JN0-683 · Question #37
You are deploying a Clos IP fabric with an oversubscription ratio of 3:1. In this scenario, which two statements are correct? (Choose two.)
The correct answer is B. The oversubscription ratio decreases when you add spine devices. C. The oversubscription ratio increases when you remove spine devices. The oversubscription ratio is the ratio of edge (leaf) bandwidth to core (spine) bandwidth. When you add spine devices, the total available core bandwidth increases, which reduces (decreases) the oversubscription ratio. When you remove spine devices, the total core bandwidth…

Explanation
The oversubscription ratio is the ratio of edge (leaf) bandwidth to core (spine) bandwidth. When you add spine devices, the total available core bandwidth increases, which reduces (decreases) the oversubscription ratio. When you remove spine devices, the total core bandwidth decreases while edge bandwidth remains the same, causing the oversubscription ratio to increase.
