Exam 300-430 topic 1 question 97 discussion

This is a classic Cisco putting ambiguous questions that will have multiple right answers. The IP address response is incorrect and can be ruled out because DHCP occurs after a 802.1x authentication when the client is in the run state (assuming no WebAuth). That leaves an invalid authentication policy on the authenticator which it could be if they didn't define the AAA settings properly. It could be an account lockout as the user will not be notified if it's locked. The final option is an invalid authentication policy on the authentication server. All three of these could be right but I would choose the user account is locked because it says you are troubleshooting a user specific issue. The misconfigured authenticator or authentication server would have widespread problems affecting multiple users wheras the individual user account being locked would explain a user specific problem.

Wrong, correct answer is A

I suppose this answer

The issue is likely caused by the user's Active Directory (AD) account being locked out after multiple failed authentication attempts. When a user enters incorrect credentials multiple times, many organizations have policies in place to lock the account temporarily or until an administrator unlocks it. This prevents unauthorized access but can also cause legitimate users to be locked out if they mistype their credentials.

Provided answer is correct

I think it may be A. "If the supplicant submits an invalid credential or is not allowed to access the network for policy reasons, the authentication server returns a RADIUS Access-Reject message with an encapsulated EAP-Failure message"
