CompTIA Network+ Domain #2: Infrastructure

by Greg Belding on February 28, 2019

Introduction

The CompTIA Network+ exam is composed of five Domains of knowledge that you need to traverse to earn a passing score, and ultimately, the Network+ certification. This article will detail Domain #2, Infrastructure.

As you will see, it is one of the most physically-focused of all the Domains. If you are an information security or IT professional that lives for the physical end job, such as cable and networking device placement, this will be your favorite Domain.

Please note: This article should not serve as your sole means of preparing for the Network+ certification exam, but rather as a general review or an outline.

Infrastructure Outline

2.1 Deploying the appropriate cabling solution

2.2 Determining networking device placement and how to install/configure

2.3 Advanced networking device purposes and use cases

2.4 The purposes of network storage technologies and virtualization

2.5 Compare and contrast different WAN technologies

2.1 Deploying the Appropriate Cabling Solution
