As XYZ Company's wireless specialist, you have been asked to troubleshoot some unexpected frame patterns in a wireless protocol capture. Your peers explain that the network's beacon frames are inconsistent. That is, the BSSID is the same for all beacons, but the source address varies between three different addresses.
What network configuration would cause this beacon frame behavior?

A. Three APs still share the same default configuration.

B. A single AP supports multiple BSSs with different SSIDs

C. A virtual cell single channel network has been implemented

D. The beacons are from an IBSS instead of a BSS
