Passing CompTIA Network+
Passing CompTIA Network+
I recently passed the CompTIA Network+ certification exam, which was an important milestone in strengthening my networking and cybersecurity foundation. Network+ stood out to me because it covered many of the concepts that show up constantly in cybersecurity, including routing, switching, subnetting, wireless networking, ports, protocols, troubleshooting, and network security.
This certification helped connect a lot of material I had already seen through coursework, competitions, labs, and hands-on practice. It also reminded me that strong cybersecurity skills depend heavily on understanding how networks actually communicate.
Why I Took Network+
I wanted to take Network+ because networking is one of the core foundations of cybersecurity. Whether someone is working in defensive security, offensive security, cloud, incident response, or system administration, they need to understand how traffic moves and how systems communicate.
Some of the main topics I focused on included:
- TCP/IP (Transmission Control Protocol/Internet Protocol)
- OSI (Open Systems Interconnection) model
- Subnetting and CIDR (Classless Inter-Domain Routing)
- VLANs (Virtual Local Area Networks)
- DNS (Domain Name System)
- DHCP (Dynamic Host Configuration Protocol)
- Routing and switching concepts
- Wireless standards and security
- VPN (Virtual Private Network) concepts
- Network troubleshooting methodology
- Common ports and protocols
Rather than treating these as isolated topics, I tried to understand how they connected together in real network environments.
How I Prepared
My preparation process was based on consistent practice, review, and writing down mistakes. Whenever I missed a practice question, I wrote a short explanation of why the correct answer was right and why my answer was wrong. This helped turn each mistake into something I could actually learn from.
I spent extra time reviewing areas that were easy to confuse, such as ARP (Address Resolution Protocol) versus MAC (Media Access Control) address tables, VLANs versus subnetting, STP (Spanning Tree Protocol) versus RSTP (Rapid Spanning Tree Protocol), and TCP (Transmission Control Protocol) versus UDP (User Datagram Protocol).
Near the end of my preparation, I focused less on learning new material and more on reinforcing high-yield concepts like subnetting, common port numbers, troubleshooting steps, Cisco-style commands, and wireless security.
Exam Experience
The multiple-choice questions felt manageable because they matched the areas I had reviewed. The PBQs (Performance-Based Questions) were the most challenging part because they required applying concepts through diagrams, configuration choices, and troubleshooting scenarios.
That was one of my biggest takeaways: Network+ is not only about memorizing definitions. It also tests whether you can apply networking logic under pressure.

People and Resources That Helped
I want to thank the SWIFT club, Dr. West, and Professor Barrios from Coastline College for helping build my foundation and keeping me motivated throughout my cybersecurity journey.
I also want to thank Andrew Ramdayal on YouTube for creating Network+ preparation content that helped reinforce important concepts before the exam.
Final Thoughts
Passing Network+ gave me more confidence in my networking foundation and showed me how important fundamentals are in cybersecurity. Concepts like subnetting, routing, DNS, DHCP, VLANs, wireless security, and troubleshooting show up everywhere.
For anyone preparing for Network+, my biggest advice is to focus on understanding instead of only memorizing. Memorizing ports and acronyms helps, but being able to reason through scenarios is what matters most.
Overall, Network+ was a challenging but rewarding certification, and I am glad I took the time to build this foundation.
