CompTIA's Network+ cert has a roughly 75% first-attempt pass rate among candidates who use structured study materials — but the 25% who fail mostly share the same problem: they treated it like a vocabulary quiz instead of a practical troubleshooting exam. The N10-009 version (current as of 2024) is heavier on network operations and security concepts than its predecessors, and candidates who underestimate that shift tend to find out the hard way during the performance-based questions.
This guide covers what the Network+ cert actually tests, who should pursue it, a realistic study path, and the courses worth spending money on — with no filler.
What the Network+ Cert Actually Covers
The exam is split across five domains. Knowing the weight of each one should directly shape how you allocate your study time:
- Networking Concepts (23%): OSI model, TCP/IP stack, common ports/protocols, routing concepts, and cloud networking basics. This is the foundation everything else builds on.
- Network Implementation (19%): Switching, VLANs, wireless standards (802.11ax, WPA3), and physical infrastructure — cabling, transceivers, patch panels.
- Network Operations (17%): Monitoring tools, network documentation, disaster recovery, and change management. This domain trips up self-taught candidates who have hands-on skills but no exposure to enterprise operations processes.
- Network Security (20%): Common attack types, network hardening, firewalls, IDS/IPS, and VPNs. The weighting here has increased in recent exam versions.
- Network Troubleshooting (21%): The domain that separates memorizers from practitioners. Performance-based questions ask you to interpret outputs, diagnose connectivity issues, and work through methodology — not just name the seven OSI layers.
The exam is 90 minutes, up to 90 questions (multiple choice and performance-based), and requires a score of 720 out of 900 to pass. Performance-based questions (PBQs) appear early in the exam — completing them first, even partially, before moving to multiple choice is a widely recommended strategy.
Is the Network+ Cert Worth It?
The honest answer: it depends on where you are in your career, not on the certification itself.
For someone coming in with zero IT experience, Network+ is a solid credential — it's vendor-neutral, DoD 8570 approved (meaning it satisfies baseline requirements for many government contractor roles), and recognized broadly enough that hiring managers in IT support, help desk, and junior network roles know what it means. If you're transitioning from outside IT and want a credential that proves you understand networking beyond Wikipedia-level knowledge, Network+ delivers that signal.
For someone already working in networking — say, two or three years into a network analyst role — the calculus changes. At that point, vendor-specific certs like CCNA carry more weight with technical hiring managers, and the time investment in Network+ might be better redirected. That said, if your employer pays for it or you're moving into a role that checks the DoD 8570 box, it's a straightforward win.
Salary data from CompTIA's own research puts Network+-certified professionals at a median around $80,000-$90,000 annually in the US — but that range reflects a wide spread of roles, from entry-level help desk to junior network admin. The cert gets you in the door; experience determines where you land within that range.
How to Structure Your Network+ Cert Study
Most candidates who pass on the first attempt use a three-phase approach:
- Build the conceptual foundation. Before worrying about practice exams, get the core frameworks solid — OSI, TCP/IP, subnetting, and routing basics. Subnetting in particular is something you need to be able to do quickly and accurately under pressure. If you're slow at it, it will cost you time on the real exam.
- Work through domain-specific material. Don't study linearly from chapter one to chapter fifteen. Weight your time toward the higher-percentage domains: Networking Concepts (23%), Troubleshooting (21%), and Security (20%) together represent nearly two-thirds of the exam.
- Grind practice questions, but simulate exam conditions. The value of practice questions isn't just getting answers right — it's identifying which domains you're weak on and adjusting. Take at least two full-length timed mock exams before the real thing. If you're consistently scoring below 75% on practice tests, you're not ready regardless of how many hours you've put in.
Most candidates need 60-80 hours of structured study to be ready. Candidates with prior IT experience (A+, networking exposure, help desk work) can often do it in 40-50 hours. Candidates coming in cold typically need more.
Top Courses for Network+ Cert Prep
The courses below were selected based on content relevance to what the exam actually tests — not generic production quality ratings.
