Chapter 20 Quiz (ITN107) - Wireless Networking

What centrally connects wireless network nodes in the same way that a hub connects wired Ethernet PCs?

WAP (Wireless Access Point) (shut up!)

What type of wireless network is very small and designed for "quick-and-dirty" jobs?

PAN (Personal Area Network)

What WAP settings should be adjusted in an environment with overlapping Wi-Fi signals?

Channel and frequency

Where is the best location for an omni-directional antenna in your home or office?

Near the center

What method enables you to limit access to your wireless network based on the physical, pre-defined address of the units' wireless NIC?

MAC address filtering

What 802.11n feature increases its range and speed?

Which standard has a security flaw that allows a hacker to guess an eight-digit code?

WPS (Wi-Fi Protected Setup)

What is the standard straight-wire omnidirectional wireless antenna called?

Dipole

What method do wireless networks use to determine if other nodes are currently broadcasting?

Which standard or protocol provides a security improvement that WPA addresses over WEP?

EAP (Extensible Authentication Protocol)

Which standard or protocol represents a security improvement in WPA2 over WEP and WPA?
