A regional municipal data center plans to grow from dozens of leaves to hundreds while keeping non-blocking east-west capacity. How should the architects scale the Clos fabric?
Select an answer to reveal the explanation.
Short Explanation
Think of a Clos like a highway system: when traffic grows, you add lanes and on-ramps—more spines and leaves—not one giant overpass. Horizontal scale-out is how a regional DC keeps bandwidth and ports climbing together.
Full Explanation
Leaf-spine Clos fabrics scale primarily by adding spines for uplink bandwidth and leaves for server attachment ports. That horizontal growth preserves multipath capacity. Collapsing to few chassis, converting the underlay to L2 trunks, or pinning traffic to one spine removes the scale and resiliency benefits of the IP fabric model.
