Question 830
During a planned campus-network change at an engineering school in Copenhagen, operators discover that an analyst uses unrelated packets from a management port to diagnose a wireless client authentication failure. The design must preserve lab networks and WLAN testing. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the Port mirroring, packet capture and evidence requirement at an engineering school in Copenhagen. The expected result is that a controlled test flow appears on the capture destination with accurate timestamping and without unexpected payload loss. The necessary correction is to mirror the correct source interface or VLAN to a capture destination and verify direction, rate and visibility before interpreting the PCAP; a saved configuration alone would not prove it is working. In this case, the observed fault is that an analyst uses unrelated packets from a management port to diagnose a wireless client authentication failure.
Incorrect Answers
At an engineering school in Copenhagen, the observation may be useful for a separate UXI, Central alerts and authenticated APIs test, but it does not establish that an analyst uses unrelated packets from a management port to diagnose a wireless client authentication failure has been resolved. The relevant check is the Port mirroring, packet capture and evidence outcome.
At an engineering school in Copenhagen, this measures a different network requirement, NAE analytics script and operational alerts. The case describes that an analyst uses unrelated packets from a management port to diagnose a wireless client authentication failure, so accepting this result would leave the primary fault without direct verification.
At an engineering school in Copenhagen, the observation may be useful for a separate Queue scheduling and congested egress test, but it does not establish that an analyst uses unrelated packets from a management port to diagnose a wireless client authentication failure has been resolved. The relevant check is the Port mirroring, packet capture and evidence outcome.
