JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 9

A BA classifier, input policer, and a multifield classifier are applied to an interface.
In which order are these features processed?

Answer options

• A. policer ""> BA classifier ""> multifield classifier
• B. policer ""> multifield classifier ""> BA classifier
• C. multifield classifier ""> BA classifier ""> policer
• D. BA classifier ""> multifield classifier ""> policer

Correct answer: A

Explanation

The correct order is policer > BA classifier > multifield classifier, as the input policer first checks the traffic for compliance before it goes to the BA classifier for classification and then to the multifield classifier for further processing. The other options misplace the order, which would not reflect the correct processing sequence in traffic management.
