1. Using the wireless LAN protocol analyzer's frame decode shown as a reference, which of the following access point data rate configuration settings must be correct?

A) Basic: 2, 1 Mbps - Supported: 11, 5.5 Mbps
B) Basic: None - Supported: 11, 5.5, 2, 1 Mbps
C) Basic: 11, 5.5 Mbps - Disabled: 2, 1 Mbps
D) Basic: 11, 5.5, 2 Mbps - Supported 1 Mbps
E) Basic: 11 Mbps - Supported: 5.5, 2, 1 Mbps

2. In order to get a visual representation of conversations happening across a wireless LAN, a Peer Map like the one shown can be used. Which of the following is true of most peer maps?

A) Peer maps can be used to quickly identify access points in a wireless LAN by using protocol filters.
B) Peer maps can show how much data is traversing a peer connection relative to other connections.
C) Peer maps can be used to identify modulation for each peer connection.
D) Peer maps can be used to display the security mechanisms used between each pair of network nodes.
E) Peer maps can be configured to display MAC layer or Network layer addressing.
F) Peer maps can be configured to show relative amounts of movement across a wireless LAN.

3. There are many differences between analyzing wireless and wired networks. In a wireless network, there is no guarantee one wireless client station can hear another station's transmissions. With no corrective actions or corrective mechanisms implemented, this hidden node situation may cause which measurable statistics parameter to be incremented in a wireless protocol analyzer?

A) Retransmission Count
B) Contention Window
C) Fragment Interval
D) DTIM Interval
E) Slot Time
F) Duration length

4. 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) 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.
B) After business hours, you search for wireless clients that are transmitting too many Probe Request frames and temporarily replace them as a troubleshooting measure.
C) 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.
D) 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.
E) 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.
F) 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.

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