問題文
A capture shows a laptop sending a data frame to an access point before it has completed any 802.11 management exchange with that unit. The access point answers with a single management frame of its own. What does that frame do to the state of the laptop?
選択肢
- It is a frame that takes the association away alone so the laptop can send its association request once more.
- It is a frame that always takes the authentication away so the laptop has to begin again from the low level exchange.
- It is a frame that carries the rates of the unit so the laptop can send the same frame again at a rate they share.
- It is a frame that grants an identifier for the association so the data frame is then accepted by the unit.
