JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2022) — Question 19

You recently deployed CoS-based forwarding in your network, which uses OSPF as its IGP. You notice that the forwarding of traffic has not changed and is not following the path indicated within your configuration.
In this scenario, which statement explains this behavior?

Answer options

• A. The defined policy references IP addresses as the next-hops instead of interface names.
• B. Load balancing has not been enabled under [edit forwarding-options].
• C. The defined policy references interface names as the next-hops instead of IP addresses.
• D. The defined policy has not been applied under [edit class-of-service forwarding-policy].

Correct answer: A

Explanation

The correct answer is A because if the policy is referencing IP addresses instead of interface names, it may not be directing traffic correctly as intended in the configuration. Option B is incorrect since load balancing does not directly impact the forwarding path defined by CoS. Options C and D are also incorrect as they do not accurately describe the issue affecting traffic forwarding in this scenario.
