CCNA Full Course in 2022 | CCNA 200-301 Full course in 2022 - Class 6

In this CCNA Full Course I have covered the exam title CCNA 200-301 Fundamental Concept I have created this CCNA 200-301 Full Course Series for Beginners.

Hierarchical network design model breaks the complex problem of network design into smaller and more manageable. Each layer or tier in the hierarchy is focused on specific set of roles. This helps the network designer and architect to optimize and select the right network hardware, software and features to perform specific roles for that network layer the two proven hierarchical design architectures for campus networks are the 1.Three-tier model 2.Two-tier model
Two-tier layer model This design model, is more suitable for small to medium-size campus networks Many small enterprise networks do not grow significantly larger over time as large organization grow. In such network the core and distribution functions can be combined into one layer, also known as collapsed core-distribution architecture. A “collapsed core” is when the distribution layer and core layer functions are implemented by a single device. The primary motivation for the collapsed core design is reducing network cost, while maintaining most of the benefits of the three-tier hierarchical model.
