When an access point sends an RTS frame, the duration field will contain an amount of time, measured in microseconds, equal to which of the following?

The IEEE 802.11 (as amended) Dynamic Frequency Selection (DFS) service is capable of performing what functions?

In an ERP QoS BSS using APSD, when is the Power Management subfield of the Frame Control field set to a value of 1?

Which statement is FALSE regarding use of admission control in a QoS BSS?

Which statements accurately describe IEEE 802.11 EDCA collision handling in a WMM compliant infrastructure WLAN?

What is indicated to a QoS AP when a QoS STA sets U-APSD Flag bits to 1 in Association and Reassociation frames?

What does a TXOP Limit value of 0 in the EDCA Parameter Set included in a QoS AP’s Beacons or Probe Response frames indicate?

Given: ABC Company is implementing a QoS enabled infrastructure that will support both voice and data. The WLAN controller is connected to one of three core layer-3 Ethernet switches. Each core layer-3 Ethernet switch has multiple edge layer-2 Ethernet switches attached. Lightweight APs are connected to all edge layer-2 Ethernet switches. The WLAN controller is on subnet 10.1.1.0/24, and the APs are on numerous other subnets. The APs are connected to the WLAN controller via LWAPP tunnels.

When IEEE 802.11 frames arrive at a lightweight AP from a QoS STA that need to be sent to the WLAN controller, which bits can the AP mark to signal the layer-2 and layer-3 Ethernet switches to use higher priority processing?

Many autonomous access points support IEEE 802.1Q VLAN tagging. When analyzing a WLAN system using IEEE 802.1Q tags, where can the VLAN tag number be seen?

What events will cause an established TSPEC to be deleted by a AP?
