Book DescriptionLooking to pass the CompTIA Network+ N10-009 exam and advance your IT career? Employers seek certified professionals who can design, secure, and troubleshoot modern networks. Memorizing concepts won't cut it-you need a practical grasp of networking concepts, and this guide helps you build exactly that. Ian Neil, bestselling author of some of the most trusted CompTIA certification resources and a world-class CompTIA trainer, provides 100% coverage of all N10-009 exam objectives.
You'll start with the networking fundamentals, including the OSI model, topologies, ports, and protocols, then progress to configuring IPv4/IPv6 addressing, routing, switching, VLANs, and wireless networks. You'll master transmission media and transceivers and strengthen your security expertise with VPNs, IPSec, NAC, IDS/IPS, Zero Trust, and firewalls.
Beyond exam prep, this book explores cloud, virtualization, IoT, SDN, and SD-WAN, ensuring you're prepared for modern IT environments. It helps build your troubleshooting skills using tools such as SNMP, NetFlow, Wireshark, log analysis, and traceroute.
With practice questions across 25 chapters, 2 full-length online mock exams, 400 exam-style questions, and a 12% exam discount voucher, this guide equips you with the knowledge, experience, and confidence to earn your Network+ certification on the first try.What you will learn
Map OSI layers and TCP/IP protocols to real-world scenarios
Configure routers, switches, and firewalls using IPv4/IPv6 addressing
Apply cloud, virtualization, and SD-WAN concepts with VPC and Direct Connect
Recognize common ports and protocols such as DNS, DHCP, SNMP, and HTTPS
Implement wireless standards (802.11ax/6E), WPA3, and cellular IoT
Design resilient topologies like star, mesh, and spine-leaf architectures
Secure networks with VPNs, IPSec, NAC, and zero trust principles
Troubleshoot using SNMP, NetFlow, packet capture, and traceroute
Who this book is forThis book is for early-career IT professionals preparing for the CompTIA Network+ (N10-009) certification, including network administrators, help desk technicians, and junior systems engineers. Candidates are expected to have 9-12 months of hands-on networking experience and a solid understanding of basic IT concepts, though this guide could also be useful for students and career changers who want to build their foundational networking skills. It's also valuable for those pursuing further certifications like CompTIA Security+ or vendor-specific networking tracks.
