A good network design is crucial for network survival, with two network architectures highlighted in the video. Understanding the network design in your company, whether it's two-tier, three-tier, or another model, is crucial for optimizing network performance and scalability.
Insights
- Single points of failure in network setups pose significant risks, emphasizing the importance of implementing redundancy through a two-tier network architecture.
- The core switch in a three-tier network design model plays a critical role as the backbone of the network, boasting low latency and high reliability, essential for optimal network performance and scalability.

Recent questions
What is the importance of network design?
Network design is crucial for network survival, as it determines the structure and functionality of a network. A well-designed network ensures efficient communication, scalability, and reliability.
How can single points of failure be avoided in network setups?
Single points of failure can be avoided by implementing a two-tier network architecture, which includes access switches and a distribution switch. This design helps distribute the workload and prevents the entire network from failing if one component malfunctions.
What are the key functions of the distribution layer in network architecture?
The distribution layer, also known as the aggregation layer, handles tasks like route filtering, VLAN routing, and security policies. It acts as an intermediary between the access layer and the core layer, ensuring efficient data flow and network security.
Why is redundancy important in network design?
Redundancy in network design is crucial to eliminate single points of failure and ensure network reliability. By adding more devices like distribution layer switches and routers, redundancy helps maintain network uptime and performance.
What are the benefits of a three-tier network design model?
A three-tier network design model is beneficial for scenarios where multiple buildings need to be connected. It provides scalability, efficient data flow, and improved network performance by adding additional layers of switches to the architecture.
