Implementing Cisco unified Wireless Voice Networks (IUWVN) v2.0

Question No: 41

VoWLAN implementation plans for a current mix of existing Cisco Unified Wireless IP Phones 7920G and 7921G to a final migration of Wireless IP Phones 7925G in a single WLAN. What would be the most appropriate WLC WLAN configuration to end with Wireless IP Phones 7925G?

  1. 7920 Client CAC = enabled only; Radio Policy = All; WMM = Disabled

  2. 7920 AP CAC = enabled only; Radio Policy = All; WMM = Allowed

  3. 7920 Client CAC = enabled only; Radio Policy = 802.11a only; WMM = Disabled

  4. 7920 AP CAC = enabled only; Radio Policy = 802.11a only; WMM = Allowed

  5. 7920 Client CAC = enabled only; Radio Policy = 802.11b/g only; WMM = Disabled

  6. 7920 AP CAC = enabled only; Radio Policy = 802.11b/g only; WMM = Allowed

Answer: B

Question No: 42

A Cisco WLC v7.0 is configured with the default setting for wired and wireless QoS. When a wireless client sends a voice packet to the AP, how does the AP mark the outer CAPWAP header when the packet is sent to the Cisco WLC v7.0?

  1. The AP uses the wireless priority value to create a matching 802.1p value in the CAPWAP header.

  2. The AP uses the wireless priority value to create a matching DSCP value in the CAPWAP header.

  3. The AP uses the wireless priority value to create both a matching 802.1p and DSCP value in the CAPWAP header.

  4. The AP does not match the value to the CAPWAP header, which results in best effort.

Answer: D

Question No: 43

What are the two equivalent 802.1p CoS categories that are associated with 802.11e AC_BE? (Choose two.)

  5. 4

  6. 5

Answer: A,D

Question No: 44

Which two statements describe information that you can derive from the WCS v7.0 output from the Monitor Client Detail? (Choose two.)

  1. Comparing the RSSI and SNR can provide specific information on where the client has roamed and if there is a problem with one or more AP configurations.

  2. Comparing the information to the location of the client can provide the first hint of voice- related issues.

  3. If the parameters are consistently good, then voice-related issues being reported by users are probably not related to RF parameters.

  4. Comparing the RSSI and SNR can provide specific information on QoS performance in the VoWLAN.

  5. Comparing the RSSI and SNR can provide specific information on the relative distance of the client from the AP during a call.

Answer: B,C

Question No: 47

A wired packet that is marked for QoS priority CS4 arrives on VLAN-4 at Cisco WLC v7.0,

with a destination of a WLAN SSID-4. The Cisco WLC is configured for the wired and wireless QoS level of Silver. The infrastructure routers and switches have incorrect QoS configurations. They have mismarked the CAPWAP outer header to a QoS priority EF.

Which statement is true about how the packet is sent from the AP to the final WMM wireless client?

  1. The AP sends the packet with an 802.11 priority tag of 0 (Best Effort).

  2. The AP sends the packet with an 802.11 priority tag of 3 (Silver).

  3. The AP sends the packet with an 802.11 priority tag of 5 (Gold).

  4. The AP sends the packet with an 802.11 priority tag of 6 (Platinum).

Answer: A

Question No: 48

Which two applications benefit from upgrading to 802.11n? (Choose two.)

  1. voice

  2. video

  3. database access

  4. digital imaging

  5. SMS

  6. email

Answer: B,D

Question No: 49

A Cisco 7925 phone at a client#39;s location is not registering with CUCM. The engineer analyzes a packet capture, sees that the phone receives an IP, and downloads the proper configuration file from TFTP successfully. What type of messages should the phone be sending at this point?

A. H.245

B. H.323

  1. MCGP

  2. SCCP

Answer: D

Question No: 50

A downstream packet containing a DSCP value arrives at the WLC Ethernet interface from the wired source network. The WLC is configured for QoS WLAN 802.1p mapping. How does the WLC treat the CAPWAP QoS marking when leaving the controller interface for the respective AP and final wireless client destination?

  1. No outer CAPWAP or inner QoS tagging is applied.

  2. No outer CAPWAP QoS tag is applied, but the original DSCP is maintained inside CAPWAP.

  3. The outer CAPWAP CoS is marked and capped while the inner DSCP maintains the original marking.

  4. The outer CAPWAP DHCP is marked and capped without any inner DSCP value.
