Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 238

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?

Answer options

• 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.

Correct answer: C

Explanation

The correct answer is C because FlexConnect APs require membership in a FlexConnect group to support 802.11r Fast Transition. Option A is incorrect as FlexConnect APs can support 802.11r FT if configured properly. Option B is not relevant to the specific requirement for 802.11r FT, and Option D is also incorrect because AP groups alone do not enable the required support without the FlexConnect group.
