Network design  |    A 5 day   hands on   training course

Network design training course description

This course provides you with the knowledge needed to perform the design of a network infrastructure that supports desired network solutions to achieve effective performance, scalability, and availability. We recognise that the role of design does not normally require hands on skills but hands on sessions are used to reinforce the theory not to teach configuration or troubleshooting.

What will you learn
  • Create HA enterprise network designs.
  • Develop optimum Layer 3 designs.
  • Design effective modern WAN and data center networks.
  • Develop effective migration approaches to IPv6.
  • Create effective network security designs.

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.
