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

B.
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.

C.
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.

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