What is a difference between an Infrastructure Basic Service Set (BSS) network and an Ad Hoc network?

A. In an Ad Hoc network, only one WLAN controller is used. A BSS allows multiple WLAN controllers to be connected together to form a mobility domain.

B. An Ad Hoc network allows only legacy security options such as WEP. A BSS allows the creation of a robust security network (RSN) using security methods such as WPA2- Personal.

C. A BSS is recommended for enterprise WLANs, while Ad Hoc deployments are recommended for small and medium businesses.

D. In a BSS, an access point is used for connectivity to the wired network infrastructure. In an Ad Hoc network, client stations communicate directly with each other.

Wi-Fi certified network devices can operate in what frequency band(s)?

B. 900 MHz, 2.4 GHz, and 5 GHz

C. 2.4 GHz and 5 GHz

D. 5.8 GHz only

What type of protection does a lightning arrestor provide to a Wi-Fi system?

A. Protection from direct lightning strikes

B. Prevention of direct lightning strikes

C. Redirection of transient current due to nearby lightning strikes

D. Absorption of the energy induced by direct lightning strikes

Given: In Single-Channel Architecture (SCA) systems, multiple access points can use the same BSSID. This feature allows for the creation of a network-wide virtual access point that can be applied across multiple physical access points operating on the same channel.

What benefit does this solution offer?

A. The virtual AP can be managed using a WIPS platform

B. Transmissions travel farther since they are repeated by other APs

C. A wider variety of available security mechanisms are available

D. Client stations do not have to make roaming decisions

What is the most likely cause of low throughput on a hotel's guest network?

A. The 1.5 Mbps Internet connection is creating a bottleneck for the Wi-Fi users.

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.

Identify the strongest passphrase-based security mechanism for 802.11 wireless networks.

A. TKIP

B. WPA-PSK

C. WPA2-Personal

D. RC4

E. WEP

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.
