質問 1：
Shown is a screenshot of a wireless protocol analyzer displaying the decode information for a single 802.11 encrypted data + CF-Poll frame. The network on which this information was captured was operating in DCF mode using WEP, and this particular frame was sent from a client station (STA) to an access point (AP). As a protocol analyst, how would you explain the existence of this frame on the wireless medium given the information in the decode?

A. The frame was sent by a client station that does not comply with IEEE 802.11b standard to an access point that is certified.
B. The frame was misinterpreted based on insufficient information received by the analyzer due to frame corruption.
C. The access point is operating as a repeater, and clients must poll repeater access points in order to transmit data frames through them.
D. The 802.11 network is using both version 1 and version 2 protocols simultaneously.
This unexpected frame is from the version 2 protocol set.
正解：B

質問 2：
Before accurate statistical troubleshooting with a wireless protocol analyzer can be performed on a wireless LAN, which of the following must be completed?
A. Traffic injection analysis
B. Directional traffic filtering
C. Quality of Service (QoS) design
D. Baseline traffic analysis
E. Operational traffic policy
正解：D

質問 3：
Which of the following frame types can be used by an access point to set the NAV value on all associated stations to zero when sent to a broadcast address?
A. CF-End + CF-ACK
B. CF-Poll
C. Null Function
D. Data + CF-ACK
E. RTS
正解：A

質問 4：
When RTS/CTS is used in DCF mode, what is the frame exchange sequence between two wireless stations including interframe spaces?
A. EIFS-RTS-CTS-SIFS-DATA-SIFS-ACK
B. DIFS-RTS-ACK-CTS-ACK-DATA-SIFS-ACK
C. DIFS-RTS-CTS-SIFS-ACK-DATA-SIFS-ACK
D. PIFS-RTS-SIFS-CTS-SIFS-DATA-SIFS-ACK
E. DIFS-RTS-SIFS-CTS-SIFS-DATA-SIFS-ACK
正解：E

質問 5：
Determine which of the following statements is true using the information in the analyzer trace shown.

A. This analyzer trace displays two PING Request / PING Reply packet exchanges between two wireless client stations through an access point.
B. This analyzer trace displays one PING Request / PING Reply packet exchange between two wireless client stations through an access point
C. This analyzer trace displays one PING Request / PING Reply packet exchange between a wireless client station and a wired station through an access point.
D. This analyzer trace displays two PING Request / PING Reply packet exchanges between two wireless client stations that are part of an IBSS.
正解：B

質問 6：
Referencing this decode of an 802.11b frame, choose the statement that could be true.

A. This frame was sent to a wireless client station from a node on the wired segment and WEP was not used.
B. This frame was sent from one access point to another access point along a wireless distribution system.
C. This frame was sent from a wireless client station to an access point for the purpose of managing the access point's configuration.
D. This frame was the first fragment in a series of 3 fragments (as part of a fragment burst) sent from a wireless client station to a station on the wired network.
E. This frame was sent from a wireless client station to request information about BSSs within range.
正解：E

質問 7：
In an 802.11 wireless LAN frame with either long or short preambles, the PLCP Header consists of multiple fields. Which of the following are valid PLCP Header fields?
A. MSDU
B. Sync
C. SFD
D. FCS
E. Signal
正解：D,E

質問 8：
Given the 802.11 frame decode shown, which of the following statements are true.

A. The frame is a layer 2 broadcast.
B. The 44 ec duration value is sufficient to cover the SIFS and ACK to follow
C. The MSDU was successfully encrypted with WEP
D. The frame is the last fragment in a sequence of 3 fragments.
E. The frame in the decode is an MMPDU.
正解：B,C
