Show Suggested Answer

Suggested Answer: A

RTS is not a valid acknowledgement frame. RTS stands for Request To Send, and it is a control frame that is used to initiate an RTS/CTS exchange before sending a data frame. The purpose of an RTS/CTS exchange is to reserve the medium for a data transmission and avoid collisions with hidden nodes. An acknowledgement frame is a control frame that is used to confirm the successful reception of a data frame or a block of data frames. The valid acknowledgement frames are CTS (Clear To Send), Ack (Acknowledgement), and Block Ack (Block Acknowledgement) .

RTS? What is this, a game of charades? I thought we were talking about networking protocols, not mime.

CTS is for Clear-to-Send, not an acknowledgement. Whoever came up with these options is just messing with us.
