The CompTIA Network+ certification helps IT students build real-world skills that align with the day-to-day responsibilities of entry-level professionals. To pass the exam, students must demonstrate technical knowledge and problem-solving capabilities. The exam breaks this into five core domains. Each one reflects practical scenarios you’ll likely face on the job, from basic configurations to system recovery.
1. Networking Concepts
This domain lays the groundwork for how digital communication flows across modern networks. You’ll dive into topics like IP addressing, ports, and key protocols such as TCP, UDP, and DNS. These theoretical terms correlate to how devices talk to each other inside business environments. Additionally, many roles that require Network+ certification, like IT Technician or Support Specialist, involve diagnosing connection failures or misconfigured services.
2. Infrastructure
This section covers the hardware and physical systems behind every functioning network. Expect to study switches, routers, fiber types, connectors, and power-related tools like PoE. You’ll also review wireless standards, cabling topologies, and setup guidelines for SOHO (small office/home office) networks. Technicians in early-stage roles often set up or troubleshoot these components. Dion Training reinforces this part of the certification through labs and real-world scenarios designed to mirror what students will encounter once they step into a role.
3. Network Operations
Here, the focus shifts to performance, monitoring, and documentation. You’ll review log files, learn to interpret SNMP traps, and work with diagramming strategies that help teams manage growing infrastructure. From there, the exam will ask about baseline metrics and change management processes that help prevent outages. Professionals in roles like Network Administrator rely on these systems to keep things running smoothly.
4. Network Security
This domain highlights tools and techniques that protect sensitive data and prevent attacks. Topics include firewalls, VPNs, authentication protocols (like RADIUS and TACACS+), and physical security controls. You’ll also study threat types like social engineering and DDoS attacks.
Entry-level tech roles increasingly require some familiarity with security fundamentals. Dion Training includes this section in its CompTIA certification prep using layered learning modules, starting with vocabulary and progressing into use cases tied to common workplace threats.
5. Network Troubleshooting and Tools
Most job interviews for IT support or network roles include questions about problem-solving. This domain prepares students to tackle slow connections, dropped signals, or IP conflicts using tools like tracert, ping, and ipconfig. Scenarios ask you to walk through an issue step-by-step and find a clear fix. Students using Dion Training’s CompTIA Network+ materials practice these exact skills through interactive examples and timed assessments. That way, they’re better prepared for the exam and on-the-job troubleshooting.
How Dion Training Supports CompTIA Network+ Students
Passing the CompTIA Network+ certification is a huge step for anyone looking to land a job in IT support, systems management, or network administration, but exam prep shouldn’t feel like you're figuring it out alone. Dion Training’s courses are built to make every topic easier to digest, every lab more useful, and every study session more productive.
What the Network+ Course Includes
Students in our CompTIA Network+ course gain access to over 30 hours of video training, broken down into short, digestible lessons. These segments cover essential areas like network implementation, troubleshooting methods, infrastructure components, and protocols.
Course materials also include the official CompTIA Network+ (N10-009) study guide, downloadable resources, and a full set of hands-on labs that replicate real-world networking environments. These scenarios give students practice with tasks they’ll face in jobs like IT Technician or Network Support Specialist.
Pricing, Access, and What You Get
Every Network+ certification bundle comes with 12 months of course access, giving you the freedom to study at your own pace—no deadlines, no pressure to cram. We also include our 60-day pass guarantee: finish the course and don’t pass on your first try? We’ll cover the cost of your retake.
If you’re planning or comparing certification options, you can check out our CompTIA costs blog for a full breakdown of what to expect. We also offer exam vouchers and Take2 retake vouchers that make it easier to register and retest, all in one place.
Why These Tools Set Students Up for Success
Course design focuses heavily on real-world relevance. The combination of visual instruction, scenario-based labs, and exam-style quizzes reinforces skills rather than just testing memory. Since we’re also a CompTIA Platinum Partner, students also benefit from insights that track closely with exam updates and evolving industry standards.
