Question #37

Given: Your network consists of HT and ERP access points, and you are implementing VoWiFi with support for U-APSD.
When an ERP handset operating in WMM Power Save mode with a ReceiveDTIMs parameter of TRUE receives a Beacon containing a DTIM indicating queued broadcast traffic, what task is the handset required to perform?

A. The handset is to remain awake to receive the broadcast frame(s) following the Beacon that contains the DTIM.

B. The handset must broadcast a CTS-to-Self frame indicating the station's need to control the medium long enough to receive all of the broadcast frames.

C. The handset must send a PS-Poll frame to the access point for every broadcast frame it receives with the More Data bit set to one.

D. The handset must arbitrate for the medium and immediately issue an RTS directed to the access point with the NAV set to a value of 32,768.
