JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2023) — Question 71

You must alter class-of-service values in packets on the outbound interface of an edge router.

In this scenario, which CoS component allows you to accomplish this task?

Answer options

• A. output policer
• B. scheduler
• C. rewrite rules
• D. forwarding classes

Correct answer: C

Explanation

The correct answer is C, as rewrite rules are specifically designed to change the class-of-service values before packets leave the router. The other options, such as output policer and scheduler, manage traffic flow and scheduling but do not directly alter CoS values.
