QUESTION: 158

What is a function spine-and-leaf architecture?

Offers predictable latency of the traffic path between end devices.
Exclusively sends multicast traffic between servers that are directly connected to the spine.
Mitigates oversubscription by adding a layer of leaf switches.
Limits payload size of traffic within the leaf layer.

Answer(s): A

Explanation:

With a spine-and-leaf architecture, no matter which leaf switch to which a server is connected, its traffic always has to cross the same number of devices to get to another server (unless the other server is located on the same leaf). This approach keeps latency at a predictable level because a payload only has to hop to a spine switch and another leaf switch to reach its destination.
