CompTIA A+ Certification Exam: Core 1 Sample Questions (Q445-Q450):

NEW QUESTION # 445
A user is having an issue with the touch screen on a mobile device. When the user touches the screen, the intended target is not selected. Which of the following would be the BEST action for a technician to take to resolve the issue?

  • A. Calibrate the touch screen
  • B. Update the mobile device.
  • C. Reset the mobile device
  • D. Replace the LED screen.

Answer: A

Explanation:
Calibrating the touch screen is the best action to resolve the issue of inaccurate touch input.
Calibration adjusts the touch screen's sensitivity and alignment to match the user's touch.
Resetting the mobile device could erase user data and settings and may not fix the touch screen issue. Replacing the LED screen or updating the mobile device are unnecessary and costly actions that may not solve the problem.


NEW QUESTION # 446
A technician replaced a failed PSU on a high-end workstation PC. Now, the PC fails to POST and does not stay turned on for more than five seconds. Which of the following power connections was most likely forgotten during installation?

  • A. 12V
  • B. 5V
  • C. 120V
  • D. 220V

Answer: A

Explanation:
The issue described suggests the 12V CPU power connector was likely forgotten during installation. The
12V power rail is essential for the operation of high-end workstation components, including the CPU.
Without the 12V connection, the system will fail to POST and may power off shortly after being turned on.
* Why 12V?
* The 12V connector is critical for providing power to the CPU via the motherboard. Modern CPUs require a dedicated power source from the PSU, usually supplied through the 4-pin or 8- pin EPS12V connector.
* If this connection is omitted, the motherboard will not receive adequate power for the CPU to function, resulting in the system failing to POST or shutting down after a brief period.
* Incorrect Options:
* A. 5V: The 5V rail powers USB devices, some motherboard components, and certain peripherals, but not the CPU directly.
* C. 120V and D. 220V: These voltages refer to the power supply's input from the wall outlet, not the internal connections to components.
CompTIA A+ Exam Objectives References:
* 220-1101 (Core 1), Section 3.5: Explains power supply requirements and troubleshooting scenarios related to component connections.

  • B. GPS
  • C. Wi-Fi extender
  • D. Bluetooth

Answer: A

Explanation:
Explanation
A cellular card is a device that allows a laptop to connect to the internet using a cellular network, such as 4G or 5G. A cellular card can provide internet access when the user travels and does not have access to a Wi-Fi network. A cellular card may require a subscription plan from a cellular service provider. A Wi-Fi extender is a device that boosts the signal of an existing Wi-Fi network, but it does not provide internet access by itself.
Bluetooth is a wireless technology that allows devices to communicate over short distances, but it does not provide internet access either. GPS is a satellite-based system that provides location and navigation information, but it does not provide internet access as well. References:
