You need to determine RF activity over time in a spectrum analyzer. It is to be able to see the activity and the amplitude of that activity.
What kind of view should be used?

• A.Device listing
• B.Swept spectrogram
• C.Channel listing
• D.Real-time FFT

When evaluating modulation and coding schemes, you must determine the best coding rate available. In
802.11 MCS tables, what is the best coding rate from the perspective of highest data rates?

• A.5/6
• B.2/3
• C.1/2
• D.3/4

Why would a STA that supports 802.11k Radio Measurement send a Neighbor Request to an AP?

• A.To learn about neighboring interference sources and tune its RF radio accordingly
• B.To inform the current AP about the STA's intent to roam to a neighboring AP, ensuring a seamless handover
• C.To request a list of neighboring APs which the STA can use as roaming candidates
• D.To request a list of neighboring STAs which enables the STA to better pick the right protection mechanisms

What is an AIFS?

• A.The shortest period of time a STA can sleep
• B.A medium access method introduced by 802.lln, but never implemented
• C.A form of aggregation performed at the PHY layer based on 802.lie UP values interpreted from DSCP values
• D.A variable Interframe Space introduced by 802.lie to help prioritize medium access for different Access Categories

While troubleshooting DHCP issues, you perform a protocol capture in order to determine if the DNCP pool is depleted. The capture does not show DHCPnak messages.
Where else could you look to determine if the pool is depleted?

• A.Spectrum analyzer
• B.Switch logs
• C.DHCP server logs
• D.AP logs
