Question 490
An ISE administrator troubleshoots the following: A corporate BYOD wireless client lands on the ISE registration portal but cannot download its supplicant configuration because the initial guest ACL blocks the required onboarding endpoints. Which governance step most directly targets the root cause?
Explanation
Correct Answer
Run onboarding with the actual limited-access ACL and DNS view used by new devices. This control addresses recurrence of the observed failure. The governing behavior is: Native supplicant provisioning depends on reachable portal and certificate services before the final 802.1X identity exists. The ongoing acceptance check remains: The pilot device completes native supplicant setup while unauthorized internal applications remain blocked during enrollment.
Incorrect Answers
Run onboarding with the actual limited-access ACL and DNS view used by new devices. The offered choice instead concerns a different principle: Renew or reprovision a valid approved certificate and verify the permitted trust chain and identity mapping before reauthorizing the device. Those technical conditions are not interchangeable.
Run onboarding with the actual limited-access ACL and DNS view used by new devices. The offered choice instead concerns a different principle: Maintain OS-specific BYOD enrollment tests as mobile versions change. Those technical conditions are not interchangeable.
Run onboarding with the actual limited-access ACL and DNS view used by new devices. The offered choice instead concerns a different principle: the My Devices registration quota limits how many personal devices an employee may enroll; this is independent of general wireless capacity. Those technical conditions are not interchangeable.
