TCP/IP foundation for engineers

A 5 day
HANDS ON
training course

TCP/IP training course description

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.

Key outcomes from this course

By the end of the course delegates will be able to:
  • 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 Whireshark.
  • Troubleshoot TCP/IP.

TCP/IP training course details

Who will benefit:
Technical staff working with networks.
Prerequisites:
None.
Duration:
5 days

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.

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
