Which statements are true regarding an IEEE 802.11 frame’s PLCP preamble?

ERP access points may provide which service to increase overall network performance in a BSS when only ERP stations are associated to the access point?

WMM-PS trigger frames can be what type of IEEE 802.11 frames?

ABC Company has two access points (AP-1 and AP-2) connected to an Ethernet hub. Which statements describe how each access point will handle a frame sent from a wired node to a wireless station associated to AP-1?

Given: ABC Company is interested in deploying an IEEE 802.11 network that supports wVoIP devices. During a proof-of-concept test, they deployed a WLAN controller, one lightweight AP, and QoS features in support of their voice and data client devices in the 2.4 GHz band. The network administrator has configured the access point to perform client connectivity and rogue wireless device scanning. As a test, John places a rogue AP on his network and configures it to use channel 11. The WLAN controller never reports the rogue AP.

Why does the WLAN controller never report the rogue AP?

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

Given: ABC Company has recently installed its first access point. The access point is an ERP unit, and both ERP and HR-DSSS client stations will be used on the wireless network simultaneously. The network administrator has appropriately configured the access point and all of the company’s HR-DSSS wireless client stations to use short preambles for CCK transmissions. A visitor begins using a Personal Data Assistant (PDA) with an integrated HR-DSSS radio configured for use of long preambles on ABC’s wireless network.

Which statement describes what the network administrator will see with a wireless protocol analyzer?

Which statements must be true before an IEEE 802.11 station may transmit a Data frame on the RF medium using DCF?

What frame subtypes are specified in the IEEE 802.11 standard (as amended)?
