What is a function of spine-and-leaf architecture?

Answer options

• A. offers predictable latency of the traffic path between end devices
• B. mitigates oversubscription by adding a layer of leaf switches
• C. exclusively sends multicast traffic between servers that are directly connected to the spine D.limits payload size of traffic within the leaf layer

Correct answer: A

Explanation

The correct answer, A, highlights that spine-and-leaf architecture is designed to ensure predictable latency for traffic paths, which is crucial for performance. Option B, while addressing oversubscription, does not directly relate to latency predictability. Option C inaccurately limits the function of the architecture to multicast traffic, and D incorrectly suggests a limitation on payload size, which is not a primary function of this architecture.
