A wireless engineer must improve the roaming performance of the handheld mobile video units. Which feature must be enabled in the controller?
The correct answer is D. FT. FT (Fast Transition), defined in IEEE 802.11r, is the correct feature to enable for improved roaming performance. Handheld mobile video units move frequently and require fast, seamless roaming to avoid video freeze or packet loss. 802.11r pre-authenticates clients with target…

Explanation
FT (Fast Transition), defined in IEEE 802.11r, is the correct feature to enable for improved roaming performance. Handheld mobile video units move frequently and require fast, seamless roaming to avoid video freeze or packet loss. 802.11r pre-authenticates clients with target APs before the roam occurs, dramatically reducing roaming latency (from hundreds of milliseconds to under 50ms). HT (High Throughput) improves speed but not roaming. AVC (Application Visibility and Control) classifies traffic. PMF (Protected Management Frames) improves security, not roaming speed.
