Dive into the foundational architecture of modern enterprise networks. This module explores the classic Three-Tier hierarchical model (Core, Distribution, and Access layers) and the Collapsed Core alternative. You will learn the specific roles, design requirements, and best practices for each layer, how to identify and eliminate Single Points of Failure (SPOFs), and how to translate business requirements like scalability and uptime into robust physical and logical topologies. Perfect for network engineers preparing for CCNP Enterprise or transitioning into architecture roles.
