QuestionQ44

Layer 3 Fabrics

You are designing an IP fabric for a large data center and are concerned about scalability as it grows.

Which two actions should you take to address these concerns?

Choose two
  • A Use EX4300 Series devices as the spine devices.
  • B Design a three-stage Clos IP fabric.
  • C USE QFX5700 Series devices as the super spines.
  • D Design a five-stage Clos IP fabric.
Explanation

A five-stage Clos architecture adds a super-spine aggregation layer that interconnects multiple pods, enabling the fabric to scale beyond a three-stage design. QFX5700 Series switches provide high-density interfaces for spine-and-leaf data-center deployments and can serve as scalable super-spine platforms. Juniper documents that five-stage Clos topologies support large-scale designs by interconnecting multiple pods through super-spine devices.
