Given: In ABC Company's branch office, there are three 802.11n access points serving 20 Wi-Fi clients for email, web browsing, and occasional file sharing. Some users sit at a picnic table outside the building during lunchtime and have complained that the network is slow and connectivity is intermittent during this period of time.
What is the most likely cause of the slow and intermittent connectivity?
A. The users experiencing connectivity problems are using WPA2-Personal, which has shorter range than 802.1X/EAP.
B. WLANs require visual line-of-sight, and only those clients that can see an AP through a window can connect.
C. The picnic tables are located at the edge of the effective range of Wi-Fi coverage.
D. The client laptops are using 802.11g radios that are not fully interoperable with 802.11n.
After successfully connecting to the Wi-Fi network in your hotel room, you launch a web browser on your laptop. Instead of opening your homepage, it directs you to a hotel- branded page that asks for your name, room number, and a secret key. What has most likely happened?
A. You are the victim of a phishing attack, should not provide the information, and should call the front desk for help.
B. Every room in the hotel has its own access point, and entering the room number and key confirms connectivity to the correct AP.
C. The access point is out of connections and you must enter your room number and code to be added to the hotel's Access Request Queue (ARQ) to obtain the next available connection.
D. The hotel is using a captive portal to provide guest connectivity while keeping non-guest users off the wireless network.
