Actual exam question from Cisco's 300-425

Question #: 88
Topic #: 1

APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place. What is the cause of the issue regarding the FlexConnect APs?

A. They do not support 802.11r FT.
B. They must be added into AP groups along with a common RF profile.
C. They must be in a FlexConnect group to support 802.11r FT.
D. They must be added to AP groups to support fast roaming methods.

C is right In a FlexConnect Deployment scenario, 802.11r BSS FT roaming is supported between APs within the same FlexConnect group. A would be applicable if it was local authentication aswell. but there is no mention of it.

"802.11r Fast Transition is not working as expected, like on local mode AP" So it was working before the change to FC, then put the AP in a FC group.

Selected Answer: C

In 8.1 and earlier releases, this feature is not supported on access points in FlexConnect mode. In Release 8.2, this restriction is removed.802.11r fast roaming works only if the APs are in the same FlexConnect group. https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/content/dam/en/us/td/docs/wireless/controller/technotes/80211r-ft/b-80211r-dg.html.xml#:~:text=802.11r%20fast%20roaming%20works%20only%20if%20the%20APs,standalone%20mode.%20EAP%20LEAP%20method%20is%20not%20supported.
