Network communications and capture basics + DNS protocol decoding and troubleshooting

Next sessions : 20/03/2018 - 29/05/2018 - 25/09/2018

Overview

Many organizations use monitoring and troubleshooting tools but few of them are really able to take all benefits from these solutions.
The reason is quite simple: a tool that is able to automatically troubleshoot complex performance degradation problems does not exist. Nothing will ever replace the human expertise that is required to interpret the information provided by such monitoring platforms.
A detailed transactional analysis of performance degradation problems is only possible if there is an understanding of network protocols in place.
This training focuses on the basics of network communications and analyses the DNS protocol in details.

Objectives

This training aims to help participants acquire the necessary basic technical knowledge about network based communications and DNS protocol. It will enable them to get a good understanding of network communications principles as well as network traffic capture methods. It will also help them troubleshoot DNS related performance degradations.
