Questions # 61:

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?

Options:

A.

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

B.

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

C.

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

D.

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

Questions # 62:

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

Response:

Options:

A.

Redraw the portions of the map that have changed.

B.

Do not survey that area.

C.

Request a new version.

D.

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

Questions # 63:

Name the audience type not addressed in this chapter for HLDs.

Response:

Options:

A.

Operations

B.

Questions # 64:

A museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you

do to meet this requirement?

Options:

A.

Lock the AP inside of a metal box

B.

Place the APs in between walls and I-beams

C.

Use an 802.11b AP, so it looks old enough to be in a museum

D.

Use a plastic cover that could blend in with the environment

Questions # 65:

If the amplifier in Question 4 has a noise figure of 10 dB but a gain of 0 dB, what is the total noise figure of the cable, amplifier, and filter in series?

Response:

Options:

A.

75 dB

B.

16 dB

C.

10 dB

D.

70 dB

Questions # 66:

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?

Options:

A.

Add more APs to the infrastructure

B.

Increase the transmit power on all APs

C.

Turn-off 2.4 GHz radios on some APs

D.

Use all channels available in the 2.4 GHz band

Questions # 67:

What advantages are provided by per-user PSKs when compared with ESS-wide PSKs?(Choose all that apply.)

Response:

Options:

A.

Per-user PSKs allow easier user-based access control with WPA/WPA2-Personal security.

B.

Per-user PSKs are easier to manage if a PSK is compromised or an employee leaves a company.

C.

Per-user PSKs are standardized and certified by the Wi-Fi Alliance.

D.

Per-user PSKs are more secure than ESS-wide PSKs because they support mutual authentication.

Questions # 68:

You are selecting external antennas for use in a bridge link deployment. What chart should you request from the antenna vendors to make an

accurate selection?

Options:

A.

mW to dBm conversion chart

B.

dBm to dB conversion chart

C.

Elevation chart

D.

Antenna coating chart

Questions # 69:

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?

Options:

A.

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

B.

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

C.

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

D.

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

Questions # 70:

A high power radio system transmits at 40,000 Watts. What is this power in dBm? Solve this without a calculator.

Response:

Options:

A.

46 dBm

B.

76 dBm

C.

56 dBm

D.

66 dBm
