A customer wants the APs in the CEO’s office to have different usernames and passwords for administrative support than the other APs deployed throughout the facility. Which feature must be enabled on the WLC and APs to achieve this goal?
A. local management users
B. HTTPS access
C. 802.1X supplicant credentials
D. override global credentials
I think the answer is D
“Select the Over-ride Global Credentials check box to prevent this access point from inheriting the global username,
password, and enable password from the controller. The default value is unselected.
In the Username, Password, and Enable Password text boxes, enter the unique username, password, and enable
password that you want to assign to this access point”
