LINX 1

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