QuestionQ20

Architect the solution

Several years ago, you delivered an L3 spine-and-leaf topology to a customer. The solution used two CX 8325-32C switches as spines and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs.

The customer now wants to double the topology’s forwarding capacity. What should you recommend?

  • A Add two more 100GbE links between each leaf switch and spine switch
  • B Upgrading the existing links to 200 GbE
  • C Adding one more spine switch that connects to each leaf switch with two 100 GbE links
  • D Adding two more spine switches that connect to each leaf switches with 100 GbE links
Explanation

Two additional CX 8325-32C spine switches, each connected to every physical leaf by one 100GbE link, expand the fabric from two to four spines and double its aggregate forwarding capacity. Each added spine needs 20 ports, which fits within its 32 high-speed ports. A single added spine using two links per 20 leaves would require 40 ports and exceeds that spine’s port capacity.
