JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2022) — Question 14

Your campus EX9200 core devices are highly oversubscribed on bandwidth ans reporting massive dropped packets. To immediately address the issue, you decide to implement shaping on all interfaces.
Which action will accomplish?

Answer options

• A. Apply the input-shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.
• B. Define a CoS input traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.
• C. Define a CoS output traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.
• D. Apply the shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.]

Correct answer: C

Explanation

The correct answer is C because shaping is applied to outgoing traffic to manage bandwidth effectively, which is crucial for reducing dropped packets during high traffic. Options A and B incorrectly focus on input traffic, which will not alleviate the oversubscription issue. Option D also incorrectly applies shaping at the input level rather than the output level, which is necessary for effective traffic management.
