An intensive hands on IP foundation. 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.
An optional 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.

"Very informative. Most informative and enjoyable course I have been on. Excellent!"The course provides an exceptional insight on the vast areas of data communications and networking."
"Very well thought out and structured course. Would recommend 100%. Lots of equipment, good quality. Gave insights in things you wouldn’t normally think about." "The course is highly educative. The course have meet more than my expectation, its so good. It’s wonderful, I'm OK with everything I saw."
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.
