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.

As an implementation engineer, you have just received initial design specs from a network designer for your dual-band 802.11n deployment. The network design documents prescribe the following data rate configuration for the 2.4 GHz radio:
Basic Rates - 5.5, 6, 11, 12 Mbps
Supported Rates -9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15
What will result from this design strategy?

• A.Protection mechanisms will always be in use on this network to support 5.5 and 11 Mbps as basic rates.
• B.HR/DSSS (802.11b) stations will not be able to associate to the service set.
• C.MCS 0 will represent the lowest data rate that can be used in the service set.
• D.By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force 802.11b clients to use these higher data rates.
• E.This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory data rates for 802.11g/n.

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

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

What is the purpose of DHCP Option 43, and how is it used with WLANs?

• A.It provides clients with a temporary IP address on a restricted VLAN until 802.1X authentication is completed. Then the client receives its long-term IP address.
• B.It integrates a DHCP server with AAA servers and user databases to dynamically assign IP addresses to client devices. During 802.1X, the AAA server uses Option 43 to notify the DHCP server what IP pool the client's address should be drawn from.
• C.It provides IP address bindings for specific network nodes that require long-term IP address assignments. WLAN controllers are configured to use Option 43 to receive long-term IP address leases that are centrally managed with DHCP.
• D.It supports vendor-specific IP address attributes for node discovery purposes. APs use Option 43 with vendor class identifiers to obtain the IP address of a centralized WLAN controller.

Excessive uplink RTP frame retransmissions can result in ____________. (Choose 3)

• A.Increased jitter in a VoWiFi connection
• B.Lowering of the data transmission rate by the transmitting station
• C.Head-of-Line blocking at the receiver
• D.MOS scores in excess of 5
• E.Deauthentication of the transmitter by the receiver
• F.Shortened battery life of a transmitting station
