Question 150
An ISE administrator troubleshoots the following: A regulated lab requires all regular user traffic denied until an endpoint has successfully completed authentication; the current open authorization permits unverified traffic. What should the team change before declaring this work complete?
Explanation
Correct Answer
Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. This is appropriate because closed mode restricts ordinary data access before a valid authentication result, enforcing the port's intended admission barrier. It should be verified by this evidence: An unrecognized laptop cannot reach protected destinations, and a managed authenticated laptop obtains its authorized access.

Those technical conditions are not interchangeable.
