Question 1

XYZ Company is using a single 802.11g access point in their New York branch office.
There are ten 802.11g wireless client stations currently on the network, each used by XYZ full-time employees. XYZ has hired a consultant to work on some accounting problems, and he is using an 802.11b radio card in his laptop. How might this affect XYZ wireless LAN throughput?

A. The network throughput capacity will be greatly decreased, and each 802.11g client station must begin using 20 us slot times. B. The network throughput capacity will remain unchanged, but the 802.11b client station will slow access down for the 802.11g stations. C. The network throughput capacity will greatly decreased due to mandatory use of DSSS- OFDM modulation. D. There will be no affect on the wireless LAN throughput capacity since the access point talks to each station at the highest rate at which the station is capable of transmitting. E. The network throughput capacity will decrease slightly since the only change will be that the 802.11b client station will transmit at 11 Mbps instead of 54 Mbps.

Question 2

When capturing traffic using a wireless LAN protocol analyzer that has a single 2.4 GHz radio card, which of the following is true?

A. The number of channels that an analyzer can capture simultaneously is dependent on the vendor implementation. B. All traffic on only one 2.4 GHz channel can be captured at any given time. C. All traffic on all 2.4 GHz channels can be captured simultaneously. D. All traffic on one 2.4 GHz channel and its directly adjacent channels can be captured simultaneously.

Question 3

Which three of the following are true regarding the duration/ID field in unfragmented Data frames?

A. If the More Fragments bit in the Frame Control field of the MAC header is set to 0, then the duration/ID field is also set to 0 B. The duration/ID field is always set to zero unless Data is sent to the broadcast address of FF:FF:FF:FF:FF:FF. C. The duration/ID field is measured in microseconds and always rounded up to the next highest integer. D. Valid frames with a duration/ID field value of ?32,767 are used by receiving stations to update their NAV. E. The duration/ID field is set to include the SIFS and ACK frame that follow the data frame. F. When a Data frame is sent to a multicast address, the duration/ID field is always set to
32,768.

Question 4

XYZ Corporation is renting space in a multi-tenant office building and has recently installed a new 802.11b wireless LAN in their office. The network administrator has very little experience with wireless LANs, and has recently purchased a wireless LAN protocol analyzer for diagnostic use. He has attended a wireless administration class and understands basic wireless LAN operation. During the course of troubleshooting a performance problem, the administrator cannot understand why he is seeing ATIM frames, CF-End frames, and PS-Poll frames on channel 2 all at the same time. You are hired by the administrator as a consultant to explain why this is happening. Which of the following explanations is NOT plausible?

A. Seeing ATIM frames, CF-End frames, and PS-Poll frames in the same capture is normal. Seeing these frames together means that Power Save Poll mode is in use on a PCF mode network. B. XYZ Corp's wireless LAN is using channel 2, and their neighbors in the building are running PCF mode networks and Ad Hoc networks on channel 2 as well. Each of the wireless networks have client stations operating in low-power mode. C. XYZ Corp's wireless LAN is using channels 1, 2, and 3. This design is causing adjacent channel interference, which is corrupting 802.11b frames. The analyzer is seeing this frame corruption and reporting the frames as it sees them. D. XYZ Corp's wireless LAN is using channels 1, 6, and 11. The frames the administrator is seeing while capturing on channel 2 are corrupted frame fragments that the analyzer is attempting to interpret.

Question 5

A process called preauthentication is specified by the 802.11 standard. Preauthentication is implemented by many vendors, and involves a client station performing what tasks?

A. Reassociating to the Extended Service Set through another access point just before it drops its connection with the existing access point. B. Authenticating to additional Basic Service Sets while maintaining an association to only one access point at a time. C. Authenticating with an Independent Basic Service Set and an Extended Service Set simultaneously. D. Reauthenticating with an Extended Service Set in approximately half of the time required by the association. E. Associating to multiple Basic Service Sets simultaneously.

Question 6

According to the IEEE 802.11 standard, what is one structural difference between a MAC Protocol Data Unit (MPDU) and a MAC Management Protocol Data Unit (MMPDU)?

A. The MPDU frame FCS field is 4 bytes, while the MMPDU frame FCS field is 8 bytes. B. An MMPDU header may only contain three address fields, but an MPDU may have four address fields. C. The MMPDU frame body is limited to 200 bytes, whereas the MPDU frame body can carry up to 2312 bytes. D. The MPDU header always places the BSSID in the first address field, but in the MMPDU the BSSID can be found in any of the address fields.
