Question 1. Quality of Service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies. You are configuring a Cisco Wireless LAN Controller to utilize QoS and have configured the platinum queue on the controller. However, the Cisco Catalyst 3750 Series Switch to provide the necessary QoS for voice clients on the wireless network? A. Enable 802dot1p B. Config wlan qos wlan-id platinum C. Swithchport priority extend cos 5 D. Mls qos trust dscp Answer: D Question 2. Which properties are of an AP in H-REAP mode? A. Allows some SSID/VLAN traffic to be switched locally while other SSID/VLAN traffic has full LWAPP functionality B. Support Cisco Centralized Key Management fast roaming C. Can switch client data traffic locally D. Perform client authentication locally when its connection to the controller is lost Answer: A, B, C, D Question 3. Can you tell me what the LWAPP data and control port numbers are? A. UDP 12222 and 12223 B. UDP 16666 and 16667 C. TCP 12124 and 12134 D. TCP 16666 and 16667 Answer: A Question 4. The IEEE 802.11 standards define different encryption mechanisms. Which is the basic of defining the most secure encryption solution in IEEE 802.11 standards? A. WEP B. AES-CCMP C. IPSEC D. TKIP Answer: B Question 5. In the AP Layer 3 controller discovery process, after the LWAPP Discovery Request is broadcast on a local subnet, which action will AP take next? A. Send an LWAPP discovery request to controllers learned via OTAP if operational B. Wait 5 seconds and resend a Discovery Request to the local subnet C. Send an LWAPP response to the master controller if known D. Determine whether the controller response are the primary controller Answer: A Question 6. A client is attached to the Cisco Unified Wireless network by use of controllers. When the client is using WPA2 and EAP authentication, where are the wireless encryption keys located during the active user session? (Choose two.) A. On the Cisco WCS B. On the RADIUS Server C. On the Access Point D. On the Client Answer: C, D Question 7. Harry is a network engineer for a company, he is now upgrading a large autonomous WLAN deployment to LWAPP operation. He has successfully imported a X.509 self-signed certificate into the WLC. But, when he tries to add additional self-signed certificates, the WLC GUI reports a "Failed to Add entry" error. Which command can diagnose the root cause of this problem? A. Show exlusionlist B. Show database summary C. Show sysinfo D. Show wps summary Answer: B Question 8. Can you tell me when a client will provide an AP with its version of Cisco Compatible Extensions for WLAN devices? A. In an 802.11 association or reassociation request frame B. When the AP sends an unsolicited update embedded in a beacon packet C. Upon successful EAP or dot1x authentication to the AP D. In a Broadcast probe request packet Answer: A Question 9. Wi-Fi Multimedia is a technology maintaining the priority of audio, video and voice applications in a Wi-Fi network so that other applications and traffic are less likely to slow them. A. Definition of the differentiated services filed B. Enhanced Distributed Coordination Function mechanism C. Four Access categories: A label for the common set of Enhanced Distributed Channel Access parameters that are used by a WMM STA to contend for the channel in order to transmit MSDUs with certain priorities D. Unscheduled Service Period. The service period that is started when a WMM STA transmits a trigger frame to the WMM AP Answer: B, C, D Question 10. Before sending a frame over a medium and verifying that the medium is free, which process does a wireless client go through? A. Send an RTS frame, receive a CTS frame, then transmit the frame B. Verify that NAV = 0, then transmit the frame C. Send a CTS frame, receive an RTS frame, then transmit the frame D. Check that NAV = 0, generate a random backoff, verify that the channel is free, verify that slot times = 0, then transmit the frame Answer: D
