Question 32

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?

Options:

54 Mbps

65 Mbps

108 Mbps

144 Mbps

Question 33

One of your warehouse customers called you reporting problems with their WLAN in some locations that you designed and installed over a year ago. What should be one of your first considerations for your line of questioning?

Response:

Options:

DHCP lease exhaustion

Changes in receive gain

Inventory changes

Rogue APs from neighbors

Question 34

While configuring your site survey software for an upcoming manual survey project, you notice the configuration option for "Network Card

Simulation". What is the purpose of such a feature and when would you use it?

Options:

This setting allows the site survey software to convert the APs measured downlink RF data into a simulated data set as if the same data

were transmitted by a specific client station. It is useful for determining uplink client performance when clients are located far from APs as

well as projecting cell size for ad hoc networks.

Since WLAN adapters are not typically calibrated by manufacturers, this setting is a form of software calibration in which you can calibrate

an (uncalibrated) adapter to match one of the calibrated adapters shown in the list. This process improves the reliability of RF data collection

and reporting when uncalibrated adapters are used.

This is the configuration area in which you specify the adapter type that will be used for the site survey so that the survey software can

interpret that adapters reported metrics (based on proprietary formulas) into an RF measurement that is standardized by the survey software

and known to its users. This is done

Question 35

When designing a new WLAN infrastructure you also need to be aware of now the network is physically deployed and now the network is logically configured What are two documents that are helpful In this case?
