Question 650
At a utility control office in Raleigh, engineers report that a Wi-Fi user presents an expired client certificate and the SSID must not grant employee access. The work affects monitoring dashboards and service desk access. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the WPA3 Enterprise and EAP-TLS certificate authentication requirement at a utility control office in Raleigh. The expected result is that a valid managed certificate authenticates to the required role while expired or untrusted client identities are rejected. The necessary correction is to configure the appropriate enterprise SSID, trusted RADIUS service and mutual certificate validation for EAP-TLS; a saved configuration alone would not prove it is working. In this case, the observed fault is that a Wi-Fi user presents an expired client certificate and the SSID must not grant employee access.
Incorrect Answers
At a utility control office in Raleigh, this would verify WPA3 Personal, PMF and secure client compatibility, not the failure reported in this scenario. The requested closure criterion instead concerns WPA3 Enterprise and EAP-TLS certificate authentication: a valid managed certificate authenticates to the required role while expired or untrusted client identities are rejected.
At a utility control office in Raleigh, the observation may be useful for a separate Role-based wireless segmentation and policy test, but it does not establish that a Wi-Fi user presents an expired client certificate and the SSID must not grant employee access has been resolved. The relevant check is the WPA3 Enterprise and EAP-TLS certificate authentication outcome.
At a utility control office in Raleigh, this measures a different network requirement, Campus policy boundary and management hardening. The case describes that a Wi-Fi user presents an expired client certificate and the SSID must not grant employee access, so accepting this result would leave the primary fault without direct verification.
