問題4
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'sbeacon 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?

問題7
As a consultant, you have been hired by ABC Company to implement an outdoor WLAN connection between two buildings that are 2 kilometers (1.24 miles) from each other, with no obstructions in between.
Your first required objective is to create a point-to-point link between the two buildings within the local regulatory body's 800 mW EIRP maximum.
Your second required objective is to provide an industry-standard security solution capable of supporting mutual authentication.
As an optional objective, you must minimize the amount of interference from, and to, nearby WLAN networks.
You install an OFDM wireless bridge at each building, configuring one in root mode and the other in non-root mode. You set each radio for 100 mW (20 dBm) and attach 9 dBi omni- directional antennas to both. You configure the network for WPA2-Enterprise with
PEAPv0/EAP-MSCHAPv2 authentication.
Which statement is true about the solution you chose to deploy?
