Which statement about when you configure FlexConnect APs and you want to set up Cisco Centralized Key Management fast roaming is true?
A. FlexConnect groups are required for Cisco Centralized Key Management fast roaming to work with FlexConnect access points.
B. APs that are in the same FlexConnect group but associated to different WLCs support Cisco Centralized Key Management.
C. Cisco Centralized Key Management fast roaming among FlexConnect and non- FlexConnect access points is supported.
D. The FlexConnect access point must be in standalone mode to support Cisco Centralized Key Management.
Correct answer is A.
“Fast roaming works only if the APs are in the same FlexConnect group for APs in FlexConnect mode, 802.11r”
“When using FlexConnect groups for OKC or CCKM, the PMK-cache is shared only across the access points that are part of the same FlexConnect group and are associated to the same controller. If the access points are in the same FlexConnect group but are associated to different controllers that are part of the same mobility group, the PMK cache is not updated and CCKM roaming will fail but OKC roaming will still work”
