JNCIP-DC: Juniper Networks Certified Professional – Data Center (2024) — Question 3

You are deploying a Clos IP fabric with an oversubscription ratio of 3:1.
In this scenario, which two statements are correct? (Choose two.)

Answer options

• A. The oversubscription ratio decreases when you add spine devices.
• B. The oversubscription ratio increases when you remove spine devices.
• C. The oversubscription ratio remains the same when you add spine devices.
• D. The oversubscription ratio remains the same when you remove spine devices.

Correct answer: A, B

Explanation

Adding spine devices increases the total capacity of the fabric, thus reducing the oversubscription ratio. Conversely, removing spine devices decreases capacity, leading to a higher oversubscription ratio. Therefore, options A and B are correct, while options C and D are incorrect.
