CompTIA Network+ Certification Guide 2026: N10-009 Exam, Cost and Training

The CompTIA Network+ certification validates practical networking skills across network concepts, implementation, operations, security, and troubleshooting. The current exam is CompTIA Network+ N10-009, with a maximum of 90 multiple-choice and performance-based questions completed in 90 minutes. CompTIA recommends roughly 9–12 months of networking experience. Effective preparation combines the official exam objectives, hands-on labs, a reliable CompTIA Network+ practice test, targeted study material, and timed practice exams rather than memorizing isolated facts.

What Is CompTIA Network+ Certification?

The CompTIA Network+ certification is a vendor-neutral networking credential designed to validate the skills needed to establish, manage, secure, monitor, and troubleshoot modern network environments.

Unlike certifications centered on one networking vendor, Network+ covers technologies and concepts that apply across different platforms. Candidates study wired and wireless connectivity, IP addressing, routing, switching, network services, cloud networking, security controls, monitoring, documentation, and troubleshooting.

The current network plus certification exam is N10-009. CompTIA's official objectives state that successful candidates should be able to establish network connectivity, configure common network services, explain cloud and virtual networking concepts, monitor network activity, apply network-security hardening, and troubleshoot network infrastructure.

For beginners, this makes Network+ a practical bridge between general IT support knowledge and more specialized networking, cybersecurity, cloud, and infrastructure roles.

The maximum-question count, time limit, formats, and recommended experience are confirmed in the official CompTIA exam objectives. The widely published passing score for N10-009 is 720 on CompTIA's scaled 100–900 scoring system.

A 720 score should not be interpreted as simply needing 72% of questions correct. CompTIA uses scaled scoring, so candidates should aim for broad mastery rather than trying to calculate exactly how many questions they can miss.

CompTIA Network+ Exam Objectives and Domain Weighting

The CompTIA Network+ exam objectives are divided into five domains. These percentages should directly influence your study plan.

Domain

Weight

Networking Concepts

23%

Network Implementation

20%

Network Operations

19%

Network Security

14%

Network Troubleshooting

24%

These are the official N10-009 domain weights.

Networking Concepts – 23%

Networking Concepts provides the technical foundation for the rest of the exam.

Candidates should understand the OSI model, IPv4 and IPv6, ports and protocols, network devices, cloud concepts, network architectures, addressing, routing fundamentals, and modern concepts such as software-defined networking.

This is where memorization can help with certain facts, such as common protocol functions, but understanding relationships is more important.

For example, memorizing that DNS resolves names is easy. A stronger candidate also understands how DNS failures affect application connectivity and how to distinguish a DNS problem from a routing or IP configuration problem.

Network Implementation – 20%

Network Implementation covers how networks are actually deployed.

Topics include switching, routing, wireless technologies, cabling, physical infrastructure, network appliances, and related configuration concepts.

A strong CompTIA Network+ course should not teach this section entirely through slides. Learners should practice building VLANs, examining routing tables, configuring wireless parameters, reading network diagrams, and troubleshooting incorrect configurations.

Network Operations – 19%

Network Operations focuses on keeping networks available and manageable after deployment.

Candidates should understand documentation, monitoring, configuration management, disaster recovery, high availability, environmental considerations, and operational procedures.

This domain matters because real networking work is not only about installing devices. Network professionals must also document environments, monitor performance, identify changes, and maintain service availability.

Network Security – 14%

Network Security tests the ability to recognize threats and apply appropriate security controls.

Candidates should understand authentication, authorization, secure protocols, network segmentation, hardening, physical security, common attacks, and security architecture concepts.

For someone planning to move toward cybersecurity, this portion of the network+ course provides an important foundation before studying deeper security credentials.

Network Troubleshooting – 24%

At 24%, Network Troubleshooting is the largest N10-009 domain.

This is also where candidates often discover whether they truly understand networking.

You may know what DHCP, DNS, VLANs, routing, and Ethernet do individually, but troubleshooting requires connecting those concepts.

If a workstation can communicate locally but cannot reach the internet, for example, you must determine whether the problem involves addressing, the default gateway, routing, DNS, firewall rules, or another dependency.

This is why a good CompTIA Network+ practice exam should contain troubleshooting scenarios rather than only definition-based questions.

How to Use a CompTIA Network+ Practice Test Effectively

A CompTIA Network+ practice test should measure readiness, not provide answers to memorize.

The best approach is to use practice tests in stages.

1. Begin with domain-specific questions while learning each section.

2. Record every incorrect answer and identify the objective behind it.

3. Revisit the concept using your CompTIA Network+ study guide or lab environment.

4. Repeat targeted network plus practice questions until you can explain the reasoning.

5. Move into a full Network+ practice exam under a 90-minute time limit.

Your review process matters more than the raw number of questions completed.

