1 Introduction
This document compiles 88 questions from the CompTIA A+ Core 1 assessment, or-
ganized by domain (Mobile Devices, Networking, Hardware, Virtualization and Cloud
Computing, Hardware and Network Troubleshooting). Each question includes the cor-
rect answer(s) and a reason for the selection, designed to aid in exam preparation. The
questions reflect practical scenarios and core concepts tested in the CompTIA A+ certi-
fication.

uses smart card readers for access control.
2.2 Question 2: Mobile Device Setup
Question 1. Setup account on cell phone configuration with various sync options.
Score: 14 out of 26 correct
Reason: This question tests knowledge of mobile device management,
including MFA, synchronization options, and enterprise settings, which
are critical for secure mobile configurations.
2.3 Question 17: Mobile Device Screen Damage
Question 1. User reports a company-owned device suffered damage to the screen during
a trip. Technician notices cracks on the screen and determines touch input
is no longer recognized. What components need replacing?
