B. The user's laptop does not have 54 Mbps data rate enabled.

C. The strong security methods used with public access networks often cause low throughput.

D. The user is too close to the servicing access point.

Virtual Private Network (VPN) solutions are often used in conjunction with Wi-Fi networks for what purpose?

A. Endpoint security for travelling users connected to unsecure Wi-Fi hot-spots

B. Validating user identity when using 802.1X/EAP security

C. Capturing and analyzing wireless network frames

D. Managing access points that are connected to WLAN controllers

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.

ABC Company's wireless network is configured to hide the SSID in beacons, and allows connectivity only to approved MAC addresses.
