want to share their
cellular internet connection from the iPhone to the iPad without
using a hotspot password. Which Apple-specific feature allows
this?
A) Bluetooth PAN
B) Instant Hotspot
C) NFC pairing
D) Wi-Fi Direct
Correct Answer: B
Rationale: Instant Hotspot is an Apple feature that allows a user
to share their iPhone's cellular connection with their iPad or Mac
logged into the same iCloud account without entering a
password. The hotspot appears automatically as an available
network on the iPad. Traditional tethering requires password
entry .
Question 4
A laptop keyboard has several keys that are not working. The
technician has cleaned the keyboard and updated the drivers,
3
, but the issue persists. What is the NEXT step in the
troubleshooting process?
A) Replace the entire laptop
B) Replace the keyboard
C) Reinstall the operating system
D) Use an external USB keyboard
Correct Answer: B
Rationale: After cleaning and driver updates fail, the most likely
next step is hardware replacement. Laptop keyboards are
typically replaceable components. While an external keyboard
could be a temporary workaround, the proper fix is replacing
the internal keyboard. Reinstalling the OS would not fix a
hardware issue .
Question 5
Which mobile device synchronization method uses cellular towers
to determine a device's approximate location?
A) AGPS
B) GPS
