Network +  |    A 5 day   hands on   training course

Network+ training course description

This Network+ course covers the TCP/IP side of the exam. For delegates to pass the exam it is important that they meet the prerequisites, self study is also required. 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.

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.

"Very well executed training course, not as intense as expected, which created a very easy learning environment.”, “Thanks to all staff and trainers involved. Very friendly and easy going atmosphere."


E. B. – Thales:

"Excellent course. Learnt a lot. Enhanced what information I have picked up recently. Excellent knowledge base: instructor was very helpful and answered all questions with quality / concise answers to help."

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.
