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)?

Choose the true statements regarding wireless network discovery processes for an HR-DSSS network.

In a Clause 18 (HR-DSSS) frame’s PLCP header, what does the 16-bit length field indicate?

XYZ Corporation is renting space in a multi-tenant office building and has recently installed a new ERP WLAN in their office. The network administrator has very little experience with WLANs, and has recently purchased a WLAN protocol analyzer for diagnostic use. He has attended a wireless administration class and understands basic WLAN operation. During the course of troubleshooting a performance problem, the administrator cannot understand why he is seeing ATIM frames, CF-End frames, and PS-Poll frames on channel 2 all at the same time. You are hired by the administrator as a consultant to explain why this is happening. Which explanations are plausible?

An IEEE 802.11 protocol analyzer using a single radio, dual-band 2.4 GHz (ERP) / 5 GHz (OFDM) PC Card is able to perform which tasks?

Given: An EDCA QoS BSS is operating as a Robust Security Network (RSN). Two QoS STAs in the QoS BSS are using a Direct Link to communicate.

When the RTS/CTS threshold is exceeded for a frame to be transmitted between the two QoS STAs, what is the frame exchange sequence, including interframe spaces?
