Question 1

You are preparing to perform a site survey for a company that processes meat, but some areas are restricted due to high security. What should you do in order to proceed with the site survey?

AGain appropriate access and clearance to perform the site survey

BGain meat processing access certification from the FDA

CEnsure that you and your team are using food industry approved USB adapters for the survey

DJust begin the survey, they will understand

Answer : A

Question 2

A controller-based WLAN infrastructure has its controller on a different subnet than its access points (APs). What device must be used to enable communication between the controller and the APs?

ANTP server

BRouter

CPoE Layer 2 switch

DWireless bridge

Answer : B

Question 3

What is the best method of gathering attenuation measurements from wall materials?

AAfter measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall on one side and your measuring device 1 meter (3.2 feet) away from the wall minus the width of the wall. Take measurements and compare the difference.

BUse the pre-built attenuation values in the predictive design tools as they are more accurate than free-space metrics gathered with commercial devices.

CAfter measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall on one side and your measuring device 0.67 meters (2 feet) away from the wall on the other side. Take measurements and compare the difference.

DLook on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material providers' websites.

Answer : C

Question 4

When designing for OFDMA, why might the same channel bandwidth result in greater efficiency than that available in 802.11n and 802.11ac?

AThe design will use MU-MIMO, which is not available in either 802.11n or 802.11ac.

BThe design will use transmit beamforming, which is not available in either 802.11n or 802.11ac.

CThe design will use RUs that allow for transmissions to multiple client devices concurrently without the use of MU-MIMO.

DThe clients will use UL MU-MIMO coupled with DSSS, which was not available in 802.11n or 802.11ac.

Answer : C

Question 5

APatch

BDish

CGrid

DLow-gain dipole
