In the frame decode shown, there are two sets of supported data rates. 1, 2, 5.5, and 11 Mbps are all
shown as “basic” data rates, and 6, 9, 12, 18, 24, 36, 48, and 54 Mbps are shown simply as supported data
rates.

What is true of “basic” data rates in this context?

A.
The AP requires all client stations to support Basic rates in order to associate to its BSS.

B.
The highest data rate set to Basic is automatically used to send broadcast traffic such as Beacon
frames.

C.
Basic rates are optional data rates for the BSS, often used for assuring connectivity for legacy stations.

D.
Basic rates are only used for multicast traffic, and do not affect unicast traffic.

E.
Basic rates are defined in an AP’s service set to specify mandatory data rates for all retry frames.
