LINX Accredited Internet Technician 1  |    A 5 day   hands on   training course

LINX 1 training course description

An intensive hands on IP foundation leading to LINX Accredited Internet Technician stage 1. The course focuses on all parts of TCP/IP including layers 4 to 7 on end stations as well as layer 3 on routers. The TCP/IP protocols are also studied to enable delegates to be able to troubleshoot TCP/IP using Wireshark. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.
A multiple choice exam, leading to the LAIT I certification, is included at the end of the course. The exam consists of 40 questions and lasts 1.5 hours.

What will you learn
  • Use ping, traceroute and other tools to diagnose faults on a network.
  • Configure IP on PCs and routers.
  • Plan IP addresses and subnets.
  • Analyse IP and TCP packets using an analyser.
  • Troubleshoot TCP/IP.

Training approach

This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning. Hands on sessions are used throughout to allow delegates to consolidate their new skills.
