Which answer correctly completes the following sentence?
The WMM certification, created by the Wi-Fi Alliance, is based on the ___________ coordination function
with support for ___________ QoS priority.

What statement about the IEEE 802.11e QoS facility is true?

As a station moves away from the access point to which it is associated, it changes its data rate from 600
Mbps to 540 Mbps and then to 450 Mbps.
What IEEE 802.11 term is used to describe this functionality?

During the discovery and connectivity process, client and AP stations exchange information about their
supported data rates. After the association, how do client and AP stations select the supported data rate
that will be used to send an 802.11 data frame?

In an infrastructure Basic Service Set (BSS), how does the passive scanning process occur?

Prior to association, what parameter can 802.11 client devices measure and use to select the optimal
access point for association?

What term correctly completes the following sentence?
802.11a/b/g used a mandatory 800ns guard interval. 802.11n introduced an optional short 400ns guard
interval. Guard intervals (GI) are necessary in OFDM to reduce the likelihood of interference between two
consecutive ____________.

What term correctly completes the following sentence?
In an IEEE 802.11 frame, the IP packet is considered by the MAC layer to be a(n) _________.

As defined in the 802.11 specification, legacy Power Save requires an inefficient back-and-forth frame
exchange process. Due to this inefficiency, many WLAN device implementations use a variation of 802.11
Power Save to accomplish the same function.
What non-standard power save behavior is used by most Wi-Fi devices in actual legacy Power Save
implementations?

When compared with legacy Power Save mode, how does VHT TXOP power save improve battery life for
devices on a WLAN?
