EXAM QUESTIONS AND CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (MOST RECENT!!)
1. 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: This is correct because a dim screen that is still visible
usually indicates a failing backlight inverter (on older CCFL-
backlit displays) or a failed LED backlight . The function key has
no effect, suggesting a hardware failure rather than a driver or
setting issue. A cracked screen (D) would show physical damage,
not just dimness. Thus, the inverter is the most likely culprit.

,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: This is correct because 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 laptop display
interfaces. Thus, eDP is the correct interface.
3. 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
2
,B) Instant Hotspot
C) NFC pairing
D) Wi-Fi Direct
Correct Answer: B
Rationale: This is correct because 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. Thus, Instant Hotspot is
the correct Apple-specific feature.
4. A laptop keyboard has several keys that are not working.
The technician has cleaned the keyboard and updated the
drivers, 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
3
, Rationale: This is correct because 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. Thus, keyboard
replacement is the correct next step.
5. Which mobile device synchronization method uses cellular
towers to determine a device's approximate location?
A) AGPS
B) GPS
C) Wi-Fi positioning
D) Bluetooth beaconing
Correct Answer: A
Rationale: This is correct because AGPS (Assisted GPS) uses
cellular network towers to help triangulate position faster than
standard GPS, especially indoors or in urban canyons .
Traditional GPS (B) relies solely on satellite signals, which can be
slow to acquire a fix. Thus, AGPS is the correct answer.
