Exam 220-1102 topic 1 question 442 discussion

Out of the listed protocols, the one that supports fast roaming between networks is: C. WPA2 (Wi-Fi Protected Access 2) Here's why: Fast roaming: WPA2 includes a feature called 802.11r (Fast Roaming) that allows a device to seamlessly switch between access points on the same network without losing connection or experiencing significant delays. This is achieved by maintaining a connection with both the old and new access points during the handover process. Other protocols: - WEP (A): Weak encryption standard without fast roaming capabilities. - WPA (B): Similar to WEP in terms of security strength and lacking fast roaming support. - LEAP (D) and PEAP (E): Authentication protocols, not directly related to network roaming mechanisms.

C 802.11r fast roaming is not supported if the client uses Over-the-DS preauthentication in standalone mode. EAP LEAP method is not supported. Fast roaming WiFi, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another.

802.11r fast roaming is not supported if the client uses Over-the-DS preauthentication in standalone mode. EAP LEAP method is not supported. C- my Answer

My first thought was WPA2, then ChatGPT backed that up: The protocol that supports fast roaming between networks is: C. WPA2 WPA2 (Wi-Fi Protected Access 2) includes a feature called Fast BSS Transition (FT), which enables fast roaming between access points in a wireless network. This feature allows a client device to switch from one access point to another seamlessly without reauthentication, providing a smoother transition and minimizing disruptions in connectivity. Options A (WEP), B (WPA), D (LEAP), and E (PEAP) do not natively support fast roaming to the same extent as WPA2, making WPA2 the most suitable choice for environments where seamless roaming is a priority.
