Exam 8: Wireless Security

Are network signals transmitted over radio waves in a fashion similar to the way your local radio station broadcasts?

Which organization is supported by wireless network device manufacturers and promoters, including Alvarion, Cisco Systems, ELAN, Intermec, Intersil, Raylink, and Wireless Central?

In CSMA/CA, is the backoff time determined by multiplying a predetermined slot-time by a random number?

By 2006, how many wireless devices are expected to be installed?

Radio frequencies are the range of frequencies above _____ kilohertz through which an electromagnetic signal can be radiated into space.

Many wireless network users are deploying Bluetooth devices because these devices do not rely on proprietary communications, particularly in the lower (and slower) 902-928 MHz range common to older wireless devices.

Is an access point usually a router or switch?

Does Mac OS X and Apples iMac, iBook, Powerbook G4, and Power Mac G4 computers come with built-in compatibility for 3COM WNICs and base stations (access points)?

What type of device does an attacker use to determine the location of a target wireless network?

Does the 802.11a wireless transmission standard operate in the 5-GHz range?

What is the mail unit of measurement for radio frequencies?

What type of antenna is being used in the figure above?

A(n) ____________________ is a device that sends out (radiates or transmits) and picks up (receives) radio waves.

Does the 802.11 standard focus on use of the physical and data-link layers (layers 1 and 2) of the OSI model?

____________________ software determines the location of a network, but it can also determine whether the network is an IBBS or ESS topology.

What are the lowest frequencies on which amateur radio operators can transmit?

What four general steps are used in the wireless communication authentication process?

The IBSS topology consists of ad hoc peer-to-peer communications between WNICs on individual computers.

At what speed must all devices that conform to the 802.11a standard be able to transmit?

In 802.11 communications, the shared secret is the SSID key used for encryption and decryption, and the key itself is encrypted.
