What statement about the IEEE 802.11-2016 QoS facility is true?

C is the right one here. EDCA doesn't block Best Effort completely when Voice frames are waiting, it just gives Voice a better chance to win channel contention. B is a common trap but isn't how Wi-Fi QoS actually works. Pretty sure about this, but open if anyone sees it differently.
Probably C. B looks tempting but Voice queue doesn't fully block Best Effort in practice, so statistical edge fits better here.

C imo
Nah pretty sure it's B, the question feels like it's trapping folks on Voice queue rules.
C makes sense since QoS in 802.11 uses EDCA to give high priority traffic better odds, not guarantees. Option B is a trap because best effort isn't totally blocked by voice traffic. Pretty sure about this, but open to other views!
C , D is tricky but it's not about queue mapping, just the statistical edge from EDCA.
My pick: C. EDCA just gives statistical priority for high-priority queues, not absolute control. The rest aren't accurate here afaik.

Its C, statistical advantage is how 802.11 QoS works. Voice and Video get better contention values, but nothing gets blocked fully. Pretty sure about this but open if anyone's seen otherwise.
Be respectful. No spam.
