    • Mobile Devices (13%)
    • Networking (23%)
    • Hardware (25%)
    • Virtualization & Cloud Computing (11%)
    • Hardware & Network Troubleshooting (28%)
  • Core 2 (220-1202) domains (V15)
    • Operating Systems (28%)
    • Security (28%)
    • Software Troubleshooting (23%)
    • Operational Procedures (21%)

III. Exam Details

For each exam (Core 1 and Core 2): Up to 90 questions. Question styles include multiple choice, drag-and-drop, and performance-based questions (PBQs).

Passing scores: Core 1 = 675/900, Core 2 = 700/900

V. Hands-On Labs

  • Core 1-leaning labs
    • Build or refurb a PC: RAM/storage swaps, BIOS/UEFI settings, boot issues
    • Practice connector/cable identification (USB standards, video, storage)
    • Home networking: set up a SOHO router, Wi-Fi security, DHCP vs static IP, basic port knowledge
    • Virtualization: install VirtualBox/VMware Player, create a Windows + Linux VM, snapshot/rollback
  • Core 2-leaning labs
    • OS installs: Windows clean install + drivers, updates, user accounts, permissions
    • Command line basics: file operations, networking checks, process/service tools
    • Security basics: MFA, password policies, encryption concepts, malware cleanup flow
    • Ticketing mindset: write “problem / environment / steps tried / fix / prevention” notes for everything you break & repair

VI. Renewal

CompTIA A+ is in the Continuing Education (CE) program: it typically renews on a three-year cycle. CompTIA lists CE fees for A+ as $75 total for the three-year renewal period.

VII. What to Do After A+

Common next steps after A+:

  • COMPTIA Network+ (strong follow-up if you want IT infrastructure skills)
  • COMPTIA Security+ (great if you want to lean toward security roles)
