TestOut Module 9: Wireless Networking Quiz

What is the definition of a Basic Service Set in wireless networking?

• The LAN that connects multiple APs and BSSs together

• The smallest unit of a wireless network

• A wireless topology that connects to all APs through wired links

• A security certification program that was developed by the Wi-Fi Alliance

What does the acronym 'SSID' stand for?

• Service Set Identifier

• Secure Signal Identification

• Service Signal Identifier

• Secure Service Internet Device

What is the purpose of Wi-Fi Protected Access (WPA)?

• It is a 48-bit value that identifies an AP in an infrastructure network

• It is an encryption that uses 128-, 192-, or 256-bit key lengths

• It is a security certification program that ensures secure wireless signals between devices

• It is the name of the wireless network displayed to a client

What is the role of a Distribution System in a wireless network?

• It is a set of stations configured in ad hoc mode

• It is an authentication method that requires clients to provide a MAC address

• It is the LAN that connects multiple APs (and BSSs) together

• It is a wireless topology that connects to all APs through wired links but contains very little embedded intelligence

Which of the following best describes Roaming in the context of wireless networking?

• The ability of devices to connect from one access point to another while maintaining connection to the same network

• A wireless network that works in peer-to-peer mode without an access point

• A case-sensitive name that specifies a service set (network) to which a wireless device can join or connect to

• Bridges used to connect wired or wireless networks

What is shared key authentication?

• An antenna that disperses the radio frequency wave in an equal 360-degree pattern

• An authentication method that uses usernames and passwords, certificates, or devices such as smart cards to authenticate wireless clients

• An authentication method that configures clients and access points with a shared key (passphrase)

• The point at which all the available bandwidth on a connection has achieved maximum capacity and cannot pass any more data through the connection

What is the purpose of a directional antenna?

• To create signal interference intentionally by an attacker

• To disperse the radio frequency wave in an equal 360-degree pattern

• To create a narrow, focused signal, which increases the signal strength and transmission distance

• To pass radio waves through objects of different densities, causing the signal to bend or change speeds

What does packet sniffing refer to?

• The point at which bandwidth utilization for the device is close to 100%

• The interception and decoding of wireless transmissions

• The electromagnetic field generated by a network cable or device that can be manipulated to eavesdrop or steal data

• An attack that spoofs the MAC address and then disconnects the device from the wireless network

What is the result of interference in a wireless network?

• The signal passes through objects and loses power

• The wireless signal sent by APs and other wireless devices corrupts or destroys because normal communications are made impossible

• The signal bends or changes speed when passing through objects of different densities

• The signal is intentionally jammed by an attacker to make the network impossible to use

What is Bluetooth primarily used for?

• To create intentional signal interference to disrupt a wireless network

• For short-range wireless interconnection, allowing devices to communicate within a PAN of close proximity

• To intercept and decode wireless transmissions

• To disperse the radio frequency wave in an equal 360-degree pattern
