Overview

An intensive generic hands on IP foundation. The course focuses on all parts of IP networking: layer 2 on switches, layer 3 on routers and layer 4 on transport. Layers 5 to 7 are also covered.

Delegates will build and troubleshoot routed and switched networks, as well as VLANs and InterVLAN routing. Hands on sessions are used to reinforce the theory rather than teach any specific manufacturer’s equipment.

This course is also ideal for IT professionals from other backgrounds who are finding IP is more involved in their work.

This course also teaches how to subnet numbers in seconds

How do QA’s online courses work?

QA online courses, also commonly known as distance learning courses or elearning courses, take the form of interactive software designed for individual learning, but you will also have access to full support from our subject-matter experts for the duration of your course. When you book a QA online learning course you will receive immediate access to it through our e-learning platform and you can start to learn straight away, from any compatible device. Access to the online learning platform is valid for one year from the booking date.

All courses are built around case studies and presented in an engaging format, which includes storytelling elements, video, audio and humour. Every case study is supported by sample documents and a collection of Knowledge Nuggets that provide more in-depth detail on the wider processes.
