Question 210
At West Auditorium, a barcode scanner reauthenticates fully after every BSSID change because fast transition is disabled. Which postchange observation is the strongest evidence of correct operation?
Explanation
Correct Answer
For West Auditorium, the decisive mechanism is Roaming authentication stalls. Roaming interruptions can arise from authentication delay rather than RF coverage alone. Walk test the client and measure acceptable roam delay and loss supplies measurable, case-relevant evidence that the intended behavior actually occurs.
Incorrect Answers
This is relevant to RADIUS Access-Reject root cause, where an explicit RADIUS reject can come from credential validation or authorization policy In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone
This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone
This is relevant to DHCP address-acquisition failure, where network authorization and DHCP allocation are separate stages requiring their own diagnostics In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone
