Question # 6

After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you ' ve

designed the

WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn ' t follow your guidelines when configuring the WLAN

infrastructure. What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?

Add more APs to the infrastructure

Increase the transmit power on all APs

Turn-off 2.4 GHz radios on some APs

Use all channels available in the 2.4 GHz band

Question # 7

Excessive uplink RTP frame retransmissions can result in ____________.

Deauthentication of the transmitter by the receiver

Lowering of the data transmission rate by the transmitting station

MOS scores in excess of 5

Head-of-Line blocking at the receiver

Question # 8

What strategy can be used to ensure efficient cell overlap for VoIP site surveys?

Response:

Measure the percentage of cell overlap using the cell overlap feature in the site survey software.

Increase the output power of the radio in all APs.

Install higher gain antennas in the APs.

Ensure at least two APs can be seen with appropriate signal strengths from each location.

Question # 9

During a customer walkthrough you notice an area of the CAD drawing where it is not accurate. What next step should you take?

Response:

Redraw the portions of the map that have changed.

Do not survey that area.

Request a new version.

Request the survey team to do their best to walk where necessary and use the references on the map.

Question # 10
