Certified Wireless Design Professional (CWDP-303) Practice Test

Questions # 11:

A controller-based WLAN infrastructure has its controller on a different subnet than its APs. What device must be used to enable any communication between the Controller and the APs?

Options:

NTP server

Router

PoE Layer 2 switch

Wireless bridge

Questions # 12:

You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason for this result?

Options:

USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.

The transmit power on the APs is higher than needed.

Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters.

USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters.

Questions # 13:

Which DHCP option, when required, should be configured and enabled to help APs locate their wireless LAN controller?

Options:

150

Questions # 14:

When deploying a new WLAN infrastructure using PoE to power the APs, you realize that a known good AP is not powering up. You use the same cable to connect your laptop and connect without any trouble. What is the most likely reason the AP did not power up?

Options:

Missing AP licenses in the controller

Spanning-tree convergence

Layer 3 routing

Lack of PoE budget on the switch

Questions # 15:

During your first pre-deployment meeting with the deployment team, you hand out the full design documentation to all of them. What’s your primary goal during this meeting?

Options:

To explain design decisions and ensure understanding of design documents.

To discuss AP functionality.

To explain how Wi-Fi works.

To justify the budget.

Questions # 16:

You are conducting a physical site survey where heavy machinery is repaired. What is a common item required specifically for this type of survey?

Options:

Personal Protective Equipment (PPE)

Low gain antennas

Low power APs

Indoor APs

Questions # 17:

After importing a floor plan to a predictive design tool, what should be done prior to adding APs, antennas and attenuators (e.g., walls)?

Options:

Set the transmit power for all APs

Add pictures of the environment

Nothing; just begin by adding APs, antenna and attenuators

Calibrate the floor plan to increase accuracy

Questions # 18:

What is the best method of gathering attenuation measurements from any building materials or objects?

Options:

After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the difference.

Use the pre-built attenuation values in the predictive design tool.

After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall or object on the other side. Take measurements and compare the difference.

Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material provider’s websites.
