What statement about 802.11 WLAN bridges is true?

• A.WLAN bridges must use a channel with acceptable SNR at both transceivers to maintain the desired data rate bi-directionally
• B.WLAN bridges must be implemented such that no interference occurs on the channel anywhere between the two endpoints used to establish the bridge
• C.WLAN bridges only work in the 2.4 GHz frequency band and they support only SISO communications
• D.WLAN bridges may support MIMO communication, but only if used in the GHz frequency band

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.A virtual cell single channel network has been implemented
• B.The beacons are from an IBSS instead of a BSS
• C.Three APs still share the same default configuration.
• D.A single AP supports multiple BSSs with different SSIDs

What fact is true regarding controllers and Aps in a split-MAC architecture?

• A.Management and data frames must be processed locally by the AP, while control frames are sent to the controller
• B.With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator
• C.An IP tunnel is established between the AP and controller for AP management and control functions
• D.Using centralized data forwarding, frames leaving the Aps are never tagged Ethernet frames with VLAN identifiers
