Free CompTIA Network+ N10-009 practice exams are available here, with the first set of 20 questions at no cost. Whether you are just starting your exam prep or looking to sharpen weak areas before test day, these questions give you a realistic feel for the difficulty and style of the actual N10-009 exam.
What N10-009 covers
The Network+ N10-009 exam covers five domains: Networking Concepts (23%), Network Implementation (20%), Network Operations (19%), Network Security (14%), and Network Troubleshooting (24%). The exam tests your ability to design, configure, and manage wired and wireless networks, as well as diagnose issues using tools like ping, traceroute, Wireshark, and cable testers. The 2024 version added expanded coverage of SD-WAN, infrastructure as code, and VxLAN alongside the foundational topics that have always defined the certification.
What's in these practice exams
The question sets here are built to match the style and difficulty of the real N10-009 exam, covering all five domains proportionally across 120 unique questions in six sets of 20. Topics covered across the sets include:
- IP addressing, subnetting, and IPv6 fundamentals
- Routing protocols including OSPF, BGP, and EIGRP
- VLAN configuration, trunking, STP, and port security
- Wireless standards, 802.11 security protocols, and MU-MIMO
- Network monitoring with SNMP, NetFlow, and syslog
- Firewall types, IDS and IPS, and VPN technologies
- CompTIA troubleshooting methodology and diagnostic tools
Every question includes a detailed explanation covering why the correct answer is right and why the other three options are wrong. The first set is completely free.
How to use these questions effectively
Don't just check whether you got the answer right. Read every explanation, even when you answer correctly, because the reasoning behind each option is where the real learning happens. If you miss a question, note which domain it belongs to and revisit that area before moving on to the next set.
Work through one set at a time and compare your scores across sets to track improvement. For performance-based questions on the real exam, hands-on lab practice with tools like GNS3 or Packet Tracer alongside these multiple-choice sets makes a significant difference. Aim to consistently score above 80% on practice sets before booking your exam.
