A+ 220-1101 — Domain 5: Hardware & Network Troubleshooting

About this course

Tackle the toughest break/fix tickets with a clear, repeatable playbook. This course zeroes in on CompTIA A+ 220-1101 Domain 5 (Hardware & Network Troubleshooting) and turns exam objectives into real-world skills. You’ll practice isolating faults, confirming the fix, and documenting results across PCs, peripherals, printers, mobile devices, and wired/wireless networks. We start with the CompTIA troubleshooting methodology—identify, hypothesize, test, plan, verify, document—then apply it to common symptoms: POST failures, overheating, RAM and storage issues, boot errors, display glitches, printer jams/ghosting, mobile app/policy conflicts, DHCP/DNS problems, IP conflicts, Wi-Fi interference, VLAN/duplex mismatches, and more. Along the way you’ll use the right tools (multimeter, loopback plug, cable tester, ipconfig/ping/tracert) and safety practices (ESD, power, data handling).Expect practice-driven learning: scenario questions with detailed explanations, quick-reference steps for triage, and checklists you can adapt to your workflow. By the end, you’ll be able to troubleshoot systematically, minimize downtime, and communicate fixes like a pro—skills that help on the A+ exam and at the help desk.This course is tests-only: no lectures, just targeted practice. Use 15-minute study bursts daily—review mistakes, tag weak topics, and retest. Spaced, cumulative practice compounds quickly, building retention and speed while keeping motivation high. Small, consistent sessions beat occasional cramming everywhere.DisclaimerCompTIA A+ is a registered trademark of CompTIA. This course is not endorsed by or affiliated with CompTIA.
