Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?

A.

Cat-5

B.

Cat-6

C.

Cat-5e

D.

Cat-6a

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?

A.

SoW

B.

BoM

C.

Design report

D.

Project plan

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

A.

Personal Protective Equipment (PPE)

B.

Low gain antennas

C.

Low power APs

D.

Indoor APs

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?

A.

11 dBm

B.

6.25 mW

C.

125 mW

D.

17 dBm

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?

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

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

A.

Channel bonding

B.

MCS data rates

C.

Maximal Ratio Combining

D.

Mandatory data rates

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?

A.

36-40

B.

44-48

C.

116-124

D.

1-11

In addition to a copy of your design, which tools should you use to ensure the installation team deploys APs where you have them designed to be located?

A.

GPS and a map

B.

RF spectrum analyzer and packet capturing software

C.

Ladder and a pen

D.

Camera and marking tools

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?

A.

To explain design decisions and ensure understanding of design documents.

B.

To discuss AP functionality.

C.

To explain how Wi-Fi works.

D.

To justify the budget.

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

A.

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.

B.

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

C.

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.

D.

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.
