Which two options are advantages of a spine and leaf architecture? (Choose two )

Spine-leaf architectures provide robust multipathing because every leaf switch connects to every spine switch, allowing traffic to use any available path between leaf switches without blocking, often leveraging ECMP.

This architecture is specifically designed to optimize east-west traffic (server-to-server communication within the data center) by ensuring that any two leaf switches are only one hop away from each other via a spine, minimizing latency and maximizing throughput.

A spine-leaf architecture is a specific form of a Clos network topology, not a simple star topology; it uses interconnected spine and leaf layers, which is more complex and offers different advantages than a simple star.

While north-south traffic (traffic entering/exiting the data center) can flow efficiently, the spine-leaf architecture's primary optimization and advantage are for east-west traffic, which typically dominates modern data center workloads.

While highly scalable, the scalability of a spine-leaf architecture is generally linear or additive by adding more spines and leaves, not typically "exponential" which implies a growth rate that is usually unachievable or refers to something that grows very quickly rather than in a predictable, modular fashion.
