Exam 300-715 topic 1 question 144 discussion

The correct answers are access-challenge and access-accept. The RADIUS server can send four types of responses to the NAS: Access-Accept: The user is authenticated and authorized to access the requested resources. Access-Reject: The user is not authenticated or authorized to access the requested resources. Access-Challenge: The RADIUS server needs more information from the user before it can make a decision. Access-Timeout: The RADIUS server did not respond to the NAS's request in a timely manner. The other options are not valid responses from the RADIUS server to the NAS.
