Question #7

The 802.11 series of standards calls for use of a Traffic Indication Map (TIM) and a Delivery Traffic Indication Message (DTIM). Which of the following is true regarding the TIM and DTIM in an infrastructure BSS?

A. A DTIM period of 0 means that every TIM is a DTIM.

B. The DTIM parameters are part of each Beacon's TIM Information Element, and they are used to indicate queued broadcast/multicast data to client stations using power management features in the BSS.

C. The first Beacon sent during a CFP must contain a DTIM

D. The DTIM is used in 802.11a and 802.11g Beacons whereas the TIM is used only in
802.11b Beacons. The DTIM purpose is to allow for higher rates of Beacon broadcasting and thus raise overall data rates in OFDM based systems.

E. The TIM and DTIM are both part of the Beacon management frame and are both sent in every Beacon for the purpose of announcing the modulation type and supported rate set of the access point.

F. The TIM is a field in the Beacon Management frame that holds a map of every client station associated to an access point. It is used for broadcast traffic delivery.

Question #8

Given the screenshot shown, choose the statement that accurately describes what is being seen by this protocol analyzer.

A. Bits (0-14) of the Duration/ID field in this frame indicates the AID of the source station

B. One wireless station sent an Echo Request (PING) to another wireless station through an access point.

C. The Duration field value's 164 microseconds is sufficient to reserve the RF medium for only the following frames: SIFS, ACK.

D. The BSSID has been randomly generated.

Question #9

ABC Company has hired you to troubleshoot an intermittent performance problem with their 802.11g wireless LAN. They have noticed that intermittently throughout a typical day, their wireless LAN latency increases enough to interrupt some mission critical applications.
ABC demands that you wait until after business hours to begin any troubleshooting that might cause service interruptions to the wireless network. Considering that ABC Company has no baseline analysis, what possible first step do you take toward troubleshooting ABC Company wireless network problem?

A. Using a protocol analyzer, you search for rogue access points that might be causing interference in the 2.4 GHz ISM band by emitting beacons.

B. After business hours, you enable the traffic generator function of a wireless protocol analyzer in order to simulate various high utilization conditions on the network while testing ABC Company applications.

C. You install protocol analyzer probes near each access point in order to see if a large percentage of data frames are carrying their maximum payload over the next two days.

D. You perform a walk-through of ABC Company premises during business hours using a protocol analyzer looking for data frames with high Retry counts and MAC CRC Error counts.

E. You perform a walk-through of ABC Company's premises during business hours using a protocol analyzer looking for 802.11g Basic Service Sets that have both 802.11b and
802.11g stations associated. You then compare this information to where the latency is being experienced.

F. After business hours, you search for wireless clients that are transmitting too many Probe Request frames and temporarily replace them as a troubleshooting measure.

Question #10

ABC Company's wireless LAN administrator is getting complaints from one user that his wireless LAN throughput is sluggish compared to other users in his area. The administrator takes his diagnostics laptop, which has a wireless protocol analyzer installed, to the area where the complaining user works. The administrator uses the PING utility to test connectivity from the complaining user's wireless client station to another wireless client station across the closest access point, while capturing the wireless frames. The administrator sees what is displayed in this screenshot. From this screenshot, which of the following statements can you conclude to be true that are related to the complaining user's throughput problem?

A. The access point is 802.11g, and the complaining user's wireless client station is
802.11b

B. The complaining user's wireless client station should be using RTS/CTS as a protection mechanism, but it is not.

C. The access point is not signaling for protection (Protection = no) in the Beacons, but it should be.

D. The complaining user's wireless LAN client utilities are configured for a small fragmentation threshold.

E. The complaining user's station is retransmitting fragments many times likely due to nearby RF interference

Question #11

How does an access point operating in DCF mode notify a client station operating in Power Save mode of multiple multicast frames queued at the access point?

A. The access point sets the Beacon DTIM to indicate that it has queued multicast traffic for the client station.

B. The access point responds to the client station PS-Poll frame with the AID subfield set to a value equal to the number of queued multicast frames.

C. The access point sets the Duration field of each Beacon to a value equal to the amount of time it will take to send all of the queued multicast frames to the client station.

D. The access point sends the client station a CF-Poll frame with the AID subfield set to the station MAC address.

E. The access point sets the More Data subfield in the Frame Control field of each Data frame to 1 until the last multicast frame is delivered.

C. Short PLCP Preamble support

D. Fast Sleep Recovery

E. Short Slot Time
