Question 1080
During a privileged access assessment at Atlas Scientific, engineers say that they resolved this finding: An 802.1X laptop authenticates successfully but receives the wrong VLAN due to an authorization profile mismatch. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
The laptop receives its assigned VLAN and the policy hit is visible in ISE logs. This is the decisive evidence for the original problem: An 802.1X laptop authenticates successfully but receives the wrong VLAN due to an authorization profile mismatch. It verifies that the intended corrective control—Inspect ISE policy set conditions and the RADIUS authorization result delivered to the switch—works in the relevant environment; a completed change ticket alone would not prove the outcome at Atlas Scientific.
Incorrect Answers
The known printer reaches only its required service while unknown MAC addresses remain restricted. This would be relevant evidence for a different failure: A printer lacks an 802.1X supplicant but must join a restricted service network, usually addressed by Use Cisco ISE MAC Authentication Bypass with constrained authorization and device profiling. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: The laptop receives its assigned VLAN and the policy hit is visible in ISE logs.
802.1X requests reach the new ISE node and successful authentications are logged. This would be relevant evidence for a different failure: The switch sends RADIUS to an old ISE address and all port authentication times out after a server migration, usually addressed by Update the network device AAA server configuration and confirm reachability and shared secret. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: The laptop receives its assigned VLAN and the policy hit is visible in ISE logs.
A spoofed unknown endpoint cannot obtain privileged user-network resources. This would be relevant evidence for a different failure: An access policy grants privileged access based only on a claimed device MAC address, usually addressed by Combine MAB with profiling, segmentation, and stronger identity controls where possible. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: The laptop receives its assigned VLAN and the policy hit is visible in ISE logs.
