CompTIA Network+ Certification Support Skills

5 Days

Introduction

CompTIA Network+ is the first certification IT professionals specialising in network administration and support should earn. Taking this course and using the study guide will help participants prepare for the certification.

Target Audience:

Network+ is aimed at IT professionals with job roles such as network administrator, network technician, network installer, help desk technician and IT cable installer.

Prerequisites

To ensure success, participants should meet the following criteria prior to taking the course:

Taken and passed both CompTIA A+ Certification exams or have 9-12 months knowledge and experience of IT administration.

  • Be able to configure and support PC, laptop, mobile (smartphone / tablet), and print devices.
  • Know basic network terminology and functions (such as Ethernet, TCP/IP, switches, routers).
  • Configure and manage users, groups, and shared resources in a simple SOHO network.
  • Understand the use of basic access control measures, such as authentication, security policy, encryption, and firewalls.

Programme Objectives

Participants will describe the major networking technologies, systems, skills, and tools in use in modern networks.

Upon successful completion of this course, participants will be able to:

  • Identify the basic network theory concepts.
  • Identify the major network communications methods.
  • Describe network media and hardware components.
  • Identify the major types of network implementations.
  • Identify the components of a TCP/IP network implementation.
