Your companyhas many client devices, some that support WEP, some that support WPA, and some that support WPA2. The client devices that support only WEP can be firmware upgraded to support the TKIP wireless security protocol. As the wireless administrator at Your company, it is your responsibility to provide the strongest industry standard layer-2 security possible while applying a reliable solution for all devices.

You are a network engineer for your company. Your company wants you to establish an outdoor WLAN connection between two buildings that are 2 kilometers (1.24 miles) apart. Your first required goal is to create a point-to-point link between the two buildings within FCC regulations. Secondly, you need to provide an industry-standard security solution capable of supporting mutual authentication. Protecting your wireless bridges from environmental elements such as windblown dust, rain, and splashing water could be done as an optional goal.

You proceed by installing an 802.11b wireless bridge at each building, configuring one in root mode and the other in non-root mode. You then configure each radio for 1 watt (+30 dBm) and connect 9 dBi omni-directional antennas to both. You position each wireless bridge in a NEMA- compliant enclosure intended for outdoor use and configure them for 802.11i-compliant security features. Which statement in relation to the solution you chose to deploy is accurate?
