Which of the following does a client station do to indicate that it is using power save mode?
  1. It transmits a frame to the access point, with the Sleep field set to 1.
  2. It transmits a frame to the access point, with the Power Management field set to 1.
  3. The access point determines when the client station uses power save mode using DTIM.
  4. It does nothing. Power Save mode is set by default.
Explanation
Answer - B - The client station transmits a frame to the access point with the Power Management field set to 1.

Key Takeaway: When the client station transmits a frame with the Power Management field set to 1, it is enabling the Power Save mode. The DTIM only notifies clients to stay awake in preparation for a multicast or broadcast.
