What are the three layers of the switch hierarchical design model? (Choose three.)

Introduction

The Cisco Certified Network Associate (CCNA) 200-301 exam is a fundamental certification for networking professionals. One of the key topics covered in this exam is the switch hierarchical design model, which is crucial for designing scalable, efficient, and manageable networks.

In this article, we will explore the three layers of the switch hierarchical design model, their functions, and their importance in network architecture. Additionally, we will discuss how Study4Pass can help you prepare effectively for the CCNA 200-301 exam with high-quality exam dumps and study materials.

Understanding the Switch Hierarchical Design Model

The switch hierarchical design model is a framework used to design enterprise networks in a structured and modular way. This model ensures scalability, redundancy, and optimal performance by dividing the network into three distinct layers:

Core Layer
Distribution Layer
Access Layer

Each layer has specific roles and responsibilities, contributing to a well-organized and efficient network infrastructure.

Core Layer (The Backbone of the Network)

Function:

The Core Layer is the high-speed backbone of the network, responsible for fast and reliable data transport between different parts of the network. It connects multiple distribution layers and ensures seamless communication.

Key Characteristics:

High-speed switching (e.g., 10Gbps, 40Gbps, or 100Gbps links)
Minimal packet manipulation (no ACLs, filtering, or VLAN routing)
Redundancy and fault tolerance (using protocols like HSRP, VRRP)
Low latency and high availability

Devices Used:

High-performance switches (e.g., Cisco Catalyst 6500, Nexus 7000)

Importance:

Ensures fast data transfer between different network segments.
Provides scalability for large enterprise networks.
Enhances reliability with redundant paths.

Distribution Layer (The Mediator Between Core and Access Layers)

Function:

The Distribution Layer acts as an intermediary between the Core Layer and the Access Layer. It performs routing, filtering, and policy enforcement to manage traffic flow efficiently.

Key Characteristics:

Routing between VLANs (Inter-VLAN routing)
Traffic filtering and security policies (ACLs, QoS)
Aggregation of Access Layer switches
Redundancy and load balancing

Devices Used:

Multilayer switches (e.g., Cisco Catalyst 4500, 3650)

Importance:

Segments network traffic to reduce congestion.
Enforces security policies (firewalls, access control).
Improves network efficiency by aggregating multiple Access Layer switches.

Access Layer (The Entry Point for End Devices)

Function:

The Access Layer is where end devices (computers, IP phones, printers) connect to the network. It provides user access and basic network services.

Key Characteristics:

Port security (MAC address filtering)
VLAN assignment (separating traffic logically)
PoE (Power over Ethernet) for devices like IP phones and cameras
Basic traffic filtering

Devices Used:

Layer 2 switches (e.g., Cisco Catalyst 2960, 9200)

Importance:

Connects end-users to the network.
Enhances security with port-based controls.
Simplifies network management through VLAN segmentation.

Why is the Hierarchical Model Important?

Scalability – Allows networks to grow without redesigning the entire infrastructure.
Performance Optimization – Reduces bottlenecks by distributing functions across layers.
Easier Troubleshooting – Isolates issues to specific layers.
Enhanced Security – Implements policies at different levels.
Cost Efficiency – Uses appropriate devices for each layer, avoiding overspending.
