CompTIA Network+ Practice Test (N10-009) – Complete Certification Exam Guide

What This Exam Actually Certifies

CompTIA Network+ checks whether you can do the unglamorous, essential work of keeping a network running: deploying wired and wireless infrastructure, configuring services, monitoring for problems before they become outages, and closing off the obvious security gaps. It is deliberately vendor neutral. You will not see a single Cisco IOS command or a Juniper interface on this exam. Instead you are tested on concepts and troubleshooting logic that apply whether the shop runs Cisco, Ubiquiti, Aruba, or a mixed bag of everything, which is realistically what most IT support and network admin jobs look like day to day.

The current version, N10-009, launched on June 20, 2024, replacing N10-008. It leans further into cloud networking, SD-WAN, zero trust concepts, and modern wireless standards than the previous version did, reflecting how much on-premises-only networking has shrunk as a job category.

Who This Exam Is For (and Who It Is Not For)

Network+ sits between CompTIA A+ and the vendor-specific tier (Cisco CCNA, Juniper JNCIA, and similar). It fits people who already understand basic computer hardware and operating systems and now need to prove they can handle the network layer: help desk technicians moving into network support, systems administrators who inherited network duties, and career changers coming from a non-IT background who have put in study time and maybe a home lab.

It is not the right target for someone who already manages enterprise Cisco infrastructure day to day. If that describes you, CCNA will carry more weight with hiring managers because it tests actual configuration on the platform you would be working with. Network+ is also not a substitute for hands-on experience. CompTIA is explicit that there are no formal prerequisites, but candidates who skip the recommended A+ plus 9 to 12 months of hands-on exposure tend to struggle with the performance-based questions, which assume you have actually touched a switch or a router before.

Exam Format and Structure

Ninety minutes for up to 90 questions sounds generous until the performance-based questions show up. These are not multiple choice. You get a simulated environment, a scenario, and you have to build or fix something: assign IP addresses correctly, terminate a cable diagram, or troubleshoot a broken topology by clicking through actual interface elements. They typically appear early in the exam and can eat 5 to 10 minutes each if you are not familiar with the format, which is why pacing matters more here than on a pure multiple-choice test.

The multiple-choice portion includes both single-answer and multiple-response questions, plus some drag-and-drop matching. There is no penalty for guessing, so an unanswered question is always worse than a wrong guess. CompTIA does not publish the exact split between PBQs and traditional questions, and it can shift slightly between exam forms, so treat "maximum of 90" as the ceiling rather than a fixed count you can plan around minute by minute.

Domains and Weightings

CompTIA publishes these weightings directly, and they shifted meaningfully from N10-008, where troubleshooting and security carried different emphasis.

Troubleshooting is the single largest domain, and it is not a standalone topic so much as a lens applied across the other four. Expect scenario questions that combine a networking concept (say, VLAN behavior) with a troubleshooting decision (why a device on that VLAN cannot reach a resource). Security dropped to the smallest share at 14%, but do not read that as "safe to skip." A missed security question is worth the same as a missed troubleshooting question, and the security domain covers a wide span, from PKI and RADIUS to social engineering attack types.

Cost Breakdown

The list price is $369 USD for a single exam voucher purchased directly from CompTIA, though third-party training providers and regional CompTIA storefronts sometimes price it differently based on currency and local taxes, so treat that figure as a US baseline rather than a global constant. A retake, if you do not pass, requires purchasing another full-price voucher unless you bought a bundle that included Retake Assurance up front. CompTIA and its partners frequently sell Network+ as part of a bundle with CertMaster Learn or CertMaster Practice, and those bundles can substantially discount the effective per-item cost of the voucher if you were going to buy study material anyway. If you are not going to use the bundled training, a standalone voucher is usually the cheaper path.

Prerequisites and Eligibility

There is no enforced prerequisite. CompTIA will let anyone register and sit the exam. The A+ certification and 9 to 12 months of hands-on networking experience are recommendations, not gatekeepers. In practice, candidates coming in without that background tend to underestimate how much the PBQs assume familiarity with network administration tasks, not just terminology memorized from a study guide.

How the Exam Is Scored and What Passing Requires

Network+ uses a scaled score from 100 to 900, and you need 720 to pass. This is not a simple percentage of correct answers. CompTIA weights questions based on difficulty and domain, so two candidates who get the same raw number of questions right can land on different scaled scores depending on which questions they missed. You receive your pass or fail result immediately after finishing the exam, along with a breakdown of performance by domain, which is useful information if you need to retake it and want to know where to focus.

Renewal and Continuing Education

The certification is valid for three years from the date you pass. To keep it active beyond that, CompTIA's Continuing Education (CE) program gives you a few paths: earn enough CE units through qualifying activities like training, higher-level certifications, or relevant work documented through CompTIA's system, or simply retake the current version of the exam before your three years run out. Letting the certification lapse means starting over rather than renewing, so most people either enroll in the CE program or calendar a reminder well before the expiration date.

How Network+ Compares to Its Closest Alternative

The natural comparison is Cisco's CCNA. Network+ is vendor neutral and tests concepts that transfer across any manufacturer's equipment, while CCNA is built entirely around Cisco's IOS and command-line environment. Network+ is generally considered the easier and less expensive entry point, and many people treat it as a stepping stone toward CCNA rather than a competing choice. If your target employer runs a Cisco shop, CCNA carries more direct weight in hiring conversations. If you want a credential that proves general networking competence without betting on one vendor's ecosystem, Network+ is the better fit, and it remains a common baseline requirement in government and defense-adjacent IT roles under the DoD 8140 framework.

Preparation Timeline

Most first-time candidates with some prior IT exposure report 8 to 12 weeks of consistent study, at somewhere between 5 and 10 hours a week, though this varies a lot based on whether you already have hands-on networking experience. Someone coming in cold, without any prior IP addressing or subnetting practice, should expect to lean toward the longer end of that range. The performance-based questions specifically reward lab time over reading time, so budgeting a portion of that study window for hands-on practice, whether through a home lab, a simulator, or CertMaster Perform, tends to matter more than an extra week of flashcards.
