During an RFP analysis, one of the vendors mentioned that you’ll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?

A.

Because neither of the technologies support data rates over 1Gbps

B.

Because 802.11ax doesn’t support channel bonding

C.

Management overhead that is normal in WLANs will reduce the throughput of the client devices

D.

Because 802.11ac only supports one spatial stream

Your new customer is concerned about maintaining privacy for their proprietary information when you conduct information gathering for their WLAN design. Which document can you use to directly address their concern?

A.

NDA

B.

SoW

C.

BoM

D.

Hold Harmless

While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure. What should you do to prevent this?

A.

Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11

B.

Purchase and deploy new APs from a different vendor

C.

Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

D.

Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system’s requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system’s requirements?

A.

-70 dBm

B.

-67 dBm

C.

-65 dBm

D.

-63 dBm

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?

A.

Deploy all of the APs as they’re shown in the predictive design and perform an active site survey.

B.

Deploy all of the APs as they’re shown in the predictive design and perform a passive site survey.

C.

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

D.

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

An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement in throughput. What is the most likely cause of this result?

A.

APs are transmitting at a low transmit power

B.

The clients were not upgraded

C.

APs are mounted on the wall

D.

The APs are still using the 5 GHz lower band

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

A.

Set the transmit power for all APs

B.

Add pictures of the environment

C.

Nothing; just begin by adding APs, antenna and attenuators

D.

Calibrate the floor plan to increase accuracy

What document is typically created to launch a project?

A.

Bill of Materials

B.

Project Charter

C.

Work Breakdown Structure

D.
