As a network administrator, you will design a network that supports current needs and future needs. You will also ensure that it responds well to failures and limits the scope of those failures. Your goal will be to design a highly available, scalable network that is responsive to failures. This course identifies how to build a modular network and the benefits received from doing so. It introduces you to a hierarchical model built of layers that will provide many benefits. It also covers the benefits and drawbacks of virtualization.

Target Audience
This path is intended for anyone who is interested in developing the skills needed to successfully design networks that will support voice, video, and data communications.