If you answer a question correctly because you guessed, treat it as a weak topic. Likewise, if you repeatedly miss questions involving subnetting, wireless channels, routing, or network services, return to those topics before taking another full test.

A legitimate CompTIA Network practice test should contain original or authorized practice material. CompTIA's own objectives explicitly warn against unauthorized third-party “brain dumps,” so candidates should use practice resources designed for learning rather than confidential live questions.

Performance-Based Questions Need Hands-On Preparation

One of the biggest mistakes candidates make is studying only traditional multiple-choice questions.

The real Network+ exam can include performance-based questions, commonly called PBQs. These may require you to interpret network information, troubleshoot a scenario, work with configurations, or apply concepts practically.

That means your CompTIA Network+ certification training should include labs.

Useful practice includes examining IP configurations, using command-line networking tools, understanding switch and router behavior, identifying cable and interface problems, working through DHCP and DNS issues, and reading network diagrams.

A candidate who can explain a VLAN but has never worked through a VLAN troubleshooting scenario may struggle more than expected.

Choosing CompTIA Network+ Study Material

Good CompTIA Network+ study material should map directly to the N10-009 objectives.

Before using a book, course, question bank, or video series, confirm that it specifically references N10-009 rather than the retired N10-008 exam.

A useful CompTIA Network study guide should provide concept explanations, practical examples, diagrams, command examples, troubleshooting scenarios, review questions, and coverage of all five exam domains.

Your resources should complement one another.

A textbook is useful for detail. Videos can clarify difficult concepts visually. Labs turn theory into skills. CompTIA Network+ practice questions test understanding. A timed exam tests whether you can apply that understanding quickly.

No single resource has to perform every job.

CompTIA Network+ Training: Online or Instructor-Led?

Both formats can work.

CompTIA Network+ training delivered online is useful for professionals who need flexible schedules and want to repeat difficult topics. Recorded demonstrations can also be helpful for subnetting, routing, wireless networking, and command-line tools.

Instructor-led CompTIA Network+ certification training may be more suitable for candidates who want a structured schedule, real-time explanations, lab guidance, and direct support when they get stuck.

Whichever format you choose, look for training aligned with CompTIA Network+ N10-009, practical labs, current exam objectives, scenario-based questions, and full-length mock exams.

A course that only explains terminology without troubleshooting practice is incomplete preparation.

CompTIA Network+ Certification Cost and Exam Voucher

The Network+ certification cost is primarily determined by the exam voucher, but the complete budget can include more than the test itself.

The CompTIA Network+ voucher is the authorization used to schedule the exam. Voucher pricing can vary by country, purchasing channel, eligibility program, taxes, institutional agreements, and available bundles.

That is why candidates searching for the CompTIA Network+ test cost or cost of Network+ certification should verify the current price through CompTIA or an authorized testing or voucher channel before purchasing.

Your total preparation cost may include the CompTIA Network+ exam voucher, study guide, online course, instructor-led training, labs, practice tests, and potentially another voucher if a retake is required.

Avoid choosing a preparation provider solely because it offers the cheapest voucher. Verify validity, region restrictions, expiration terms, and whether the seller is authorized.

A Practical Network+ Study Plan

A structured preparation sequence works better than randomly jumping between videos and network plus exam questions.

Start by downloading the current CompTIA Network+ exam objectives and use them as your master checklist.

Next, study Networking Concepts before progressing into implementation and operations. Build hands-on experience while learning rather than waiting until the final week.

When you reach troubleshooting, combine everything. Practice identifying whether a problem exists at the physical, addressing, routing, service, security, or application level.

Then begin mixed CompTIA Network+ practice exam sessions.

During the final stage, complete full timed practice tests and analyze every wrong answer. If a domain remains consistently weak, return to the objectives instead of simply taking another test.

Who Should Consider Network+?

Network plus is especially relevant for people pursuing roles such as IT support technician, network support specialist, junior network administrator, systems support professional, infrastructure technician, or cybersecurity professional who needs stronger networking fundamentals.

It can also be valuable before moving into more specialized networking or security certification paths.

The key benefit is breadth.

You learn enough about switching, routing, wireless networking, addressing, cloud infrastructure, network security, monitoring, operations, and troubleshooting to understand how modern networks work as an integrated system.

Your Next Step for the CompTIA Network+ Certification

Start your CompTIA Network+ certification preparation with the official N10-009 objectives rather than a random collection of exam questions. Give extra attention to Network Troubleshooting, which carries the highest domain weight at 24%, while maintaining balanced preparation across all five areas.

Use a current CompTIA Network+ study guide, practical labs, a structured CompTIA Network+ course, and realistic practice questions. Save full-length network plus practice exams for the stage when you have already covered the objectives and want to test pacing and decision-making.

The strongest indicator of readiness is not whether you recognize an answer from a question bank. It is whether you can look at an unfamiliar network problem, identify what is happening, choose the right diagnostic path, and explain why your solution makes technical sense.
