CWNP Certified Wireless Analysis Professional 認定 CWAP-402 試験問題:
1. You are considering disabling the data rates of 1, 2, 5.5 and 11 in the 2.4 GHz band.
What advantage might this provide to the networks operating in this band?
A) Frames that must be transmitted at the lowest common data rate can be transmitted at higher data rates after the change
B) The range of the PHY preamble and header will be reduced
C) The RF signals will not travel as far
D) The antennas will be able to zero in on the higher data rates better
2. Several users have reported WLAN network connection issues and the users connect to the same AP. These users are spread throughout a 320 square meter area. Using a spectrum analyzer, you see RF energy across the entire 2.4 GHz band at significant signal strength levels. The users all connect using either HT or ERP devices.
What is the likely cause of this problem within this area?
A) Wide-band jammer
B) Microwave oven
C) Bluetooth devices
D) Video camera
3. When evaluating modulation and coding schemes, you must determine the best coding rate available. In 802.11 MCS tables, what is the best coding rate from the perspective of highest data rates?
A) 3/4
B) 2/3
C) 1/2
D) 5/6
4. What element was added to the general frame of 802.11 with the 802.11e amendment and the 802.11-2007 rollup?
A) HT Control
B) Address 4
C) RSN-IE
D) QoS Control
5. You have captured 802.11 traffic using an adapter that includes the radio tap header. You see several frames often called announcement frames in the capture.
What best describes these types of frames?
A) They are meant to provide information to the network that may result in state changes, but they are not open for rejection
B) They are used to allow a STA to awake from sleep and for no other reason
C) They only include beacon and probe request frames
D) They only include beacon and probe response frames
