Question 940
A guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. Which first diagnostic check is most useful before changing the network?
Explanation
Correct Answer
This check collects evidence at the layer implicated by the symptom: the certificate identity check fails before users can safely trust the HTTPS portal. Examine the evidence before choosing the corrective change.
Incorrect Answers
This would be a reasonable check when a campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring, but is less direct for the issue at hand: the certificate identity check fails before users can safely trust the HTTPS portal.
This would be a reasonable check when a company wants enterprise WLAN admission but plans to deploy a shared WPA2 personal passphrase to every employee, but is less direct for the issue at hand: the certificate identity check fails before users can safely trust the HTTPS portal.
This would be a reasonable check when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions, but is less direct for the issue at hand: the certificate identity check fails before users can safely trust the HTTPS portal.
