Question: 1

Your consulting firm has recently been hired to complete a site survey for a company desiring an indoor coverage WI-AN. Your engineers use predictive design software for the task, but the company insists on a pre-design site visit.

What task should be performed as part of the pre-design visit to prepare for a predictive design?

AInstall at least one AP on each side of the exterior walls to test for co-channel interference through these walls

BCollect information about the company's security requirements and the current configuration of their RADIUS and user database servers

CTest several antenna types connected to the intended APS for use in the eventual deployment

DEvaluate the building materials at the facility and confirm that the floor plan documents are consistent with the actual building

Question: 2

You support a WLAN using dual-band 802.11ac three stream access points. All access points have both the 2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 5 GHz and 20 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him?

AHis concern is valid and the company should upgrade all Ethernet links to 10 Gbps immediately.

BHis concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.

CHis concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.

DDue to 802.11 network operations and the dynamic rates used by devices on the network, the two radios will likely not exceed the 1 Gpbs Ethernet link.

Question: 3

What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?

AOFDM implements BPSK modulation to allow for data rates up to 7 Gbps.

BOFDM was first introduced in 802.11a and is used by the ERP, HT and VHT PHYs as well.

COFDM modulation is used only in 5 GHz 802.11 transmissions.

DOFDM was used by Frequency Hopping Spread Spectrum (FHSS) PHY devices.

AVerifying that a user is who he says he is.

BImplementing a WIPS as a full-time monitoring solution to enforce policies.

CGranting access to specific network services or resources according to a user profile.

DValidating client device credentials against a database.
