Question 230
At the Northport multisite corporate network, a team enables QoS but cannot explain why a critical application's packets still enter best-effort queues. What risk should the team identify as the primary issue?
Explanation
Correct Answer
This identifies the root issue: a configured policy may not match traffic or may be rewritten further along the path. At the Northport multisite corporate network, the team should therefore inspect the classification rules DSCP mappings and per-queue counters at each relevant hop.
Incorrect Answers
The option states: A single congested best-effort queue does not protect latency-sensitive voice packets. By contrast, the current situation is governed by: a configured policy may not match traffic or may be rewritten further along the path. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.
The offered alternative states: Open access ports cannot distinguish authorized identities before granting network privileges. The reported facts point to a different controlling condition: a configured policy may not match traffic or may be rewritten further along the path. The alternative does not directly settle the required root-cause explanation.
A device without an EAP supplicant cannot complete the chosen port identity protocol. In this question, the decisive issue is: a configured policy may not match traffic or may be rewritten further along the path. That is why the offered option is not the most direct root-cause explanation.
