Question 7

Refer to the exhibit.

Which statement about the join process of the access point is true?

A. The controller rejected most of the discovery requests from the AP because they were not received on the management interface subnet. The AP failed to join the controller.

B. The time on the controller is outside of the certificates validity time interval, so the join phase failed.

C. The AP failed to join because the self-signed certificate of the AP on the controller was not correct.

D. The AP moved from this controller to its primary controller.

E. The AP successfully joined the controller.

Correct Answer: A

C. top-down

D. divide and conquer

E. follow the path

Correct Answer: D

Question 9

Which statement about the join process of the access point is true?
Refer to the exhibit.

A. The AP failed to join because the MAC address of the AP was not correct on the controller.

B. The time on the controller is outside of the certificates validity time interval, so the join phase failed.

C. The controller rejected all discovery requests from the AP because they were not received on the management interface subnet.

D. The AP moved from this controller to its primary controller.

E. The AP successfully joined the controller.

Correct Answer: A
