Course Overview

Overview
CompTIA’s Network+ certification is a foundation-level certification designed for IT professionals with around one year of experience, whose job role is focused on network administration.

CompTIA Network+ validates the core skills necessary to establish, maintain, troubleshoot and secure networks in any environment, preparing you for a rewarding career in networking and cybersecurity.

CompTIA Network+ is the only certification on the market that covers the core skills necessary to support networks in any environment.

Network+ is Approved for DoD 8140.03. CompTIA Network+ shows what you can do, not just what you know for the work roles of Technical Support Specialist, Network Operations Specialist and Systems Administrator.

Objectives
During the CompTIA Network+ (Preparation for Exam N10-009) course, students will learn:
Networking Concepts: Explain basic networking concepts, including the OSI model, network appliances, applications, cloud concepts, connectivity options and more.
Network Security: Understand security concepts and network attacks to harden networks against threats.
Network Implementations: Understand routing technologies and important factors of physical installations; configure switching technologies and wireless devices.
Network Troubleshooting: Explain the troubleshooting methodology and address common issues related to networking, including cable, connectivity, and software problems.
Network Operations: Monitor and optimize networks to ensure business continuity.
Audience
Technical Support Specialist, Network Operations Specialist and Systems Administrator.

Prerequisites
Recommended experience: CompTIA A+ certification and a minimum of 9-12 months of hands-on experience working in a junior network administrator/network support technician job role.
