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

• Question 102:

  In an enterprise WLAN, what condition will prevent a dual-band HT client device from performing a fast and seamless transition (i.e. latency-sensitive applications are not disrupted) between two access points that are managed by the same WLAN controller?

  A. The current AP is using channel 1 and the new AP is using channel 40.
  B. The SSID of the current AP does not match the SSID of the new AP.
  C. The current AP supports only ERP and the new AP is HT capable.
  D. The access points are hiding the SSID in Beacons and Probe Response frames.
  B. The SSID of the current AP does not match the SSID of the new AP.

• Question 103:

  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. What network functions are performed by the enterprise-class WNMS? (Choose three)

  A. RF pre-deployment planning and post-deployment reporting of access point locations on a floor plan
  B. Performance and security monitoring of WLAN controllers with alarms and notifications for administrative staff
  C. Radio management, fast roaming, key caching, and other centralized control plane operations
  D. Centralized bridging of guest data traffic and application of firewall and QoS policies to data
  E. Management of WLAN controller configuration and provisioning of firmware updates
  F. Generating, encrypting, and decrypting 802.11 frames and collecting RF radio data.
  A. RF pre-deployment planning and post-deployment reporting of access point locations on a floor plan

• Question 104:

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

  A. Access points broadcast 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 supported channels in the 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 single channel for which they are programmed. Nearby access points respond on that channel with Probe Response frames. Clientstations record information found in the Probe Response frames for use in the association process.
  D. Access points broadcast Beacons on a single channel for which it is programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.
  D. Access points broadcast Beacons on a single channel for which it is programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.

• Question 105:

  As a consultant, you've been hired by XYZ Company to provide recommendations about client device selection, operation, and interoperability. What information should be considered to help them choose the right WLAN client devices?

  A. 802.11n OFDM is more susceptible to high-power, narrowband interference than 802.11a OFDM.
  B. In order to earn Wi-Fi Alliance certification, 802.11n clients stations are required to support both 2.4 and 5 GHz frequencies
  C. 802.11a/g devices may support WMM, but all 802.11n devices are required to support WMM.
  D. An 802.11g/n AP that is configured to support only OFDM data rates will allow HR/DSSS devices to associate.
  E. When HR/DSSS devices are present, HT MCS rates are disabled for the entire BSS.
  C. 802.11a/g devices may support WMM, but all 802.11n devices are required to support WMM.
