Regarding the guidelines for using MFP, under what circumstances will a client without Cisco Compatible Extensions v5 be able to associate to a WLAN?
A. WPA2 is enabled with TKIP or AES.
B. AAA override is configured for the WLAN.
C. The DHCP Required box is unchecked.
D. Client MFP id disabled or optional.
I agree, should be D
Should be D: Client MFP is disabled or optional.
“Non-CCXv5 clients may associate to a WLAN if client MFP is disabled or optional.”
