Book Description

Looking 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.