The Bits and Bytes of Computer Networking
This Coursera course (part of Google's IT Support certificate) is probably the most practically useful starting point for Network+ conceptual prep — it covers the OSI model, TCP/IP, DNS, DHCP, and routing in a way that maps directly to the Networking Concepts domain without getting lost in vendor-specific detail. Rating: 9.7/10.
Networking in Google Cloud: Fundamentals
Cloud networking now appears in the Network+ exam's Networking Concepts domain, and this Coursera course covers VPC architecture, subnets, and firewall rules in a hands-on way that reinforces the underlying concepts — useful for candidates who need to bridge the gap between traditional networking theory and how modern infrastructure actually works. Rating: 9.7/10.
Networking in Google Cloud: Routing and Addressing
Routing and IP addressing are core to multiple Network+ domains, and this course goes deeper on those topics than most general networking courses — particularly useful for candidates who find subnetting and routing protocols to be their weak spots. Rating: 9.7/10.
AWS SAA-C03 Practice: 850+ Questions on Networking
This Udemy practice bank is technically aimed at AWS certification candidates, but the networking questions — covering VPCs, subnetting, routing, security groups — are useful for reinforcing IP addressing and network security concepts that overlap significantly with Network+ content. Best used as supplementary practice, not a primary study resource. Rating: 9.6/10.
Network+ Cert FAQ
How hard is the Network+ cert exam?
Harder than A+, easier than CCNA. The performance-based questions are where most candidates lose points — they require you to apply troubleshooting methodology and interpret diagnostic output, not just recall definitions. If you can consistently score 78%+ on practice tests that include simulation-style questions, you're in a good position.
How long does it take to prepare for the Network+ cert?
Expect 60-80 hours of structured study if you're starting from scratch. If you already have A+ or equivalent IT experience, 40-50 hours is realistic. There's no substitute for working through practice questions in exam conditions — watching videos alone isn't enough for the troubleshooting domain.
Does the Network+ cert expire?
Yes. CompTIA certifications are valid for three years. You can renew through continuing education (earning CEUs via courses, training, or other activities) or by passing a current exam. CompTIA's CertMaster continuing education platform counts toward renewal, as do many third-party courses.
Is Network+ better than CCNA for getting a job?
For entry-level roles, especially government contractor positions or generalist IT support roles, Network+ is often the more useful credential because it's explicitly required (DoD 8570) and vendor-neutral. For networking-specific roles at enterprises using Cisco infrastructure, CCNA will open more doors. Many practitioners pursue Network+ first, then CCNA — they cover overlapping material, so the sequencing makes sense.
What's the difference between Network+ N10-008 and N10-009?
N10-009 (the current version) added more content around cloud networking, zero-trust architecture, and SD-WAN compared to N10-008. The Troubleshooting domain also received updated content to reflect modern network operations practices. If you have N10-008 study materials, they're still largely usable, but check CompTIA's published exam objectives for the gaps before your exam date.
Can you self-study for the Network+ cert without instructor-led training?
Yes — most candidates who pass do it through self-study. A combination of a good video course, the official CompTIA study guide (or Professor Messer's free materials), and a practice question bank is sufficient. Instructor-led training is useful if you're struggling with specific domains or need the structure, but it's not required.
Bottom Line
The Network+ cert is a legitimate credential for anyone entering the networking or IT infrastructure field, particularly for roles with government or defense contractors where it satisfies baseline requirements. It's also a sound precursor to CCNA if you're building toward a networking-focused career path — the conceptual overlap means your study time does double duty.
Where candidates go wrong is treating it as a memorization exercise. The troubleshooting domain and performance-based questions are designed to filter out people who can recite protocol names but can't work through a real problem. Structure your study around the five exam domains weighted by their percentage, prioritize practice exams with simulation questions, and don't book your exam date until you're consistently hitting 75-80% on timed practice tests.
Start with The Bits and Bytes of Computer Networking to get the conceptual foundation right, supplement with routing and addressing material where you're weak, and use practice question banks to close the gap. That's the path most people who pass on the first attempt actually follow.
