The three-layer hierarchical model describes what aspect of networks?

• A. Network security
• B. Data modeling
• C. Queue management
• D. Network topology

Answer: (D)

The three-layer hierarchical model is a foundational framework commonly used to understand and design network topologies. This model breaks down the network into three distinct layers: the Core, Distribution, and Access layers. Each layer serves specific functions and responsibilities, facilitating efficient data flow and management across the network. - The Core layer is responsible for the high-speed transport of data across different networks and connecting to multiple distribution layers. - The Distribution layer acts as an intermediary, handling routing, filtering, and WAN access, while also performing Quality of Service (QoS) management for the traffic passing through. - The Access layer connects end devices to the network and controls user access. This structured approach allows for scalability, easier management, and enhanced performance of a network, making it crucial for planning and operational efficiency. Understanding this model helps in designing robust networks that can support various services and applications effectively.

• The Core layer is responsible for the high-speed transport of data across different networks and connecting to multiple distribution layers.

• The Distribution layer acts as an intermediary, handling routing, filtering, and WAN access, while also performing Quality of Service (QoS) management for the traffic passing through.

• The Access layer connects end devices to the network and controls user access.
