Each of the following protocols is supported on an IEEE 802.11 network except
_____ is a group of wireless devices that is served by a single access point (AP).
Each WLAN must be assigned a unique identifier known as the _____.
With dynamic rate shifting implemented in a WLAN, what happens when a user moves farther away from the access point?
In order to accommodate additional wireless users over a wider area, which configuration should be used?
When a packet reaches the MAC layer (or the Data Link layer in the OSI model) these segments are formally known as frames. True or False?
The IEEE 802.11 standard specifies six categories of MAC frame formats. True or False?
At regular intervals the AP in an infrastructure network or wireless device in an ad hoc network sends a data frame to both announce its presence and to provide the necessary information for other devices to join the network. True or False?
In passive scanning, the wireless device must first send out a management probe request frame on each available channel and then wait for an answer from all available APs. True or False?
Because wireless LANs cannot limit access to the RF signal by walls or doors, wireless authentication requires the wireless device to be authenticated prior to being connected to the network. True or False?
_____ authentication requires the wireless device to correctly encrypt the challenge text.
Once a wireless device is authenticated the final step is to be accepted into the wireless network is a process known as _____.
The IEEE 802.11 standard specifies two procedures for transmitting on the WLAN, distributed coordination function (DCF) and an optional _____.
Instead of using Ethernet CSMA/CD, IEEE WLANs use _____.
Because IEEE 802.11 authentication is weak, another option is to use _____.
