Q22. 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 doesn’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.

Q23. A company wants to connect its headquarters to its remote office that is 13 kilometers away using a wireless bridge. What requirement must not be forgotten by their Wireless Engineer when considering the Fresnel Zone?

Earth bulge

Antenna gain

FSPL

Receive sensitivity

Q24. When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?

Frequency Selection

Roaming

AP vendor

Band steering

Q25. You have performed a validation site survey after deploying a WLAN infrastructure that is an All-Wireless- Office. One specific application of your customer is experiencing delay when using the application after moving from wired connectivity. After your validation, you realized that all APs are using 80 MHz channel- widths instead of 20 MHz on the 5 GHz band, as it was designed. What can be done to resolve the delay on this application?

APs should be using 160 MHz channel-widths to get more throughput

Reconfigure to use 20 MHz channel-widths, so reuse of the frequency is more effective

Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths

Add more APs using 80 MHz channel-widths

Q26. Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined?

All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

Q27. During a validation site survey, you realize that the installers mounted some of the APs above the ceiling.
They said that this was a request from the building architect due to aesthetics constraints. During the requirements gathering, you weren’t advised about any aesthetics constraints from the main stakeholder of the project. What should you do in this case?

Advise the stakeholder that WLAN performance requirements will not be met and a new design process will be needed to meet the requirements.

Leave it as it is and allow automatic channel management to correct any issues.

Increase the output power on all APs by 6 dB immediately.

Remove all external antennas and use only the internal antennas to reduce multipath.

Q28. What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?

Angle of Arrival (AoA)

Time of Arrival (ToA)

Time Difference of Arrival (TDoA)

Received Signal Strength Indicator (RSSI)

Q29. 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

Q30. During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent.
Every other time of the day, it works fine. What’s the likely cause of this issue?

Employees are using their cell data instead of using the Wi-Fi

The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch

Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 Ghz band

Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band

Q31. When designing a static channel plan for an office using voice devices near an airport, which range of channels should be avoided to ensure optimal performance when implemented?

36-40

44-48

116-124

1-11

Q32. What is the best method of gathering attenuation measurements from any building materials or objects?

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.

Q33. What service must be implemented on your customers’ network to authenticate users against an LDAP database prior to access to the WLAN infrastructure being granted?

NTP

RADIUS

SFTP

TLS

Q34. 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?

Missing AP licenses in the controller

Spanning-tree convergence

Layer 3 routing

Lack of PoE budget on the switch

Q35. What document should be created that provides instructions for install technicians to mount and configure APs?

Hold Harmless

Statement of Work

Bill of Materials

Physical installation guide

Q36. Which document provided to your customer should include all devices and parts that are going to be used during the deployment of their WLAN infrastructure?

SoW

BoM

Design report

Project plan

Q37. After designing a WLAN infrastructure using predictive design software. What’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 they’re shown in the predictive design and perform an active site survey.

Deploy all of the APs as they’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 AP’s placement.

Q38. What advantage provided by 802.11n and 802.11ac is not usable in 1X1:1 low-end client devices?

Channel bonding

MCS data rates

Maximal Ratio Combining

Mandatory data rates
