Question 1

An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement

in throughput.

What is the most likely cause of this result?

AAPs are transmitting at a low transmit power

BThe clients were not upgraded

CAPs are mounted on the wall

DThe APs are still using the 5 GHz lower band

Answer : B

Question 2

In an RSN requiring low-latency reassociations and no fast secure roaming protocols, what security solutions are ideal for protecting VoWiFi communication?(Choose all that apply.)

Response:

AWPA2-Personal

BWPA-Personal

CWPA2-Enterprise

DWEP

E802.1X/EAP

Answer : A, C

WPA2-Personal and WPA2-Enterprise are ideal security solutions for protecting VoWiFi communication in an RSN requiring low-latency reassociations and no fast secure roaming protocols. WPA2-Personal uses a pre-shared key (PSK) to authenticate and encrypt the communication between the VoWiFi device and the access point. WPA2-Enterprise uses 802.1X/EAP to authenticate the VoWiFi device and the RADIUS server, and then derives a unique encryption key for each session. Both WPA2-Personal and WPA2-Enterprise use AES-CCMP as the encryption algorithm, which provides strong security and low overhead. WPA2-Personal and WPA2-Enterprise also support key caching and pre-authentication mechanisms, which reduce the latency and disruption during reassociations. These features are essential for maintaining the quality of service and user experience for VoWiFi communication.

WPA-Personal, WEP, and 802.1X/EAP are not ideal security solutions for protecting VoWiFi communication in an RSN requiring low-latency reassociations and no fast secure roaming protocols. WPA-Personal uses TKIP as the encryption algorithm, which is less secure and more computationally intensive than AES-CCMP. WPA-Personal also does not support key caching and pre-authentication mechanisms, which increase the latency and disruption during reassociations. WEP is an outdated and insecure encryption algorithm that can be easily cracked by attackers. WEP also does not support any authentication or key management mechanisms, which expose the VoWiFi communication to various attacks. 802.1X/EAP is an authentication framework, not a security solution. 802.1X/EAP alone does not provide any encryption or key management for the VoWiFi communication. 802.1X/EAP must be combined with a robust encryption algorithm, such as AES-CCMP, to provide adequate security for VoWiFi communication.

Question 3

You are selecting external antennas for use in a bridge link deployment. What chart should you request from the antenna vendors to make an

accurate selection?

AmW to dBm conversion chart

BdBm to dB conversion chart

CElevation chart

DAntenna coating chart

Answer : C

Question 4

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

AIn any stadium

BIn any office complex

CIn an airport

DIn any home office

Answer : C

Question 5

What is a radome?

AA type of semi-circular ceiling found in atriums and that is a heavy cause of RF reflection.

BA weatherproof piece of plastic covering an antenna or antenna system.

CThe unit used to measure the signal reflected backward by the end of a cable.

DA piece of metal positioned behind APs mounted on outdoor poles, designed to limit the butterfly effect.

Answer : B

Question 6

While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel

assignment algorithm of the WLAN infrastructure. What should you do to prevent this?

AReconfigure the automatic channel assignment settings to use only channels 1, 6, and 11

BPurchase and deploy new APs from a different vendor

CReconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

DLeave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

Answer : A

Question 7

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:

AConfirm the mounting hardware.

BChoose a different AP model.

CUpdate the documentation.

DConsult the RF designer.
