As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.
What application matches this description?

• A.Email
• B.FTP
• C.Video conferencing
• D.Skype chat
• E.Video-on-demand
• F.Voice

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users are highly transient (frequently come and go). With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client associations. The DHCP server is a Windows Server 2008 machine. Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?

• A.Set the inactive wireless client timeout (client age-out) to 5 minutes
• B.Set the RTS threshold to 2346 bytes
• C.Enable WLAN Controller DHCP relay
• D.Set the maximum client limit per radio to 64
• E.Set the DHCP lease for this pool to 20 minutes
• F.Set the 802.1X re-authentication timer to 10 minutes
• G.Set the AES rekey interval to 5 minutes
• H.Enable mandatory admission control

What is the DSCP Per Hop Behavior equivalent classification of the 802.11e AC_VO priority level?

• A.AF31
• B.CS3
• C.EF
• D.AF12
• E.VO

When deploying long-distance 802.11 bridge links (10 miles / 16 km), what parameter may be critical for improving data flow by reducing retries caused by the long distances?

• A.The Beacon interval
• B.The CTS-to-self threshold
• C.The sequence control field value
• D.The acknowledgement timeout threshold
• E.The minimum transmit data rate value
• F.The PHY parameter set field

A Layer 1 sweep was performed at a customer location, and you are asked to review a capture taken during the survey.

What is the meaning of the chart shown in the exhibit and how should it be interpreted?

• A.Real Time FFT means Real Time Fast Fourier Transform and shows the max value of the signal detected on each frequency in real time.
• B.Real Time FFT means Real Time Frequency Fundamental Texture and shows the value of the noise background generated by the card used to perform the Layer 1 sweep.
• C.Real Time FFT means Real Time Fast Frequency Timing and shows the RF pulses measured by the Layer 1 sweep tool.
• D.Real Time FFT means Real Time First Fundamental Trace and shows the value of the first signal detected on each frequency at each sweep interval.
