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

My pick: C. EDCA just gives statistical priority for high-priority queues, not absolute control. The rest aren't accurate here afaik.
Its C, the key is that QoS in 802.11 uses EDCA which only gives higher priority traffic a better *chance* at getting on the air first. It's not guaranteed like option B suggests, and D is a distractor since there are four access categories, not eight transmit queues. Pretty sure this lines up with most CWNA resources.
Option D. I've seen practice exams that talk about the 802.1p priorities mapping directly to transmit queues so that's what I'd pick.
Probably C, I had something like this in a mock and it matches the EDCA mechanism.
Be respectful. No spam.
