PW0-105 · Question #124
In an 802.11n 2.4 GHz BSS, what prevents each station from using the full network bandwidth (e.g. 130 Mbps) when multiple clients are actively exchanging data with the AP? (Choose two)
The correct answer is C. The DCF and EDCA coordination functions require backoff algorithms D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment. See the full explanation below for the reasoning.

Options
- ARadio receiver hardware cannot process data as quickly as it can be transmitted.
- BHalf of the bandwidth is allocated to uplink traffic and half to downlink traffic.
- CThe DCF and EDCA coordination functions require backoff algorithms
- DWLAN devices cannot detect collisions and must receive positive frame acknowledgment.
- EWLANs rely on the CSMA/CD protocol and must wait a collision detection period after each frame
