A network engineer is tasked with designing a scalable and hierarchical network for a large organization with multiple departments and high traffic demands. Which network topology architecture best meets these requirements by introducing an intermediary layer to handle interdepartmental traffic and policy enforcement?
The three-tier architecture is ideal for large enterprise networks needing scalability and hierarchical design. It introduces a distribution layer between the core and access layers, which manages interdepartmental traffic, implements policies, and enhances performance. The two-tier architecture lacks this intermediary layer, making it less effective for large networks. Spine-leaf architecture is primarily used in data centers for east-west traffic patterns, not for hierarchical enterprise networks. Small office/home office (SOHO) architecture is designed for minimal network needs and doesn't support large-scale enterprise requirements.
