Explanation

Question 6 of 23

1

Which statement defines the control frame operation between two stations?

Select one of the following:

A station sends an RTS frame as the first step in a three-way handshake that is required before sending data frames.
A station responds to an RTS frame with an ACK frame, thus providing permission for the requesting station to send a data frame.
If the sending station does not receive an ACK frame within a predetermined period of time, the sending station will drop the connection.
After receiving a data frame, the receiving station will send an ACK frame to the sending station if no errors are found.

Question 10 of 23

1

What is the purpose of the Distributed Coordination Function in an IEEE 802.11 WLAN environment?

Select one of the following:

It allows a client to detect whether or not a channel is clear prior to transmission.
It is used in a full-duplex environment to detect collisions.
It is used to send data over a half-duplex connection.
It allows the client to change transmission channels.

Explanation

Question 11 of 23

1

What is an advantage of SSID cloaking?

Select one of the following:

It provides free Internet access in public locations where knowing the SSID is of no concern.
Clients will have to manually identify the SSID to connect to the network.
SSIDs are very difficult to discover because APs do not broadcast them.
It is the best way to secure a wireless network.
