What the CompTIA Network+ N10-009 is and who it is for
The CompTIA Network+ is the vendor neutral standard certification for networking fundamentals. It validates that you can establish, maintain, troubleshoot and secure wired and wireless networks across enterprise environments, covering networking concepts, implementation, operations, security and troubleshooting. It is DoD 8140 approved and it is the recognised baseline credential for network administrator, NOC technician and network support specialist roles. The current version is V9, exam code N10-009, which launched on 20 June 2024.
CompTIA recommends CompTIA A+ plus 9 to 12 months of hands on networking experience. In practice the exam suits help desk and support staff moving into network roles, junior administrators who want a recognised credential, and anyone heading for Security+ or a vendor networking track who wants the fundamentals confirmed first.

What is on the exam
Five domains with a fairly even spread. Troubleshooting is the largest, and networking concepts is a close second.
Networking concepts (23%). The theory: the OSI model, networking appliances and their functions, cloud concepts, common ports and protocols, IP addressing and subnetting, and modern network environments. This is where most candidates start and where many spend too long.
Network implementation (20%). Putting the theory into place: routing technologies, switching features such as VLANs, wireless configuration and physical installation factors. Questions ask you to choose the right technology or setting for a described requirement.
Network operations (19%). Keeping a network running: documentation, monitoring, network management protocols, disaster recovery concepts and the operational processes around change and configuration.
Network security (14%). The smallest domain: security concepts and terminology, common attack types, and the network hardening and access control features that defend against them. Small, but a domain candidates often leave until last and then skip.
Network troubleshooting (24%). The largest domain. A troubleshooting methodology, then cabling, physical interface, network service, performance and wireless problems, and the tools you use to diagnose them. Performance based questions here give you a scenario and expect you to find the fault.
Why people fail it
Candidates fail the Network+ not because they do not know networking, but because the exam tests five demanding domains across 90 minutes and includes performance based questions that require you to troubleshoot and configure, not just recognise a correct answer. Up to 90 questions in 90 minutes is an average of one minute each, and a PBQ that asks you to configure or diagnose something can take several times that.
The N10-009 is also broader than most candidates expect. Networking concepts, implementation, operations, security and troubleshooting are all tested, and troubleshooting alone is worth 24%. The classic mistake is to spend the study time on subnetting and the OSI model, which feel like the heart of networking, and skip the operations and security domains, which together are 33% of the exam. Candidates who do that walk out surprised.
The last cause is unfamiliarity with the format. CompTIA questions describe a symptom or a requirement and ask for the best answer among options that are all plausible. If the first time you meet that style is in the exam room, you spend your minute per question working out what is being asked rather than answering it. Practice questions with explanations fix that, and the explanations of the wrong options matter as much as the right one.
A study plan that fits the exam
Six weeks, with time split by domain weight. Concepts and troubleshooting get the most, security the least, and nothing gets skipped.
- Week 1: networking concepts. The OSI model, ports and protocols, appliances and IP addressing. Do subnetting until it is quick, then stop: it is one part of a 23% domain, not the whole exam. Try the free Network+ practice questions at the end of the week.
- Week 2: concepts finish, implementation begins. Cloud and modern network concepts in the first half, then routing and switching technologies.
- Week 3: implementation finishes, operations begins. Wireless and physical installation, then documentation, monitoring and management protocols. Start working the questions in the N10-009 practice question pack by domain, reading every explanation.
- Week 4: operations finishes, network security. Disaster recovery and operational processes, then the full security domain: concepts, attack types, hardening and access control. It is 14% and it is the domain most often skipped.
- Week 5: network troubleshooting. A full week on the largest domain. Learn the methodology, then work through cabling, interface, service, performance and wireless faults with the diagnostic tools for each. Do the troubleshooting PBQs in the pack more than once.
- Week 6: timed runs. Use the questions only PDF for full sittings against the 90 minute limit, score by domain, and spend the rest of the week on the weakest one.
On exam day
You sit N10-009 at a Pearson VUE testing centre or online with a proctor. If you are testing online, check the room, desk and webcam rules on the vendor page and run the system check on your own computer before the day. At a centre, bring the identification your booking confirmation asks for and arrive early.
The clock is the main thing to manage: up to 90 questions, including PBQs, in 90 minutes. Work through the multiple choice items at a steady pace, and if a PBQ is going to eat a large block of time, flag it if the interface allows and come back to it with the time you have saved. The passing score is 720 on a scale of 900, and the scale is not a straight percentage, so do not try to count your marks during the exam. Answer everything and keep moving.
Frequently asked questions
How many questions are on the N10-009 and how long do I get?
Up to 90 questions, including performance based questions, in 90 minutes. The passing score is 720 on a scale of 900 and the exam fee is US$399 per voucher.
What happens if I fail? Can I retake it?
You can retake it, but each attempt needs a new voucher at the full exam fee, currently US$399. CompTIA publishes its retake policy, including any waiting period between attempts, on its website, so check the current rules before you rebook. The practice pack is refunded if you fail and the voucher is not, which is the best reason to do your timed practice before the first attempt rather than after it.
Is the practice question pack enough on its own?
No. It is 769 practice questions, MCQs and PBQs, with an explanation for every answer and every wrong option, mapped to the N10-009 objectives. That makes it a good way to learn the question format and find your gaps, but it is practice, not a course. You still need a source for the material itself, whether that is a study guide, a video course, the official objectives or hands on time with real equipment. Use the pack to test yourself and steer your study.
Do I need A+ before Network+?
CompTIA lists A+ plus 9 to 12 months of hands on networking experience as recommended experience, not as a requirement. If you already work with networks and know the fundamentals, you can book Network+ directly. If you are new to IT, starting with A+ gives you the hardware and networking basics that Network+ builds on.
