A+ 220-1102 — Domain 3: Software Troubleshooting

About this course

This practice-test pack targets Domain 3: Software Troubleshooting on the 220-1102. You’ll drill realistic scenarios covering Windows boot failures, BSODs, slow systems, services and startup conflicts, app crashes, patch/update problems, printer and spooler errors, browser/email glitches, profile and permission issues, and malware cleanup. You’ll also handle macOS and Linux basics (updates, package managers, permissions, logs), plus mobile OS issues (iOS/Android app errors, storage/battery/network problems) and cloud/app sync hiccups.Each question uses the CompTIA troubleshooting model—identify the problem, establish a theory, test, create/implement a plan, verify full functionality, and document. Every option (even wrong answers) includes an explanation, so you learn why a distractor is unsafe or irrelevant.You’re only buying tests here—no long lectures. Use 15-minute study bursts: do 10–15 questions, read every explanation, flag weak areas, and return tomorrow. The cumulative effect of short, consistent sessions beats cramming: your pattern-recognition improves, and fixes become second nature. Repeat until you can explain the right answer before revealing it. When you can predict the distractors, you’re exam-ready.Practice test lineup (Domain 3)Test 1 — Windows Application & OS IssuesApp crashes, update failures, profile/permission errors, missing DLLs, app compatibility, and restore/rollback choices.Test 2 — Boot, BSOD & System RecoveryBoot loops, recovery media, WinRE tools, Startup Repair, BCD fixes, restore points, DISM/SFC, and driver rollbacks.Test 3 — Performance, Services & Startup ConflictsSlow systems, high CPU/RAM/disk, service dependencies, startup impact, Task Manager/Autoruns, and schedu
