QuestionQ17

Layer 3 Fabrics

You are deploying an IP fabric with a 3:1 oversubscription ratio.

In this scenario, which two statements are correct?

Choose two
  • A The oversubscription ratio remains the same when you remove leaf devices.
  • B The oversubscription ratio increases when you remove leaf devices.
  • C The oversubscription ratio decreases when you add leaf devices.
  • D The oversubscription ratio remains the same when you add leaf devices.
Explanation

An IP fabric’s oversubscription ratio is the ratio of workload-facing bandwidth to fabric-facing bandwidth at a leaf. Adding or removing leaf devices without changing their port allocations or uplink capacity does not change that per-leaf ratio, so a 3:1 oversubscription ratio is retained.
