When designing a WLAN infrastructure implementation for high client density at a public venue such as a conference or stadium, what are common best practices? (Choose 2)

• A.UseWPA2-Personal security for ease of deployment
• B.Configure APs to transmit at or near their maximum power setting
• C.Use directional antennas to isolate the RF propagation
• D.Disable 802.11ac MCS rates to prevent high overhead protection mechanisms
• E.Implement a band steering feature for dual-band clients
• F.Use high-gain omnidirectional antennas to improve SNR

A WLAN transmitter that emits a 200 mW signal is connected to a cable with 3 dB loss.
If the cable is connected to an antenna with 10 dBi gain, what is the EIRP at the antenna element?

• A.10 dBm
• B.26 dBm
• C.30 dBm
• D.13 dBm
• E.20 dBm

What facts are true regarding controllers and APs in a Split MAC architecture? (Choose 2)

• A.Using centralized data forwarding, APs never tag Ethernet frames with VLAN identifiers or 802.1p CoS.
• B.Management and data frame types must be processed locally by the AP, while control frame types must be sent to the controller.
• C.With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.
• D.An IP tunnel is established between the AP and controller for AP management and control functions.
• E.In a distributed data forwarding model, the AP handles frame encryption and decryption.

What feature was introduced in the 802.11h amendment in order to uphold regulatory requirements for 5 GHz operations.

• A.Distributed Coordination Function (DCF)
• B.Transmit Power Control(TPC)
• C.256-QAM
• D.Radio Resource Management (RRM)

AP-1 is a 3x3:2 AP. STA-3 is a 3x3:3 client. What is the maximum number of spatial streams that can be used for a downlink HT-OFDM transmission from AP-1 to STA-3?

• A.Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.
• B.Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.
• C.Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.
• D.One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.
