Which statements accurately describe IEEE 802.11 EDCA collision handling in a WMM-compliant infrastructure WLAN? (Choose 2)
The correct answer is A. When frames collide within a QoS STA, data frames from lower priority ACs behave (as it relates B. Collisions between contending EDCAFs within a QoS STA are resolved within the QoS STA. See the full explanation below for the reasoning.
