Frequently Asked Questions

What is the CompTIA Network+ certification?

CompTIA Network+ is a vendor-neutral certification that validates your ability to design, configure, manage, and troubleshoot wired and wireless networks. It's widely recognized across the IT industry and is often a stepping stone for roles like network administrator, help desk technician, and systems engineer. Unlike vendor-specific certs, Network+ covers fundamental networking skills that apply regardless of the equipment you're working with.

How many questions are on the Network+ N10-009?

The N10-009 has up to 90 questions, and you get 90 minutes to finish them. The questions are a mix of traditional multiple-choice and performance-based questions (PBQs). PBQs are basically hands-on simulations where you might configure a network device, analyze a topology, or troubleshoot connectivity - so they take a bit more time than regular questions.

What score do I need to pass the Network+?

You need a score of 720 on a scale of 100 to 900 to pass the CompTIA Network+ N10-009. That's not a straight percentage - CompTIA uses a scaled scoring model, so the difficulty of your specific set of questions factors in. Roughly speaking, most people estimate you need to answer around 75-80% of questions correctly, but don't quote us on that exact number.

How much does the Network+ cost?

The CompTIA Network+ voucher costs $369 as of 2026. That's just the price for the assessment itself - study materials, practice resources, and prep courses are separate. If you're a student, it's worth looking into CompTIA's academic pricing or your school's testing center, which sometimes offer discounted vouchers.

How long should I study for the Network+?

Most people spend about 8 to 12 weeks preparing for the Network+, studying roughly an hour or two per day. But honestly, it depends on your background. If you've got hands-on networking experience already, you might be ready in 4-6 weeks. If you're completely new to networking concepts, give yourself closer to 3-4 months. Mix up your study routine with videos, practice questions, and hands-on labs for the best results.

Should I get Network+ before Security+?

CompTIA recommends having Network+ knowledge before pursuing Security+, and for good reason. A solid chunk of Security+ material assumes you understand networking fundamentals like ports, protocols, subnetting, and network topologies. You don't technically need Network+ as a prerequisite, but most people who skip it end up struggling with the networking-heavy questions on Security+.

Does Network+ expire?

Yes, CompTIA Network+ is valid for three years from the date you pass. To renew it, you can either retake the current version of the assessment, earn a higher-level CompTIA certification (like Security+ or CySA+), or collect enough Continuing Education Units (CEUs) through training activities. CompTIA charges an annual CE fee of $50 if you go the CEU route.
