Question 1090
At Seabright Municipal Works, a team reports that it corrected the following problem affecting public service networks and records: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
Valid employees receive enterprise access and failed or guest sessions receive only restricted access. This is the decisive evidence for the original problem: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. It verifies that the intended corrective control—Correct authentication method ordering and authorization fallback conditions—works in the relevant environment; a completed change ticket alone would not prove the outcome at Seabright Municipal Works.
Incorrect Answers
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 Seabright Municipal Works was resolved. The specific required evidence is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access.
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 Seabright Municipal Works was resolved. The specific required evidence is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access.
The laptop receives its assigned VLAN and the policy hit is visible in ISE logs. This would be relevant evidence for a different failure: An 802.1X laptop authenticates successfully but receives the wrong VLAN due to an authorization profile mismatch, usually addressed by Inspect ISE policy set conditions and the RADIUS authorization result delivered to the switch. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access.
