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.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.
• C.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.
• D.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.

The More Fragments subfield is found in which 802.11 frame field?

• A.Frame Control field
• B.MAC Service Data Unit field
• C.Protocol Order field
• D.Sequence Control field
• E.Fragmentation Control field

In the 802.11b analyzer trace shown, what explains why the Probe Request frame and Probe Response frame are transmitted at different data rates.

• A.802.11b client stations always send Probe Request frames at 1 Mbps regardless of configuration. The access point is required to send Probe Response frames at its highest basic rate, which in this case is 2 Mbps.
• B.The client station sends a Probe Request frame, which includes its supported rates list, using any one of its supported rates, which in this case is 1 Mbps. The access point sends a Probe Response frame, which includes its supported rates list and the basic rates list, using any supported rate common to both client stations, which in this case is 2 Mbps.
• C.An RF interference source is located near the client station sending the Probe Request frame causing it to slow its transmission rate in order to successfully communicate with the access point.
• D.The client station output power is set at approximately half of the access point output power. The higher output power of the access point allows it to successfully transmit frames at higher data rates than the client station.

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

Which of the following descriptions accurately describes IEEE 802.11 compliant Power Save mode operation in a DCF Basic Service Set?

• A.After waking from a low power state, client stations listen for the next beacon to determine if sending a PS-Poll frame to the access point is necessary.
• B.Upon receiving traffic for a dozing station, the access point wakes the client station using a PS-Poll frame so that the client station can receive the data.
• C.When the access point's buffer is full, the access point wakes all client stations using a PS-Poll frame so that they can receive the data.
• D.Following a period of time in a low power state, client stations wake themselves and automatically poll the access point for traffic using a PS-Poll frame.
• E.After waking at a schedule TBTT, client stations automatically send Null Function frames to the access point with the Power Management bit cleared.
