300-365 Question #158: Real Exam Question with Answer & Explanation
The correct answer is A: FlexConnect groups. FlexConnect groups enable fast roaming with Cisco Centralized Key Manager by allowing APs in the same group to share PMK cache, avoiding full reauthentication during roam events.
Question
You plan to use Cisco Centralized Key Manager fast roaming with FlexConnect APs. Which configuration do you apply to minimize delays for real-time traffic while roaming?
Options
- AFlexConnect groups
- BFlexConnect local authentication
- CFlexConnect AVCs
- DFlexConnect centralized authentication
Explanation
FlexConnect groups enable fast roaming with Cisco Centralized Key Manager by allowing APs in the same group to share PMK cache, avoiding full reauthentication during roam events.
Common mistakes.
- B. FlexConnect local authentication offloads 802.1X authentication to the branch when the WAN is down but does not provide the shared key caching needed for fast roaming.
- C. FlexConnect AVCs (Application Visibility and Control) enforce per-application QoS and access policies but have no role in managing roaming key handoffs.
- D. FlexConnect centralized authentication sends client credentials back to the WLC for processing, which increases latency on each roam and is the opposite of what is needed to minimize delay.
