Introduction*
This assessment is designed to evaluate comprehensive knowledge and practical skills required for the
CompTIA A+ certification, the industry standard for entry-level IT professionals. The exam tests your ability to
install, configure, and troubleshoot end-user devices, networks, and operating systems while applying security
best practices. Questions include multiple-choice formats and scenario-based problems that emphasize real-
world application, critical thinking, and professional decision-making in IT support environments. Success
requires understanding both foundational theory and applied technical competencies across hardware,
software, networking, and operational procedures.*
Section One: Questions 1–100
Question 1
A user reports that their laptop cannot connect to the wireless network, but other devices in the same office
connect without issues. The laptop's wireless adapter shows it is enabled, but no networks appear in the
available networks list. Which of the following should the technician check FIRST?
A. Update the wireless adapter drivers
B. Check if the wireless hardware switch is turned on
C. Restart the wireless router
D. Reinstall the operating system
🟢 B. Check if the wireless hardware switch is turned on
, 🔴 RATIONALE: When no wireless networks appear at all, the most common cause is that the wireless adapter
is physically disabled via a hardware switch or function key. This is the first step in the troubleshooting
methodology—verify the simplest and most likely cause before proceeding to more complex solutions like driver
updates or OS reinstallation.
Question 2
Which of the following RAID levels provides fault tolerance with the minimum number of two drives and offers
striping with parity?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
🟢 B. RAID 1
🔴 RATIONALE: RAID 1 (mirroring) requires a minimum of two drives and provides fault tolerance by creating
an exact copy of data on both drives. RAID 0 offers no fault tolerance, RAID 5 requires a minimum of three
drives, and RAID 10 requires a minimum of four drives.
Question 3
A help desk technician receives a call from a user who cannot access any websites. The technician asks the user
to ping 127.0.0.1, which succeeds. The user then pings their default gateway successfully but cannot ping
8.8.8.8. Which of the following is the MOST likely cause?
