Which two Layer 2 security protocols are supported by 802.11r under the WLAN configuration? (Choose two.)
The correct answer is A. WPA2 E. Open. IEEE 802.11r (Fast BSS Transition) enables fast roaming by pre-negotiating security keys before a client fully reassociates with a new AP. On Cisco WLC WLAN configuration, 802.11r is supported with WPA2 (A) - which is the modern, secure standard using either PSK or 802.1x-based…

Explanation
IEEE 802.11r (Fast BSS Transition) enables fast roaming by pre-negotiating security keys before a client fully reassociates with a new AP. On Cisco WLC WLAN configuration, 802.11r is supported with WPA2 (A) - which is the modern, secure standard using either PSK or 802.1x-based authentication - and Open (E) security, where no Layer 2 encryption is applied. Static WEP (C) and WPA (D) are legacy or deprecated security methods not compatible with 802.11r's fast transition mechanisms. While 802.1x (B) is an authentication framework used within WPA2, it is not listed as a standalone Layer 2 security option in this context for 802.11r.
