Question 440
At Learning Commons, a newly deployed employee switchport is connected but a laptop stays in an unauthorized port state. Which postchange observation is the strongest evidence of correct operation?
Explanation
Correct Answer
For Learning Commons, the decisive mechanism is Wired 802.1X port access. 802.1X authorizes port traffic through EAPOL and the authentication server decision. Connect a managed laptop and verify authorized access only after authentication supplies measurable, case-relevant evidence that the intended behavior actually occurs.
Incorrect Answers
This is relevant to RADIUS accounting for audit, where aAA accounting tracks session use separately from authentication and authorization In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1X authorizes port traffic through EAPOL and the authentication server decision
This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1X authorizes port traffic through EAPOL and the authentication server decision
This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1X authorizes port traffic through EAPOL and the authentication server decision
