Network+ Certification (N+)

Scheduled Dates Locations filtered. Show all UK course locations.

Course Overview

The CompTIA Network+ certification has become an international standard for network engineering. This course allows network support engineers to develop their skills and prepare for the Network+ examination.

This course covers the knowledge and skills necessary to configure and install the TCP/IP client as well as a wide range of vendor and product neutral networking technologies. The aim of the certification is to allow computer network technicians to show they have the knowledge and skills required to perform a wide range of IT related tasks in the area of network support.

Audience

LAN support or administration personnel wishing to implement and manage their network more effectively.

Skills Gained

Delegates will learn how to:

• identify the functions of the OSI 7-Layer Model, associating networking functions and protocols within these layers
• describe the components of a network, identifying strengths and weaknesses of network types and configure network protocols
• outline the addressing and internetworking of the TCP/IP protocol suite, describe and configure basic IP functions and services
• troubleshoot IP, using in-built utilities
• describe the functions of Remote Access and configure dial-up connectivity, list and implement the main security features that will be required in a business network
• install a local area network, using TCP/IP, servers and clients
• formulate and test a troubleshooting methodology for a local area network, for both hardware, software and user faults

Examinations

This course also prepares delegates for the CompTIA Network+ examination.

Prerequisites

Delegates must have a working knowledge of PCs and network clients, e. g. Windows 9x or NT Workstation. It is also required that all delegates have an appreciation of PC hardware configuration, including IRQs, etc., and a fundamental understanding of the function of a LAN. These requirements may be satisfied by attending an A+/PC Support or Networking with TCP/IP course.
