Welcome to the Hardware & Network Troubleshooting practice page for the CompTIA A+ (220-1101 / 220-1102) exam. This drill is published by ExamEdge Prep against the official CompTIA blueprint and covers the Hardware & Network Troubleshooting knowledge area in detail.

The exam runs 90 questions / 90 min per core and requires 675 / 900 (1101), 700 / 900 (1102) to pass. Most candidates report needing 60–120 hours of focused review across the entire blueprint; this page contributes roughly five to seven percent of that prep time. Working the Hardware & Network Troubleshooting objectives in isolation is the proven approach used by veteran tutors — CompTIA A+ questions in this knowledge area mix recognition (definitions, components, classifications) with applied scenarios that require you to weigh competing options under realistic time pressure. If you are pairing this drill with a textbook or LMS, log your incorrect answers in a single-row spreadsheet so the patterns surface after two or three sittings.

What’s tested in Hardware & Network Troubleshooting

The Hardware & Network Troubleshooting domain on the CompTIA A+ carries one of the heaviest weightings on the published blueprint. Expect to see questions that test (1) terminology and core definitions, (2) procedural sequencing — what to do first, second, and last in a multi-step process — and (3) judgment calls where two answer choices look defensible but only one is the best answer for the role being tested. The CompTIA emphasizes scenario-based items that simulate the day-to-day decisions of a credentialed practitioner; rote memorization will not be enough above the cut score.

Common pitfalls candidates fall into on this section include misreading qualifiers ("always," "never," "first," "primarily"), assuming generic best practice instead of the practice the exam blueprint specifically endorses, and burning time on items they should flag and return to. The questions on this page have been written with those traps embedded so you can see them coming on test day.

How to use this Hardware & Network Troubleshooting practice set

Work each question without looking at the explanation. Mark the items you are unsure of even when you guess correctly — those are the high-leverage ones to study. After submitting, review every explanation, even on the items you got right; the rationale often introduces an exam-relevant nuance that will appear on a future drill in this series. Then move on to the next variant in the Hardware & Network Troubleshooting sequence and repeat with a 24-hour gap so spaced repetition can do its work.

The investment to credential, including the CompTIA A+ exam fee, is non-trivial. Most candidates spend $253 USD per core plus study materials, application fees, fingerprinting, background checks, and the opportunity cost of study time. A retake doubles the financial cost and adds 30–90 days of delay before you can sit again. The honest payoff for thirty extra hours of high-quality drill is a first-attempt pass; this page is a piece of that thirty hours.

Recommended next steps

After completing this practice variant, move to a different domain on the same exam to build breadth, then return to Hardware & Network Troubleshooting the following day for retention. The full exam outline for the CompTIA A+ credential is published by CompTIA; you can download the candidate handbook directly from the agency. ExamEdge Prep tracks the published outline and updates these drills whenever the blueprint changes — typically every 36 months for IT certifications and every five to seven years for state licensing exams.
