Question 970
During a planned campus-network change at an engineering school in Copenhagen, operators discover that a QoS template uses the wrong output queue mapping on the target switch model. The design must preserve lab networks and WLAN testing. Which test result most directly confirms the required behavior?
Explanation
Correct Answer
This observation tests the Queue scheduling and congested egress requirement at an engineering school in Copenhagen. The expected result is that under representative congestion, loss and latency for the priority application meet policy and nonpriority classes continue to forward. The necessary correction is to apply the appropriate QoS scheduling/queuing policy for real-time traffic while preserving bandwidth for other classes; a saved configuration alone would not prove it is working. In this case, the observed fault is that a QoS template uses the wrong output queue mapping on the target switch model.
Incorrect Answers
At an engineering school in Copenhagen, this would verify Wireless coverage versus capacity and roaming tuning, not the failure reported in this scenario. The requested closure criterion instead concerns Queue scheduling and congested egress: under representative congestion, loss and latency for the priority application meet policy and nonpriority classes continue to forward.
At an engineering school in Copenhagen, the observation may be useful for a separate QoS classification and DSCP trust boundaries test, but it does not establish that a QoS template uses the wrong output queue mapping on the target switch model has been resolved. The relevant check is the Queue scheduling and congested egress outcome.
At an engineering school in Copenhagen, this would verify Wi-Fi airtime efficiency and data rates, not the failure reported in this scenario. The requested closure criterion instead concerns Queue scheduling and congested egress: under representative congestion, loss and latency for the priority application meet policy and nonpriority classes continue to forward.
