Overview

Network technicians and administrators are in high demand, and that demand is only growing. The CompTIA Network+ is widely recognized as the essential certification for all network technicians as well as a vendor-neutral stepping stone to vendor-specific network implementation credentials. It also confirms that holders have the foundational knowledge required for network security roles such as cybersecurity analyst, engineer, and pentester. That's a lot of words to say that every tech and aspiring network administrator should get CompTIA Network+ certified. And this book is all you need to prepare.

Scott Jernigan, a trainer with decades of experience preparing people for certification exams, covers Network+ exam objectives in depth but also includes practice tests, recommendations for industry tools, and a corresponding video course. You'll explore everything from foundational concepts to the nitty-gritty of securing, monitoring, and troubleshooting your networks.

The CompTIA Network+ starts IT careers—this guide will show you the way.

  • Explore network architecture and topologies
  • Set up network connectivity in a local office, to the internet, and to the cloud
  • Monitor network speed and load
  • Deliver a secure network and keep up with attacks and trends
