CompTIA Network+ (N10-009): The Complete Guide
Network+ is the vendor-neutral networking certification that IT professionals use as a foundation for almost everything that follows — cybersecurity, cloud, and infrastructure roles all assume you understand how networks work. This guide gathers the current exam facts, walks through what each domain expects, and points you toward focused resources for the parts candidates find hardest (subnetting, we're looking at you). The linked articles go deeper; this is the map.
Network+ sits in the core of CompTIA's pathway, typically taken after A+ and before Security+. It proves you can design, configure, manage, secure, and troubleshoot wired and wireless networks across on-premises, cloud, and hybrid environments.
What Network+ validates
Network+ confirms job-ready networking skills. A successful candidate can explain core networking concepts (the OSI model, IP addressing, routing and switching, ports and protocols), implement wired and wireless networks, operate and monitor networks, apply security fundamentals, and troubleshoot systematically using a defined methodology.
The emphasis is practical. The exam expects you to apply knowledge — subnet accurately under time pressure, interpret scenarios, and work through performance-based tasks — not just recognize definitions.
The current exam at a glance
The current version is N10-009, marketed as V9. It launched on June 20, 2024, replacing N10-008 (the English version of which retired in December 2024). The refresh added modern topics like SD-WAN, zero trust, SASE/SSE, infrastructure as code, VXLAN, and expanded Wi-Fi 6/6E coverage.

| Number of questions | Up to 90 |
| Question types | Multiple-choice and performance-based (PBQs) |
| Length | 90 minutes |
| Passing score | 720 on a 100–900 scale |

| Validity | 3 years, renewable via continuing education |

The five domains and their weights
N10-009 is organized into five domains. In this version, troubleshooting and networking concepts carry the most weight, while security is a smaller slice than in older versions.
- Networking Concepts — 23%. OSI model, IP addressing, ports and protocols, cloud concepts, and the fundamentals everything builds on.
- Network Implementation — 20%. Configuring routing and switching, wireless, and physical installations.
- Network Operations — 19%. Monitoring, documentation, change management, and disaster recovery.
- Network Security — 14%. Core security concepts, common attacks, and defensive techniques.
- Network Troubleshooting — 24%. The heaviest domain: applying a systematic methodology and the right tools to real problems.
We break all five down objective by objective in the domains guide.
Do you need A+ first?
No certification is required to register for Network+. That said, CompTIA recommends coming in with A+ level knowledge and 9–12 months of hands-on experience in a junior network administrator or support role. If you have under six months of experience, A+ first is a sensible move; if you already work with networks, you can go straight to Network+.

Coming from N10-008?
If you studied the previous version, the good news is that the core fundamentals — subnetting, the OSI model, routing protocols, and troubleshooting methodology — haven't changed. N10-009 mostly adds modern context: cloud and hybrid environments, SDN and SD-WAN, zero trust and SASE, infrastructure as code, and updated wireless standards. The practical takeaway is simple: study N10-009-specific materials, because older N10-008 resources no longer match the current blueprint.
How to prepare
Network+ rewards a blend of structured learning, relentless subnetting practice, and hands-on labs. Reading alone won't carry you through the PBQs or the timed subnetting questions.
- Follow a structured schedule. See the Network+ study plan.
- Build hands-on and subnetting fluency. The PBQ and hands-on prep guide covers labs, tools, and subnetting drills.
- Choose materials deliberately. Our study resources overview compares the official study guide, Labs, and Practice.
Careers and the pathway
Network+ maps to real roles: network administrator, network technician, NOC technician, systems administrator, help desk (tier 2), and network support specialist. It's recognized within workforce frameworks including DoD 8140, and it's a common prerequisite-in-spirit for security and cloud careers. We dig into roles and the pathway in is Network+ worth it.
Keeping the certification current
Network+ is valid for three years. You renew through CompTIA's continuing education program — earning continuing education units or a higher-level certification — rather than retaking the exam. Earning Security+ later, for example, can renew your Network+ automatically.
Getting started
The official self-paced course covers every objective in order and is a solid backbone for your preparation.
Start here: CompTIA Network+ CertMaster Learn (N10-009). To turn reading into skill, add the hands-on CertMaster Labs (N10-009) — or prefer to read? The official study guide eBook covers every objective too. As an Authorized CompTIA Partner, we carry official materials only.
When you're ready to book, you can pick up an official Network+ N10-009 exam voucher to schedule at Pearson VUE — or the voucher-plus-retake bundle if you'd like a safety net.
A note on voucher eligibility: Voucher eligibility depends on your exam testing location, per CompTIA policy. Testing in an emerging-market region? We don't sell those here — contact us.
FAQ
What's the difference between N10-009 and V9? They're the same thing. N10-009 is the official exam code; V9 is the shorthand for this ninth version of Network+.
Is N10-008 still available? No. The English N10-008 retired in December 2024. N10-009 is the current version.
How many questions, and how long? Up to 90 questions in 90 minutes, mixing multiple-choice with performance-based questions.
What score do I need to pass? 720 on a scaled range of 100 to 900 — weighted by question difficulty, not a straight percentage.
Do I have to take A+ first? It's recommended, not required. A+ plus 9–12 months of hands-on experience is the suggested starting point.
How long is the certification valid? Three years, renewable through continuing education units or a higher-level certification.
