A+ Core 1

This course contains the use of artificial intelligence.

Knowing a component's name is only the beginning. Can you choose a compatible replacement, separate a wireless problem from an addressing problem, or decide what to check before risking a customer's data?

Practice those decisions for CompTIA A+ Core 1 (220-1201, V15) with 460 original questions across six tests. Each question includes a reasoned overall explanation, feedback for every answer choice and a focused review suggestion.

Build your foundation, then mix the domains

• Mobile Devices and Cloud: 60 focused questions.
• Networking: 70 focused questions.
• Hardware: 80 focused questions.
• Troubleshooting: 70 focused questions.
• Mixed Mock 1: 90 questions in 90 minutes.
• Mixed Mock 2: 90 questions in 90 minutes.

The four drills support shorter, untimed study sessions. Their timers are optional. Both mixed mocks approximate the published five-domain weights using 12 mobile, 21 networking, 22 hardware, 10 virtualization/cloud and 25 troubleshooting questions. These are author-created allocations, not an official fixed exam blueprint.

Learn from the evidence

Compare interfaces, capacity and power constraints. Trace the actual service that is failing. Use controlled substitutions to narrow a fault, and distinguish a useful next test from an unsupported diagnosis. Explanations identify why plausible alternatives fail under the question's conditions.

A practical study sequence

1. Work through the focused drills alongside the official objectives.
2. Review both incorrect answers and answers you guessed correctly.
3. Take a mixed mock with its 90-minute timer.
4. Explain the deciding condition in each missed question before trying the second mock.

The 80% practice target is a study checkpoint. CompTIA reports Core 1's passing score as 675 on a 100–900 scale; a practice percentage cannot be converted into that score.

This course uses single-answer and multiple-answer selection. The real exam has up to 90 questions and includes performance-based questions. These written scenarios do not provide interactive PBQs or replace hands-on practice. A+ certification requires both Core 1 and Core 2; this course covers Core 1 only.

This is independent preparation material, not an official CompTIA product. It contains original practice questions, not recalled or leaked exam items, and makes no pass guarantee.
