CompTIA Network+ N10-009: The Complete Exam Guide for 2026

Network+ is the credential that proves you can run any network, regardless of vendor.

CompTIA Network+ has been the benchmark vendor-neutral networking certification for over two decades. Unlike Cisco’s CCNA (which focuses on IOS and Cisco hardware) or Juniper’s JNCIA, Network+ covers core networking concepts that apply across any equipment and any environment: on-premises, cloud, hybrid, and virtualised. This universality is both its strength and its limitation — Network+ is the right starting credential for candidates who want to work as network technicians, support engineers, or junior network administrators before specialising. It is also a DoD 8570/8140 baseline requirement, meaning that federal government contractors and military IT roles often list it explicitly as a minimum qualification.

The N10-009 version of the exam, released by CompTIA in late 2024, significantly updated two areas that had lagged behind industry reality in the N10-008 version. First, network security received a dedicated domain at 20% weighting — up from 19% in N10-008 — and the content now explicitly covers zero-trust architecture, identity-based network access controls, and modern threat vectors that appear on every enterprise network. Second, cloud and virtualisation topics were woven throughout multiple domains rather than appearing as a self-contained section, reflecting how hybrid networking has become the standard rather than the exception. The restructuring means that an N10-009 candidate must understand the same core networking concepts as always, but in the context of AWS VPCs, Azure Virtual Networks, and SD-WAN overlays rather than purely physical infrastructure.

This guide covers the N10-009 exam format, all five domains in detail, how Network+ compares to the CCNA, and the ideal study path for candidates coming from a help-desk or A+ background.

Exam format and logistics

Network+ N10-009 is a maximum-90-question exam with a 90-minute time limit. Questions are a mix of multiple-choice (single and multiple correct answers) and performance-based questions (PBQs): drag-and-drop network diagrams, simulated command-line outputs to interpret, and scenario-based troubleshooting sequences. PBQs appear at the start of the exam; most candidates should budget 15–20 minutes for them and not let them consume the entire time allocation.

The exam is delivered through Pearson VUE at authorised testing centres worldwide, or via online proctored delivery from any quiet location with a webcam. CompTIA periodically offers discount vouchers through training providers and their own store; the list price is $369 but candidates who buy through academic partners or bundle with official study materials often pay $280–$320. The exam has no formal prerequisites, though CompTIA recommends at least 9–12 months of hands-on networking experience or A+ certification before attempting Network+. Candidates with no prior networking background who study only from books rather than labs consistently report higher failure rates.

Maintaining Network+ requires earning 30 Continuing Education (CE) units over the three-year validity period. Units are earned through training, conferences, webinars, or passing higher-level CompTIA exams. Earning a higher-level CompTIA cert (Security+, CASP+, CySA+) automatically renews Network+ without requiring separate CE tracking. The annual fee for the CE program is $25 USD per year, or waived with CertMaster CE completion.

The five N10-009 domains

The five domains in N10-009 are not independent silos. Troubleshooting draws on operational knowledge; security depends on implementation; implementation depends on fundamentals. The exam frequently presents scenarios that require understanding across multiple domains simultaneously — a deliberate design choice that rewards candidates who study concepts rather than memorising domain-by-domain.

Network+ vs. CCNA: which path is right?

Network+ proves you understand how networks work. CCNA proves you can configure Cisco equipment. If you want to become a network engineer, CCNA is the destination — but Network+ is a faster first step if you’re changing careers or need DoD compliance quickly.

Recommended study path for N10-009

The N10-009 exam rewards candidates who study from both a textbook resource and a lab environment. The conceptual content (OSI model, subnetting, protocols) can be learned from books and video courses; the troubleshooting domain specifically rewards candidates who have seen real command-line output and worked through actual break-fix scenarios. A realistic study plan for candidates coming from an A+ or help-desk background is 8–12 weeks at 10–15 hours per week.

Week 1–3: Cover Domain 1 (Fundamentals) completely, with heavy focus on subnetting. Subnetting is the most consistently tested quantitative skill on the exam; candidates who cannot subnet binary-to-decimal in under 2 minutes struggle with time management on exam day. Use CIDR subnetting drills daily until it is automatic. Weeks 4–6: Domains 2 and 3 (Implementation and Operations). Set up a home lab or use Packet Tracer (free with a Cisco Networking Academy account) to practise VLAN configuration, STP observation, OSPF neighbour formation, and DHCP relay configuration. Weeks 7–9: Domain 4 (Security). Review every protocol/technology pair: what it does, what it replaces, and why. Weeks 10–12: Domain 5 (Troubleshooting) and full practice exams. Time yourself strictly on practice exams — 90 questions in 90 minutes leaves no margin for uncertainty-driven time waste.
