• Question 4:

  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 WPA2-Enterprise 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, which are included in 802.112012, should be supported to provide the management frame protection and fast secure roaming security features?

  A. 802.11j and 802.11k

  B. 802.11z and 802.11w

  C. 802.11r and 802.11w

  D. 802.11r and 802.11k

  Correct Answer: C

  You are selecting antennas for a WLAN operating in the 5 GHz frequency band. What specifications should be evaluated for an antenna before it is implemented in this WLAN system?

  A. 802.11ad compatibility

  B. TPC support

  C. Impedance in Ohms

  D. Return Loss Rating

  Correct Answer: C

• Question 6:

  You are selecting antennas for a WLAN operating in the 5 GHz frequency band. What specifications should be evaluated for an antenna before it is implemented in this WLAN system? (Choose 3)

  A. 802.11ad compatibility

  B. TPCsupport

  Correct Answer: CDF

• Question 7:

  What word describes the bending of an RF signal as it passes through a medium of a varying densityfrom that of free space?

  A. Diffraction

  B. Reflection

  C. Refraction

  D. Diffusion

  E. Scattering

  Correct Answer: C

• Question 8:

  ABC Company has thousands of Wi-Fi users accessing their network on a daily basis. Their WLAN consists of 700 access points, 6 WLAN controllers, and a wireless network management system.

  Whatnetwork functions are performed by the enterprise-class WNMS?

  A. Radio management, fast roaming, key caching, and other centralized control plane operations

  B. Centralized bridging of guest data traffic and application of firewall and QoS policies to data

  C. Management of WLAN controller configuration and provisioning of firmware updates

  D. Generating, encrypting, and decrypting 802.11 frames and collecting RF radio data.

  Correct Answer: C

• Question 9:

  In an infrastructure Basic Service Set (BSS), how does the passive scanning process occur?

  A. Access pointsbroadcast Beacons on all channels of each radio within the regulatory domain. Nearby client stations record information found in the Beacons for use in the association process.

  B. Client stations broadcast Probe Request frames on all supportedchannels inthe regulatory domain. Nearby access points respond with Probe Response frames. Client stations record information in the Probe Response frames for use in the association process.

  C. Client stations broadcast Probe Request frames on the singlechannel forwhich they are programmed. Nearby access points respond on that channel with Probe Response frames. Client stations record information found in the Probe Response frames for use in the association process.

  D. Access points broadcast Beacons on asingle channel for which they are programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.

  Correct Answer: D

• Question 10:

  As XYZ Company's wireless specialist, you have been asked to troubleshoot some unexpected frame patterns in a wireless protocol capture. Your peers explain that the network'sbeacon frames are inconsistent. That is, the BSSID is the same for all beacons, but the source address varies between three different addresses.

  What network configuration would cause this beacon frame behavior?

  A. A single AP supports multiple BSSs withdifferent SSIDs

  B. A virtual cell single channel network has been implemented

  C. The beacons are from an IBSS instead of a BSS

  D. Three APs still share the same default configuration.

  Correct Answer: C
