CWNP Certified wireless analusis professional(cwap) 認定 PW0-205 試験問題:

1. What is an advantage of being able to fragment MSDUs and MMPDUs on a wireless network?

A) Increased throughput in an 802.11b/g mixed mode environment.
B) Decreased number of 802.11 control and management frames required for transmission.
C) Decreased translation time between 802.3 and 802.11 networks at the access point.
D) Increased throughput due to interference from other 802.11 stations.
E) Decreased retransmission overhead in a noisy RF environment.
F) Increased throughput in a clean RF environment

2. In which of the following IEEE 802.11a frames can the SSID be found providing the SSID is not specifically removed through firmware configuration by an administrator?

A) Authentication
B) Reassociation Request
C) Disassociation
D) Reassociation Response
E) Probe Response
F) Association Request

3. While analyzing a small office wireless network, you notice WEP is in use. In your protocol analyzer, where would you look to view the WEP Initialization Vector (IV) information?

A) In any Data frame Sequence Control field.
B) In any Data frame Frame Control field.
C) In any MPDU frame body.
D) In any PPDU header Service field.
E) It is not possible to view the IV information because it is encrypted.

4. Which of the following is true regarding frame acknowledgement in an 802.11 wireless LAN?

A) Frame fragments are acknowledged individually (with an ACK frame)
B) A client station reassociation request frames are only acknowledged with a reassociation response from the access point when roaming in a wireless LAN secured with 802.1X/EAP.
C) ACK frames following Data fragments set the NAV of competing stations for a duration equal to two SIFS plus the next Data fragment and its ACK.
D) In PCF mode, WEP-Data frames are only acknowledged by client stations, never by access points.
E) Beacon frames are acknowledged by all client stations configured for PCF mode.
F) Probe request acknowledgement (sending of a probe response) is configurable in the access point and is always linked to SSID broadcast configuration in Beacons.

5. In the graphic, there are three active 802.11b access points. These access points are on channels 1, 6, and 11. In the graph to the left, signals on channels 1, 6, and 11 are shown in green bars above their channel number. What do the brown bars on channels 2, 3, 5, 7,
10, and 12 represent?

A) Transmissions on adjacent channels by DSSS access points that are not part of this wireless LAN system
B) Channel harmonics (resonant frequencies)
C) Unassociated stations sending probe request frames trying to locate an access point with which to associate
D) Transmission echoes (multipath)
E) Cross channel interference
F) Stations associated to the channel 1, 6, & 11 access points
