Question

In what way does a spine-and-leaf architecture enable network scalability when additional access ports are needed?

A A spine switch and a leaf switch can be added with redundant connections between them.
B A spine switch can be added with at least 40 GB uplinks.
C A leaf switch can be added with connections to every spine switch.
D A leaf switch can be added with a single connection to a core spine switch.

Explanation

A spine-and-leaf design scales access by adding another leaf switch, since leaf switches are the layer that provides endpoint-facing access ports. In a proper spine-and-leaf fabric, each leaf connects to every spine switch so the new leaf gains full fabric connectivity, consistent pathing, and redundancy without changing the existing topology.
