Question 230
During a Cisco ISE access-control troubleshooting session, the team observes: A visitor's contract is terminated early but their sponsored guest account remains within its ordinary validity period and the security team must end access immediately. Which Cisco ISE action most directly resolves the observed problem?
Explanation
Correct Answer
The underlying cause is: A future expiration timestamp alone does not terminate an already authorized guest session; disabling or revoking account access must be reflected on the NAD. The correct response is: Disable the visitor identity and apply a supported session termination or reauthorization process for active access sessions. Confirm by checking: The visitor's old credentials no longer authenticate and an existing guest session loses access without waiting for the original expiry.
Incorrect Answers
That intervention addresses guest isolation from internal corporate resources, where Successful portal login authenticates the visitor but does not inherently restrict the final authorization profile to public Internet destinations. Here, the relevant failure is instead: A future expiration timestamp alone does not terminate an already authorized guest session; disabling or revoking account access must be reflected on the NAD.
That intervention addresses coa after completed guest portal login, where An existing guest network session needs a supported authorization refresh such as RADIUS CoA for its final access result to replace the redirection permissions. In this question the necessary remedy is “Disable the visitor identity and apply a supported session termination or reauthorization process for active access sessions”, which this alternative does not provide.
That intervention addresses guest portal identity source selection, where Portal authentication uses the identity source or source sequence selected for that portal, which can be separate from corporate employee authentication policies. The observed condition is a visitor's contract is terminated early but their sponsored guest account remains within its ordinary validity period and the security team must end access immediately; this mechanism addresses another problem.
