• Question 82:

  Given:

  You were previously on-site at ABC's facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are on-site again to perform a network validation.

  When performing this type of post-deployment RF site survey for VoWiFi, what are two steps that must be performed? (Choose two)

  A. Coverage analysis to verify appropriate coverage and roaming boundaries
  B. Spectrum analysis to locate and identify RF interference sources
  C. Hidden node analysis to identify and relocate existing hidden nodes
  D. Protocol analysis to discover channel use on neighboring APs
  E. Application analysis with an active phone call on a VoWiFi handset

  E. Application analysis with an active phone call on a VoWiFi handset

• Question 83:

  Given: XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security. XYZ is interested in deploying standardized security features. In addition to WPA2Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.

  As XYZ Company selects a product to deploy, what two IEEE amendments should be supported to provide the management frame protection and fast secure roaming security features? (Choose two)

  A. 802.11j
  B. 802.11p
  C. 802.11r
  D. 802.11u

  C. 5/10 MHz
  D. 22 MHz
  E. 80 MHz
  F. 160 MHz
  A. 20 MHz
  B. 20/40 MHz

• Question 85:

  E. Sector
  A. Dipole
  B. Patch

• Question 86:

  Given:

  You have been sent as a consultant to a customer site that is experiencing problems with some 2.4 GHz clients on their 802.11a/g network. After collecting information from the company about the problem, your initial troubleshooting step is

  to find a client device experiencing performance problems and observe its 802.11 frame exchanges in a protocol analyzer. The retransmission rate for that client is 65% instead of the company's baseline, which is 9%.

  Based on this information, what troubleshooting step should follow to isolate the problem?

  A. Check the frame decodes in the protocol analyzer and look for an excessive number of deauthentication frames.
  B. Evaluate the client's operating frequency band with a spectrum analyzer, looking for a high noise floor or interference sources.
  C. Utilize a laptop-based site survey and planning tool to create a predictive model of the optimal AP placement in the customer's facility.
  D. With a protocol analyzer, identify the client's roaming threshold settings and reassociation behavior.
  E. Install Wi-Fi endpoint security and reporting software on the client device to monitor and log the retransmission behavior.
  B. Evaluate the client's operating frequency band with a spectrum analyzer, looking for a high noise floor or interference sources.

• Question 87:

  What facts are true regarding controllers and APs in a Split MAC architecture? (Choose 2)

  A. An IP tunnel is established between the AP and controller for AP management and control functions.
  B. Using centralized data forwarding, APs never tag Ethernet frames with VLAN identifiers or 802.1p CoS.
  C. With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.
  D. Management and data frame types must be processed locally by the AP, while control frame types must be sent to the controller.
  E. In a distributed (local bridging) data forwarding model, the AP handles frame encryption and decryption.
  A. An IP tunnel is established between the AP and controller for AP management and control functions.
  E. In a distributed (local bridging) data forwarding model, the AP handles frame encryption and decryption.
