WLAN controller. After configuration has been completed, the administrator found that computers could authenticate; however, the VoIP phones could not. What is the problem given the output?

  1. The EAP request-timeout is too short for the wireless phone to process the PAC from the WLAN controller.

  2. The EAP Broadcast Key interval is set to 1 hour however should be 8 hours.

  3. EAPOL-Key Max Retries should be set to 12 to ensure the wireless phone can authenticate.

  4. EAPOL-Key timeout should be set to at least 20,000 Milliseconds to allow the PAC to be processed.

Answer: A

You have a VoWLAN configured for platinum QoS, WMM, and CAC. IP phones for this VoWLAN include the Nokia and Cisco Unified Wireless IP Phones 7920G (pre-v2.0 firmware), 7921G, and 7925G. The Wireless IP Phones 7921G and 7925G work properly, but the Nokia and the Wireless IP Phones 7920G associate with the WLAN but cannot place calls. What is the issue?

  1. The lowest mandatory speed in the WLAN is too high and needs to be reduced.

  2. The Cisco Unified Wireless IP Phones 7920G and Nokia IP phones do not support TSPEC.

  3. EDCA needs to be enabled on the WLAN.

  4. HCCA needs to be enabled on the WLAN.

  5. The reserved roaming bandwidth setting is set too low.

  6. The expedited bandwidth setting needs to be enabled.

Answer: B

Question No: 25

Which one of these options best describes the ideal WLAN design for wireless VoIP clients?

  1. smaller cells with all configurable speeds to ensure that all clients (802.11a/b/g) can associate to the wireless infrastructure

  2. smaller cells with higher speeds and CAC-enabled prioritization of WMM clients

  3. larger cells with higher speeds and WPA2 security enabled to ensure the best possible coverage

  4. smaller cells with APs in the inner areas using omnidirectional antennas, and APs on the outer walls using directional antennas facing inward

Answer: B

Question No: 26
