XYZ Corporation has an 802.11b/g mixed mode deployment, and they are currently experiencing random throughput problems around the entire network. When the network was originally installed, there were both 802.11b and 802.11g stations on the network, but throughput levels were acceptable at any given time. To troubleshoot this issue, you have deployed a distributed wireless protocol analyzer, and it has noted a significantly greater percentage of 1 Mbps Data traffic being sent in random places across the network as compared with the initial baseline testing. When the network was installed, you considered only a minimal amount of 1 Mbps Data traffic acceptable. What could be causing this problem, and how would the analyzer know about the 1 Mbps traffic?

• A.A new 802.11g station has a minimum transmission rate set at 1 Mbps. The analyzer views the Start Frame Delimiter (SFD) field in the PLCP header to see the frames?transmission rates.
• B.Due to changes in the office environment, some client stations are moving further away from the access points than when the baseline tests were performed. The analyzer views the SIGNAL field in the PLCP header to see the frames transmission rates.
• C.An access point configured for 802.11b/g mixed mode has been reconfigured to send downstream traffic in a round-robin fashion when protection is enabled. The analyzer views the length of the preamble to determine the transmission rate of associated stations.
• D.A wireless network management system has updated all access points to allow only use of the long slot time. The analyzer views the SERVICE field in the PLCP header to see the frames?transmission rates.

Wireless LAN protocol analyzers often have a set of features for recording statistics and reporting information trends. What tasks do organizations most often use these features to perform?

• A.Analyzing the number and type of wireless LAN attacks over a period of time
• B.Troubleshooting conversations between wireless nodes and other nodes (both wired and wireless) on the network.
• C.Measuring the baseline throughput across particular access points in the wireless LAN network after installation.
• D.Identifying rogue access points and stations on the wireless network and generating alarms that can be read by a centralized console.
• E.Analyzing the average throughput of a single user across an ESS over a period of time.

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 be used to identify modulation for each peer connection.
• C.Peer maps can be configured to display MAC layer or Network layer addressing.
• 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 show relative amounts of movement across a wireless LAN.
• F.Peer maps can show how much data is traversing a peer connection relative to other connections.

The 802.11 standard allows for frame fragmentation due to an unreliable medium. Which two fields in the 802.11 frame are involved in numbering data frame fragments and notifying the receiving station when all of the fragments of a data frame have been received?

• A.Ordered Service field
• B.Capability Information field
• C.Sequence Control field
• D.Frame Control field
• E.ERP Information field
• F.DS Parameter field

Which statement accurately describes why the Traffic Indication Map (TIM) information element is not shown in this Beacon Management frame?

• A.This Beacon frame is using a DTIM instead of a TIM.
• B.Beacons only contain TIMs when the Power Management bit in the Frame Control field of the MAC header is set to 1
• C.This model of access point does not support 802.11 compliant Power Save mode.
• D.This Beacon was captured on channel 2 but was transmitted on channel 1. This caused a loss of information elements within the Beacon.
• E.Beacons transmitted by 802.11 IBSS networks do not include TIMs.
