Question # 4

After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, youâ€™ve designed the WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didnâ€™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 # 5

When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesnâ€™t have enough USB ports, you use a 4-port powered USB 3.0 hub. What issues could be caused by the use of USB 3.0 that will impact your site survey?

It does not give you enough bandwidth to collect data coming from all of the adapters.

It does not give you enough power for all four of your adapters.

It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.

It generates noise in the 5 GHz band, giving you a false perception of the noise floor.

Question # 8

After designing a WLAN infrastructure using predictive design software. Whatâ€™s the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?

Deploy all of the APs as theyâ€™re shown in the predictive design and perform an active site survey.

Deploy all of the APs as theyâ€™re shown in the predictive design and perform a passive site survey.

Use a client device positioned where the APs will be installed and measure the signal from the client device.

Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each APâ€™s placement.
