Question 460
At West Auditorium, a backup RADIUS server is configured but never used when the first server is unreachable. What observable outcome would prove this repair actually works?
Explanation
Correct Answer
For West Auditorium, the decisive mechanism is RADIUS authorization timeout. Authentication server reachability and retry order influence network-admission decisions. Block the primary in a lab and verify configured fallback behavior supplies measurable, case-relevant evidence that the intended behavior actually occurs.
Incorrect Answers
This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication server reachability and retry order influence network-admission decisions
This is relevant to Dynamic VLAN on wired port, where dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication server reachability and retry order influence network-admission decisions
This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication server reachability and retry order influence network-admission decisions
