Question 1

Your customer's 802.11n laptops cannot detect the SSID in the 5 GHz band in a conference room, but your 802.11ac laptop connects without issue. What is the most likely explanation for this discrepancy?

Options :

A : The AP is configured to use channel 36

B : The customer laptop does not support OFDM

C : The AP is on channel 144

D : Their laptops are SISO clients

Answer: C

Question 2

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

Options :

A : After 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.

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

C : After 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.

D : Look 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 3

What type of site survey helps determine if roaming is functioning as intended?

Options :

A : Passive

B : Predictive

C : Active

D : Spectrum analysis walkthrough

Answer: C

Question 4

When performing a frame capture over the air during a voice call, you notice that frames in the downlink direction (from the AP to the client) are not being transmitted with the correct UP (User Priority) value for voice frames, but in the uplink direction (from the client to the AP), they are transmitted correctly. What is the likely cause of this issue?

Options :

A : Bad client driver

B : AP is not receiving enough PoE, thus not using QoS features

C : Somewhere on the wired network QoS markings aren't being trusted

D : Faulty antenna on the AP

Answer: C
