Q1. 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
Q2. A customer called into the support center with a problem ticket that involves wireless clients having to reauthenticate when they are walking around their office. After further investigation, it was discovered that the customer has two controllers in an N+1 deployment. Which action must the engineer take to troubleshoot the issue?
A. Verify that the wireless controllers are in the same mobility group and that the access points are all on the primary controller.
B. Under the SSID, make sure that 802.1 Iris configured and running for the clients.
C. Make sure that the SSID has the authentication set to 802.1x with Cisco Centralized Key Management so the data clients can roam seamlessly.
D. Verify the access points are spread out between the primary and secondary controller and that the controllers are in the same mobility group.
Answer: D
Q3. A customer has implemented several WLANs in an auditorium utilizing a newly dedicated WLC and is experiencing excessive channel utilization regardless of occupancy. Which action reduces channel utilization without removing SSIDs?
A. Disable MCS data rates 0 through 11.
B. Disable MCS data rates used by 40 MHz channels.
C. Disable data rates that use CCK.
D. Disable VHT data rates.
Answer: C
Q4. A customer has limited staff to manage a wireless network. The customer wants a solution that requires minimum hardware. Which type of architecture do you propose?
A. centralized
B. distributed
C. cloud-based
D. unified
Answer: A
Q5. What address do PIM routers listen to in order to automatically discover the best RP for each multicast group?
A. 224.0.0.13
B. 224.0.1.39
C. 224.0.0.14
D. 224.0.140
Answer: D
Q6. Which show command will show whether a WLAN is locally or centrally switched on a Cisco Wireless Lan Controller?
A. show ap config general Cisco_AP
B. show wlan wlan_id
C. show flexconnect summary
D. show flexconnect group detail
Answer: B
Q7. 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
Q8. A customer has "quiet" wireless clients that use static IP addresses. Which two WLAN configurations are required for these wireless clients to connect properly? (Choose two.)
A. Disable DHCP address assignment required.
B. Enable passive client.
C. Disable allow AAA override.
D. Enable static IP tunneling.
E. Disable DHCP server override.
Answer: A,E
Q9. 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?
A. controller IGMP snooping
B. unicast AP Multicast Mode
C. broadcast forwarding
D. multicast AP Multicast Mode
Answer: B
Q10. Which statement about when you configure FlexConnect APs and you want to set up Cisco Centralized Key Management fast roaming is true?
A. FlexConnect groups are required for Cisco Centralized Key Management fast roaming to work with FlexConnect access points.
B. APs that are in the same FlexConnect group but associated to different WLCs support Cisco Centralized Key Management.
C. Cisco Centralized Key Management fast roaming among FlexConnect and non-FlexConnect access points is supported.
D. The FlexConnect access point must be in standalone mode to support Cisco Centralized Key Management.
Answer: A
