Which network topology utilizes a two-layer hierarchical design where each access switch connects to every core switch, providing consistent latency and high-bandwidth connectivity between any two endpoints?
Star topology
Three-tier topology
Spine-leaf topology
Ring topology
The spine-leaf topology is a two-layer network design where every leaf (access) switch connects to every spine (core) switch. This architecture provides consistent latency and high-bandwidth connectivity between any two endpoints in the network, making it ideal for data centers with heavy east-west traffic. Unlike three-tier topologies, which add an aggregation layer and can introduce bottlenecks, the spine-leaf design ensures all devices are a predictable number of hops away. Star and ring topologies do not provide the same level of scalability and bandwidth for large networks.
