A Linux-based RADIUS server will be used for authentication. What device in the bridge implementation acts as the 802.11X Authenticator?

• A.The Ethernet switch
• B.The RADIUS server
• C.The root bridge
• D.All non-root bridges

When performing a site survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with five floors, what aspect should you, as the site surveyor, keep in mind?

• A.The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.
• B.The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible.
• C.The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.
• D.The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration.

Lynne runs a small hotel, and as a value added for his customers he has implemented a Wi-Fi hotspot.
Lynne has read news articles about how hackers wait at hotspots trying to take advantage of unsuspecting
users. He wants to avoid this problem at his hotel.
What is an efficient and practical step that Lynne can take to decrease the likelihood of active attacks on
his customers' wireless computers?

• A.Implement Network Access Control (NAC) and require antivirus and firewall software along with OS
  patches.
• B.Enable station-to-station traffic blocking by the access points in the hotel.
• C.Implement an SSL VPN in the WLAN controller that initiates after HTTPS login.
• D.Require EAP_FAST authentication and provide customers with a username/password on their receipt.

You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.
What common spectrum analyzer view should you use for this analysis?

• A.APs
• B.Clients
• C.Waterfall/Spectrogram
• D.Real-time FFT
