JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 47

You have configured CoS on a Junos device. A packet is classified as best effort by a behavior aggregate (BA) classifier, and as expedited forwarding by a multifield (MF) classifier.
Which statement is true in this scenario?

Answer options

• A. The packet will be placed in a queue associated with the BA classifier.
• B. The packet will be placed into the queue which is least congested.
• C. The packet will be placed into the queue that has the most bandwidth assigned to it.
• D. The packet will be placed in a queue associated with the MF classifier.

Correct answer: A

Explanation

In this scenario, the correct answer is A because when there are conflicting classifications, the packet is prioritized based on the behavior aggregate classifier's designation. The other options are incorrect as they either introduce irrelevant criteria for queue placement or misrepresent the handling of the packet in terms of the classification hierarchy.
