問題3
Given: A WLAN consultant has just finished installing a WLAN controller with 15 controller-based APs. Two SSIDs with separate VLANs are configured for this network, and both VLANs are configured to use the same RADIUS server. The SSIDs are configured as follows:
SSID Blue - VLAN 10 - Lightweight EAP (LEAP) authentication - CCMP cipher suite SSID Red - VLAN 20 - PEAPv0/EAP-TLS authentication - TKIP cipher suite The consultant's computer can successfully authenticate and browse the Internet when using the Blue SSID.
The same computer cannot authenticate when using the Red SSID.
What is a possible cause of the problem?

問題5
Given: Mary has just finished troubleshooting an 802.11g network performance problem using a laptop-based WLAN protocol analyzer. The wireless network implements 802.1X/PEAP and the client devices are authenticating properly. When Mary disables the WLAN protocol analyzer, configures her laptop for PEAP authentication, and then tries to connect to the wireless network, she is unsuccessful. Before using the WLAN protocol analyzer, Mary's laptop connected to the network without any problems.
What statement indicates why Mary cannot access the network from her laptop computer?
