What statement identifies the purpose of an RP site survey seport?
Answer(s): D
Which of the following may result from using RTS/CTS in a wireless LAN?
According to the study guide, in a situation where a hidden node problem has occurred in the wireless network, RTS/CTS may be used to eliminate the overhead of the continous collision of packets that is severely decreasing the overall throughput of the Wireless LAN. RTS/CTS is not associated with frame fragmentation. Therefore, the answer should be D.
What is a method of client authentication onto a wireless LAN?
Answer(s): B
The open system authentication is the default method of authentication between your card and the access point. Anybody that wants to be authenticated with the base station can be. Even when this information is sent using the wired equivalent privacy protocol (WEP), which is designed to provide for confidentiality when using a wireless network, the authentication management frames are still sent in clear text, thus helping to defeat the use of this particular security protocol.
What option describes a device that supports VPN connectivity and authentication for wireless access users?
Answer(s): A
Authentication technologies incorporated into enterprise wireless gateways are often built into the more advanced levels of access points. For example, VPN and 802.1x/EAP connectivity are supported in many brands of enterprise level access points.

According to the IEEE 802.11 standard, what is the largest frame size that can traverse a wireless LAN without mandatory fragmentation?
Answer(s): C
Data frame is variable in length (29-2346 bytes). Duration ID field contains a value, measured in microseconds from the end of the frame, sufficient to protect the transmission of a subsequent acknowledgement frame. If the data frame is multicast address, the duration/ID value is zero.
