Q6. A customer has implemented a N+1 high availability plan in a multistory building. All APs on odd numbered floors are set as primary to WLC-A and all APs on even numbered floors are set as primary to WLC-8. Which two problems are likely to arise from this design? (Choose two)
A. inconsistent CleanAir data due to multiple WLCs
B. floor-to-floor bleed-through that causes intercontroller roaming delays
C. AVC inconsistency due to multiple mobility group members
D. legacy device compatibility with multiple WLC configuration that causes disconnects
E. unpredictable AP loading during a WLC failure
Answer: A,C
Q7. CORRECT TEXT
Scenario
One of your colleagues has setup a test network in the lab to simulate a new building atone of your regional offices. Your team is testing AP failover. Your colleague has requested you to configure the WLCs so that in the event of a loss of one of the WLCsthe other wings APs will fail over to the remaining WLC.
The APs on the East-WLC-2504A should fail over to the West-WLC2-2504A, and the APs on the West-WLC2-2504A should fail over to the East-WLC-2504A.
Set the priority of the APs so the backup controller recognizes the join request from the higher-priority AP and if necessary disassociates a lower-priority AP to provide access to an available port.
Not all menus, tabs and features are supported.

Q8. After a wireless deployment, users report that wireless voice clients are experiencing an unacceptable amount of delay while roaming during a call on the Cisco Unified 7925 Series phones. The customer environment consists of multiple controllers, all running 7.4.121.0 code, operating in a centralized deployment. What configuration issue is most likely contributing to the problem?
A. The authentication should be set to WPA2-PSK to allow for 802.11n speeds for the Cisco Unified 7925 phones.
B. The access points on that floor are all on one controller and should be load balanced evenly across multiple controllers.
C. The access points for that floor are salt and peppered across multiple controllers and should be moved to the primary controller.
D. The wireless phones are operating in the 2 4 GHz band and should be configured for the 5 GHz band.
Answer: B
Q9. What devices can be tracked with the Cisco Context Aware Services?
A. Only wired devices.
B. Both wired and wireless devices.
C. Only Cisco certified wireless devices.
D. Only wireless devices.
Answer: B
Q10. CMX Facebook WiFi can allow access to the network before authentication. Which two of the following options are available? (Choose two)
A. Allow all the traffic before authentication and intercept HTTPs only.
B. Allow HTTP traffic only before authentication and block all the traffic.
C. Allow SNMP traffic only before authentication and block all the traffic.
D. Allow all the traffic before authentication and intercept HTTP only.
E. Allow HTTPs traffic only before authentication and block all other traffic.
Answer: B,D
Q11. What is the best practice for setting the WLC v7.0 use of WLAN QoS settings to support SIP phones on a VoWLAN?
A. Configure SIP with static CAC only with SIP call snooping.
B. Configure SIP with static CAC only without SIP call snooping.
C. Configure SIP with load-based CAC only with SIP call snooping.
D. Configure SIP with load-based CAC only without SIP call snooping.
E. Configure SIP with load-based CAC and TSPEC only with SIP call snooping.
Answer: A
Q12. You have just added a new MSE to Prime Infrastructure and want to synchronize the MSE with your 5508 WLC. which is located behind a firewall in a DMZ. You notice that NMSP messages are failing between the two devices. What traffic needs to be allowed on the Firewall to ensure the MSE and WLC can communicate using NMSP?
A. UDP 16113
B. TCP 1613
C. TCP 16113
D. UDP 1613
Answer: C
Q13. A network engineer observes a spike in controller CPU overhead and overall network utilization after enabling multicast on a controller with 500 APs. What feature is necessary to correct the issue?
