What factors will have the most significant impact on the amount of wireless bandwidth available to each station within a BSS? (Choose 2)

A. The number of clientstations associated to the BSS

B. The power management settings in theaccess point's beacons

C. The presence of co-located (10m away) access points on non-overlapping channels

D. The data rates at which nearby client stations are transmitting and receiving data

E. The layer 3 protocol used by each station to transmit data over the wireless link

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. 13 dBm

C. 20 dBm

D. 26 dBm

E. 30 dBm

What statements about the beamwidth of an RF antenna are true? (Choose 2)

A. Thelower the gain of an antenna, the moreap-1 is narrow one or both beamwidths become.

B. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

C. Horizontal and vertical beamwidth are calculated at thepoints in which the main lobe decreases power by 3 dB.

D. Horizontal beamwidth is displayed (in degrees) on the antenna's Azimuth Chart.

You have been sent as a consultant to a customer site that is experiencing problems with some 2.4 GHz clients on their 802.11a/g/n/ac network. After collecting informationfrom the company about the problem, your initial troubleshooting step is to find a client device experiencing performance problems and observe its 802.11 frame exchanges in a protocol analyzer. The retransmission rate for that client is 65% instead of thecompany's baseline, which is 9%.

Based on this information, what troubleshooting step should follow to isolate the problem?

A. Check theframe decodes in the protocol analyzer and look for an excessive number of deauthentication frames.

B. Evaluate the client's operating frequency band with a spectrum analyzer, looking for a high noise floor or interference sources.

C. Utilize a laptop-based site survey and planning tool to create a predictive model of the optimal AP placement in the customer's facility.

D. With a protocol analyzer, identify the client's roaming threshold settings and reassociation behavior.

E. Install Wi-Fi endpoint security and reporting software on the client device to monitor and log the retransmission behavior.

The 802.11 protocol specifies a fundamentalchannel access method that is required for all stations and is available for use in all IBSS and BSS networks.

What is this fundamental channel access method called?

A. DCF

B. PCF

C. HCF

D. EDCAF
