Study Notes

Foundational Network Concepts and Topologies

  • Star Topology: Most devices connect to a central hub.
    • Disadvantage: If that central hub fails, the whole network goes down (it's a single point of failure).
  • Hybrid Topologies: These combine different types of topologies to create more complex and flexible network structures.
  • Advanced Network Topologies: Spine-Leaf Topology
    • This is a modern data center design.
    • It consists of two layers:
      • Spine switches: These form the backbone, connecting all leaf switches.
      • Leaf switches: These connect to the end devices (like servers) and uplink to the spine switches.
