What is a typical characteristic of barcode scanners?

In what circumstance would you not enable DFS channels on a WLAN infrastructure?

Location technology (RTLS) can use which of the following methods?(Choose all that apply.)

Response:

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

In a manufacturing facility with highly reflective materials, you are planning an upgrade to your existing 802.11b WLAN implementation. You have

chosen a dual- band 802.11n infrastructure product for this purpose. Your client applications include:

✑ Handheld scanners for inventory management

✑ Toughbooks (laptops) mounted on forklifts for inventory and workflow management

✑ VoWiFi phones used by select employees throughout the facility

You are evaluating all of the 802.11n enhancements and determining which features to enable for your environment and applications.

In this scenario, what 802.11n enhancement typically should NOT be enabled on the 2.4 GHz radio of the new APs?

The installation crew for your WLAN project wants to install a few APs to locations nearby the ones specified in the RF design document. What next step should occur?

Response:

You told your customer that multipath fading may be mitigated simply by moving one or both of the receivers antennas a small amount, usually by

one to four wavelengths away from its original position. Your customer is prepared to make the change, but does not know the wavelength for

802.11ac.

What is the approximate wavelength of an 802.11ac radio wave?

Given: The 802.11ac APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the

802.11n and

802.11ac amendments. The AP is configured for a single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3x3

802.11n chip that supports two spatial streams.

What is the maximum MCS rate that could be supported by this AP?

Which one of the following is an essential metric to measure when performing a survey and design for VoIP across WLANs?

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?
