LINX 1 training course 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. 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. LINX 1 training course details Who will benefit: Network engineers. Prerequisites: None.
