Given: ABC Company has recently installed its first access point. The access point is an ERP unit, and both ERP and HR-DSSS client stations will be used on the wireless network simultaneously. The network administrator has appropriately configured the access point and all of the company’s HR-DSSS wireless client stations to use short preambles for CCK transmissions. A visitor begins using a Personal Data Assistant (PDA) with an integrated HR-DSSS radio configured for use of long preambles on ABC’s wireless network.

Which statement describes what the network administrator will see with a wireless protocol analyzer?

A.
Once the visitor’s PDA is associated to the access point, all HR-DSSS stations associated to the access point will begin using long preambles.

B.
The visitor’s PDA will not be able to associate to the wireless network, and it will cause significant interference for other wireless stations.

C.
The visitor’s PDA will communicate with the access point using long preambles, and the access point will communicate with all other client stations using short preambles.

D.
The visitor’s PDA will associate to the access point using MMPDUs with long preambles, but then begin sending Data frames using short preambles since Data frames cannot use long preambles.
