A city replaces STP access pods with a leaf-spine Clos for the new civic cloud. Which trait best describes that IP fabric architecture?
Select an answer to reveal the explanation.
Short Explanation
Think of the old STP pods as one-lane bridges with gates half-shut. The civic Clos opens every leaf-to-spine lane and lets Layer 3 ECMP share the load. Spines and leaves talk IP—no blocked fabric links as the architecture story.
Full Explanation
A Clos IP fabric uses a Layer 3 underlay between leaves and spines with equal-cost multipath for scale-out bandwidth. Spanning Tree is not the loop-prevention model for fabric links; routing provides loop-free multipath. Classic L2-mesh-plus-STP designs are what the city is leaving behind. Overlay services may still provide L2 adjacency, but the fabric underlay itself is routed.
