20+ practice questions focused on CPU — one of the most tested topics on the CompTIA A+ Core 1 220-1201 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start CPU PracticeA technician is tasked with selecting a CPU for a small form factor (SFF) office PC that must run quietly and efficiently. Which CPU characteristic is most important for this build?
Explanation: In SFF builds, heat dissipation is limited, so a CPU with low TDP generates less heat, allowing for smaller, quieter cooling solutions. This tests understanding of how TDP impacts system design and noise levels.
A user complains that their computer shuts down unexpectedly after a few minutes of gaming. You check the CPU temperature and find it is 105°C. What is the most likely cause?
Explanation: High CPU temperature under load indicates a cooling problem. The most common cause is dried or improperly applied thermal paste between the CPU and heatsink. This prevents efficient heat transfer, leading to thermal throttling or shutdown.
A technician is troubleshooting a PC that fails to POST. The CPU fan spins, but there is no display output. The motherboard has a diagnostic LED that shows a CPU error. Which step should the technician take first to resolve the issue?
Explanation: A CPU error LED indicates a problem with the processor or its installation. The most common cause is improper seating or bent pins. Reseating the CPU is a logical first step before replacing components. This tests systematic troubleshooting methodology.
A customer says their PC randomly freezes and sometimes displays a blue screen error. You run diagnostics and find that the CPU passes all tests, but the system still crashes. Which component should you check next as a likely cause of CPU-related instability?
Explanation: Even if the CPU itself is functional, instability can arise from other factors. Overheating due to a failing fan can cause intermittent crashes. The CPU fan is critical for maintaining safe temperatures under load.
A technician is configuring a new PC for a user who runs multiple virtual machines. The motherboard has an AM5 socket. Which CPU feature is most important for this workload?
Explanation: Virtual machines benefit from many cores and threads because each VM can be assigned to a separate core. AMD AM5 CPUs offer high core counts, making them ideal for virtualization. This tests understanding of how CPU architecture affects specific tasks.

Practice all CPU questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of CPU. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
CPU questions on the 220-1201 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. CPU is tested as part of the CompTIA A+ Core 1 220-1201 blueprint. Practicing with targeted CPU questions ensures you can handle any format or difficulty that appears.
