If you’re preparing for A+ Core 1, here’s your reminder:
Don’t just “study tech.”
Study the objectives.
Core 1 is structured. Predictable. Passable.
But only if you know what you’re walking into.
Here’s your complete, scannable breakdown of every domain and what actually deserves your attention.
1️. Mobile Devices (15%)
Covers:
- Laptop hardware & components
- Mobile device setup (Wi-Fi, email, sync)
- Accessories & connection types
- Mobile device troubleshooting
Focus on:
Laptop parts (screens, RAM, batteries, storage). Know common fixes for overheating, no power, and connectivity issues.
2. Networking (20%)
Covers:
- Ports & protocols
- Network devices (routers, switches, APs)
- IP addressing & DNS
- Wireless standards
- Basic SOHO configuration
Focus on:
Memorize common ports (HTTP, HTTPS, SSH, RDP, etc.). Understand how devices connect in small networks. Expect scenario-based questions.
3. Hardware (25%)
Covers:
- Motherboards, CPUs, RAM, PSUs
- Storage (HDD, SSD, NVMe)
- Custom PC builds
- Printers (laser, inkjet, impact)
- Cables & connectors
Focus on:
Know what each component does and when to upgrade it. Printers are heavily tested — don’t skip them.
4. Virtualization & Cloud Computing (11%)
Covers:
- SaaS, PaaS, IaaS
- Public vs. private vs. hybrid cloud
- Virtual machines & hypervisors
Focus on:
Understand service models clearly. This is a smaller section — easy points if you prepare correctly.
5. Hardware & Network Troubleshooting (29%)
Covers:
- The official troubleshooting methodology
- Boot failures
- Network connectivity issues
- Printer & hardware problems
Focus on:
Think step-by-step. Apply logic. This domain carries the most weight.
Core 1 is about understanding how devices work, connect, and fail. If you’re serious about passing, don’t study randomly. Study with structure.
If you want a clear study roadmap that walks through every objective without overwhelm, comment “ROADMAP” or message me — I’ll send you one.
