20+ practice questions focused on Common Networking Hardware — 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 Common Networking Hardware PracticeA company is upgrading its network to support 10 Gbps speeds for a server farm. The existing cabling is Cat6a, and the switches are Gigabit. The IT manager wants to minimize cost while achieving 10 Gbps. Which hardware change is required?
Explanation: This question tests knowledge of cabling standards and switch capabilities. Cat6a supports 10 Gbps up to 100 meters, so the cabling is sufficient. The bottleneck is the switches, which must be upgraded to 10 Gbps models. SFP+ modules can be used for fiber connections if needed, but the question focuses on copper.
A small office with 15 employees uses a single switch to connect all workstations. Users report that the network becomes extremely slow during peak hours, and some packets are being dropped. The switch is a 10/100 model with a 1 Gbps uplink to the router. What is the most likely cause of the slowdown?
Explanation: This question tests understanding of switch port speeds and network congestion. A 10/100 switch limits each workstation to 100 Mbps, which can cause bottlenecks with multiple users. Upgrading to a Gigabit switch would provide 1000 Mbps per port, alleviating the slowdown.
A user reports that their desktop computer cannot connect to the internet, but other devices on the same network work fine. You check the patch cable from the wall jack to the PC and find it is a Cat5e cable. The PC's network adapter shows a link light, but no activity. What should you do first?
Explanation: This question tests basic network troubleshooting steps. A link light indicates physical connectivity, but no activity suggests a configuration issue. Checking the IP address assignment is the logical first step before replacing hardware.
A technician is setting up a new wireless network for a warehouse. The warehouse has metal shelving and concrete walls. Which wireless standard should the technician choose to maximize range and penetration through obstacles?
Explanation: This question tests knowledge of wireless standards and their characteristics. 2.4 GHz signals (like 802.11n) have better range and penetration through obstacles than 5 GHz signals, making them ideal for environments with many barriers.
A small business has a single router with four built-in switch ports. They need to connect 12 wired devices. They have a 24-port unmanaged switch. Which configuration will provide the best network performance and connectivity?
Explanation: This question tests understanding of network topology and switch use. Connecting all devices to a single switch and then uplinking that switch to the router is the most efficient, as it keeps traffic local and uses the router only for internet access.

Start with 10 questions to gauge your current understanding of Common Networking Hardware. 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
Common Networking Hardware 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. Common Networking Hardware is tested as part of the CompTIA A+ Core 1 220-1201 blueprint. Practicing with targeted Common Networking Hardware questions ensures you can handle any format or difficulty that appears.
