CompTIA A+ Core 1 (220-1201) Overview — Format, What’s Tested & How to Prepare

Everything to know before taking CompTIA A+ Core 1 (220-1201): format and timing, who it’s for, skills measured by domain, and a compact study plan mapped to our syllabus and practice.

Exam snapshot

  • Certification: CompTIA A+ — Core 1 (220-1201)
  • Audience: Help desk/desktop support, field techs, entry-level IT roles, career-switchers, students
  • Experience target: 6–12 months hands-on or equivalent labs/projects
  • Format: Multiple-choice (single/multi), a few performance-based questions (PBQs)
  • Timing / count: Varies by form; plan adequate time for check-in and review
  • Credential requirement: You must pass Core 1 (220-1201) and Core 2 (220-1202)

Study funnel: Read this Overview → work the Syllabus objective-by-objective → keep the Cheatsheet open for last-mile recall → validate with Practice.


What Core 1 (220-1201) measures

1) Hardware & devices

  • PC components (motherboard, CPU, RAM, PSU), storage (HDD/SSD, SATA, M.2/NVMe)
  • Peripherals & connectors (USB generations, display standards, Thunderbolt)
  • Printers (laser process order; common faults), SOHO devices

2) Mobile devices

  • Laptops, tablets, phones; batteries, displays, ports; accessories (Bluetooth, NFC)
  • Mobile networking (hotspot, tethering), MDM basics and profiles (awareness)

3) Networking (SOHO focus)

  • Ports & protocols, IP basics (DHCP, DNS, APIPA), Wi-Fi standards/security
  • Cabling (Cat5e/6/6a, fiber LC/SC), SOHO router setup, VLAN/WPA2/3 practices

4) Virtualization & cloud (client depth)

  • Type 1/Type 2 hypervisors; VM resources; snapshots vs backups
  • Client cloud usage: storage sync, thin clients, VDI awareness

5) Troubleshooting

  • Structured methodology (identify → theory → test → fix → verify → document)
  • Safety/ESD; tool pickers (multimeter, cable tester, CLI diagnostics)

Who should take Core 1?

  • New or early-career IT professionals targeting help desk/desktop support roles
  • Career-switchers building hands-on confidence with hardware/networking basics
  • Students in IT programs seeking an industry baseline credential

Readiness checklist

  • I can match ports to services (HTTP/HTTPS, SSH, RDP, DNS, DHCP, SMTP/IMAP/POP3).
  • I pick the right cable/connector (Cat6 vs Cat6a, LC vs SC, SATA vs M.2 NVMe).
  • I know Wi-Fi generations and WPA2/WPA3 setup at SOHO routers.
  • I can list laser printer steps in order and fix common print defects.
  • I apply the troubleshooting method and choose the least intrusive next step.

Compact 3–4 week plan

Week 1: Hardware & devices → printers → daily 20-question drills
Week 2: Networking (ports, Wi-Fi, SOHO) → mixed sets (hardware + networking)
Week 3: Mobile + virtualization/cloud → PBQ-style practice → review weak areas
Week 4: Two full mocks; convert misses into 2-bullet “rules of thumb”; light re-drills


Exam-day tactics

  • First pass fast; flag PBQs/long stems and return later.
  • If two answers seem plausible, choose the one that is safer, simpler, and reversible.
  • For networking symptoms, check IP/DHCP/DNS before cabling swaps.
  • For hardware, confirm power/thermals/seating before deep changes.
