  A. 150
  B. 62
  C. 43
  D. 22

• Question 93:

  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?

  Response:

  A. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken
  B. Purchase and deploy new APs from a different vendor
  C. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and
  D. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result
  C. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and

• Question 94:

  During a post-validation assessment, you have configured a client for 802.1X/EAP but it is not passing authentication. Which areas should you check in the WLAN configuration? Response:

  A. Whether the RADIUS server is online and configured for the matching port on the APs and WLAN controllers
  B. Whether the RADIUS shared secret is properly configured on the supplicant and authentication server
  C. Whether the authenticator is configured to support the EAP type(s) your client is configured for
  D. Whether the client has a fully valid certificate
  A. Whether the RADIUS server is online and configured for the matching port on the APs and WLAN controllers

• Question 95:

  A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel's SSID and notices an AP in the hotel room.

  However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby.

  What would be the most likely cause of the low RSSI in the hotel room? Response:

  A. The AP in the room is transmitting on channel 13 and the traveler associated to a non- channel 13 AP located elsewhere.
  B. The AP in the room is using Bluetooth instead of Wi-Fi.
  C. The AP in the room is using ZigBee instead of Wi-Fi.
  D. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.
  A. The AP in the room is transmitting on channel 13 and the traveler associated to a non- channel 13 AP located elsewhere.

• Question 96:

  What is the purpose of Friis transmission equation [ (LdB) = 20 log(d) + 20 log (f) - 27.55 ]?

  A. Calculate earth bulge to determine minimum antenna height
  B. Calculate receive sensitivity for an 802.11 radio/antenna pair
  C. Calculate RF path loss in free space
  D. Calculate the loss experienced between the intentional radiator and antenna
  C. Calculate RF path loss in free space

• Question 97:

  A WLAN that you designed has been deployed in one area, users ate complaining that the network performs poorly. When you analyze the area you see that a new interferer has been introduced that was not there during the pre-design survey You've been informed that the interferer cannot be removed as it is an essential loT device. What action do you recommend?

  A. Reconfigure the channel plan to work around the interferer
  B. increase the output power of the APs covering that area by at least 25 percent to overpower the interferer
  C. Place a metal enclosure around the interferer
  D. Use 40 MHz channels so that the devices can use either 20 MHz block depending on where the interferer operates
  A. Reconfigure the channel plan to work around the interferer

• Question 98:

  When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to distributed? Response:

  A. Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.
  B. The router between the APs and the controller must be made aware of the APs as forwarding client STAs.
  C. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.
  D. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.
  C. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.

• Question 99:

  Four buildings are located in a square orientation to each other. Fisch Stix Food Company is requesting a PtMP link between the buildings. On the building with the root bridge link, what type of antenna is the best choice? Response:

  A. Vertically polarized omni
  B. 60?yagi
  C. Parabolic dish
  D. 100?sector
  E. Horizontally polarized omni
  D. 100?sector

• Question 100:

  You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for best performance.

  Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas you are monitoring and where VoWiFi service is desired?

  A. - 75 dBm
  B. - 72 dBm
  C. - 67 dBm
  D. - 62 dBm
  C. - 67 dBm
