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 available after the course. The exam
consists of 40 questions and lasts 1.5 hours.

"Very useful for understanding networks and network design."
"Very good instructor, clear outlines and objectives and a lot of hands on."
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.
