A network administrator creates an employee WLAN on an Aruba solution that uses WLAN WPA2-Enterprise security and an external RADIUS server. When the administrator tests the WLAN, the test client receives limited connectivity and cannot access any resources, but the RADIUS server shows that the user authenticated successfully. What should the administrator check as a possible source of this issue?
A. the connectivity between the AP that the client is associated to and the MC
B. the firewall role and policy that apply to this user
C. the certificate on the RADIUS server
D. the connectivity between the Master Controller (MC) for the client and the RADIUS server
