The first point of network contact for resources and end stations is the access layer. Will it be a Layer 2 or Layer 3 access layer? Do you need VLANs and Trunks? Will you have redundancy, and if so, is it causing loops that must be resolved? These questions will be answered in this course. This course analyzes the benefits and drawbacks of routed vs. switched access layers and the differences between End-to-End and Local VLAN deployments. It also considers the options you have when deploying Trunks and if VTP is needed or not. Lastly, it reviews the need for STP and the importance of proper STP design.

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.
