Architect the solution

You are implementing a spine-and-leaf architecture using 18 CX 8360-48Y6C v2 leaf switches and two CX 8325-32C spine switches. The leaf switches support servers with 10- and 25-GbE ports. You currently plan to use two 100-Gbps uplinks per leaf switch.

The customer now requires at least a 50% increase in uplink bandwidth per leaf switch. What is a valid modification to the plan?

  • A Convert both uplinks on each leaf switch (and connected spine switches) to 200 GbE links
  • B Add a third CX 8325-32C switch and connect it to each leaf switch with a 100 GbE link
  • C Add another 100 GbE link to each leaf switch. One switch in each VSX pair connects to spine 1, and one switch connects to spine 2.
  • D Add another 100 GbE link between each leaf switch and both spine switches
Explanation

A third 100-GbE uplink raises each leaf switch’s uplink capacity from 200 GbE to 300 GbE, meeting the 50% increase. Distributing the additional links across the two members of each VSX leaf pair adds nine leaf-facing ports to each spine, for 27 ports per CX 8325-32C—within its 32 40/100-GbE QSFP+/QSFP28 ports.
