Q: 19
When an ACK frame is not received by the transmitting STA, what is assumed?

Probably C. Had a similar question in practice tests and the official guide covers this in the basic ACK mechanism.
Its C, but if the question gave a specific scenario like 802.11w protecting management frames that could change things. Here though, missing ACK means assume not delivered and retransmit (unless question states otherwise).
Its C, had something like this in a mock. If no ACK comes back, 802.11 expects the frame was lost and will trigger a retransmit. Pretty sure that's standard wireless behavior.
I get where you’re coming from, but it’s C. In 802.11, if the sender doesn’t get an ACK, it assumes the frame didn’t make it and triggers a retransmit. B seems logical at first but without an ACK the protocol can't just assume delivery. Pretty sure about this but let me know if I’m off.
C is the best fit. In 802.11, missing the ACK means the transmitter assumes the frame wasn’t received and must retransmit, part of making wireless reliable. B trips some people up, but delivery isn’t assumed without that ACK. Pretty sure about this, open to correction if I’m missing a detail.
C/D? Both seem possible if you think about retransmissions or offline status.
B . Sometimes the frame actually gets through but the ACK is missed, so I think B could fit here even if it's a bit of a trick option. Don’t see mention of retransmission requirements in the question.
B tbh
