Flooding means that the switch sends the incoming frame to all occupied and active ports (except for the one from which it was received In forwarding, it first looks up the destination address in the MAC Address Table. It then forwards the frame to that specific port.

duplex mismatch. Cisco wireless design separates RF behavior, client authentication, encryption, AP operating mode, and controller management. A WLC centralizes WLAN configuration and AP control, while lightweight APs use CAPWAP to register and exchange control/data information with the controller. Security choices such as WPA2/AES and WPA3/SAE are not interchangeable with older mechanisms such as WEP, TKIP, or RC4. RF questions also depend on channel planning: adjacent cells should avoid overlapping channels, and 5-GHz preference features reduce congestion in the 2.4-GHz band. The incorrect options generally confuse AP mode, authentication, encryption, or controller responsibilities. Cisco CCNA 200-301 v1.1 includes these items because wireless failures often come from using the right-looking feature in the wrong part of the WLAN design. The selected answer is the Cisco-consistent configuration or behavior for this wireless scenario.
