A.Before the client adapter WEP key is generated， all wireless infrastructure devices （such as access points， servers， etc.） must be properly configured for LEAP authentication.
B.The client adapter WEP key should be generated by the AP and forwarded to the client adapter efore the client adapter can establish communication with the wireless network.
C.In infrastructure mode the client adapter WEP key must match the WEP key used by the access point. In ad hoc mode all client WEP keys within the wireless network must match each other.
D.The client adapter WEP key should be generated by the authentication server and forwarded to the client adapter before the client adapter can establish communication with the wireless network.
E.None of the other alternatives apply

A.to provide access to proprietary Cisco IOS software code in order to expand the number of vendors writing wireless code
B.to provide Cisco engineers with the opportunity to certify that any wireless devices that are made by third parties are compatible with Cisco wireless products
C.to provide customers with a broad range of WLAN client devices that have been tested for interoperability with Cisco Aironet innovations
D.to provide third parties with Cisco hardware in order to encourage the development of radical innovation in the area of wireless

A.Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending BPDUs with a superior root bridge parameter， but traffic is still forwarded across the ports.
B.Interfaces FastEthernet3/1 and FastEthernet3/2 are candidate for becoming the STP root port， but neither can realize that role until BPDUs with a superior root bridge parameter are no longer received on at least one of the interfaces.
C.Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending BPDUs with a superior root bridge parameter and no traffic is forwarded across the ports.Once inaccurate BPDUs have been stopped， the interfaces automatically recover and resume normal operation.
D.Devices connected to interfaces FastEthernet3/1 and FastEthernet3/2 are sending BPDUs with a superior root bridge parameter and no traffic is forwarded across the ports.Once inaccurate BPDUs have been stopped， the interfaces will need to be administratively shut down， and brought back up， to resume normal operation.

A.VLAN 200 carries traffic from promiscuous ports to isolated， community， and other promiscuous ports in the same VLAN. VLAN 202 carries traffic between community ports and to promiscuous ports.
B.VLAN 200 carries traffic from promiscuous ports to isolated， community， and other promiscuous ports in the same VLAN. VLAN 202 carries traffic from isolated ports to a promiscuous port.
C.VLAN 202 carries traffic from promiscuous ports to isolated， community， and other promiscuous ports in the same VLAN. VLAN 200 carries traffic from isolated ports to a promiscuous port.
D.VLAN 202 carries traffic from promiscuous ports to isolated， community， and other promiscuous ports in the same VLAN. VLAN 200 carries traffic between community ports and to promiscuous ports.

A.Place unused ports in a common VLAN.
B.Implement private VLANs.
C.Implement DHCP snooping.
D.Implement port security.
E.Implement VLAN access maps.
