JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 34

You are designing an IP fabric underlay network in your data center. You must ensure that your traffic can be forwarded at line rate.
In this scenario, which oversubscription model should be used?

Answer options

• A. 2:1 oversubscription
• B. 1:2 oversubscription
• C. 3:1 oversubscription
• D. 1:1 oversubscription

Correct answer: D

Explanation

The correct answer is D, 1:1 oversubscription, as it allows for traffic to be forwarded at line rate without any congestion. The other options, such as 2:1, 3:1, and 1:2 oversubscription, would result in potential bottlenecks, meaning they cannot guarantee line rate forwarding under heavy loads.
